Water is pumped up to a water tower, which is 92.0m high. The flow rate up to the top of the tower is 75.0 L/s and each liter of water has a mass of 1.00 kg. What power is required to keep up this flow rate to the tower? (pls explain steps!)

Answers

Answer 1

The power required is  66.09 kW for maintaining a flow rate of 75.0 L/s to a water tower that stands 92.0m high, the steps for calculation will be explained.

The power required to maintain the flow rate to the water tower can be determined by considering the amount of work needed to lift the water against gravity.

First, we need to find the mass of water being pumped per second. Since each litre of water has a mass of 1.00 kg, the mass of water per second would be:

75.0 kg/s (75.0 L/s * 1.00 kg/L).

Next, calculate the work done to lift the water. The work done is given by the formula:

W = mgh,

where m is the mass, g is the acceleration due to gravity (approximately 9.8 m/s²), and h is the height of the tower.

Plugging in the values,

\(W = (75.0 kg/s) * (9.8 m/s^2) * (92.0 m)\)

= 66,090 J/s (or 66.09 kW).

Therefore, the power required to maintain the flow rate of 75.0 L/s to the tower is approximately 66.09 kW. This power is needed to overcome the gravitational force and lift the water to the height of the tower.

Why is speed the magnitude of velocity?

Why is speed the magnitude of velocity?

Answers

Yes, Speed is the magnitude of its velocity.


What is speed?

Speed is a scalar, while velocity is a vector (just a number). A velocity, on the other hand, has both a direction and a magnitude. As previously stated, the magnitude of the velocity is referred to as the speed.

The speed of a moving object is the distance it travels in a given amount of time.

The distance travelled divided by the time gives the average speed of an object in a given time. The speed of an object is defined as the distance travelled per unit of time. When the speed of an object changes, it becomes faster or slower. When the speed of an object increases, this is referred to as acceleration. Deceleration, also known as negative acceleration, occurs when an object slows down as its speed decreases.

what is the name of the part of the microscope that the objectives are attached to? (choose the best answer)

Answers

The part of the microscope that the objectives are attached to is called the (C) nosepiece.

The nosepiece is a rotating mechanism located below the microscope's body tube. It holds the objectives, which are the lenses responsible for magnifying the specimen. The nosepiece typically has multiple positions, allowing the user to switch between different objective lenses for varying levels of magnification.

This convenient feature eliminates the need to manually remove and replace objectives when changing magnification. By rotating the nosepiece, different objectives can be brought into position above the specimen. This allows for quick and efficient adjustments in magnification without disrupting the viewing process.

Hence, the nosepiece plays a critical role in the microscope's functionality by providing a convenient way to switch between objectives and adjust the magnification level.

the specific volume of water vapor at 0.3 mpa, 160 °c is 0.651 m3/kg. molecular weight of water vapor is 18.02 kg/kmol. if the water vapor occupies a volume of 2 m3, determine: (a) the amount present, in kg and kmol

Answers

The amount of water vapor present in a volume of 2 m3 can be determined using the specific volume and molecular weight. The amount is approximately 3.075 kg and 0.1707 kmol.

The specific volume of water vapor at a given pressure and temperature is given as 0.651 m3/kg. This means that for every kilogram of water vapor, it occupies a volume of 0.651 m3. We are given that the water vapor occupies a volume of 2 m3. To find the amount of water vapor present, we can use the equation:

Amount of water vapor = Volume / Specific volume

Substituting the given values, we have:

Amount of water vapor = 2 m3 / 0.651 m3/kg

Calculating this, we find that the amount of water vapor present is approximately 3.075 kg.

To determine the amount in kilomoles (kmol), we need to divide the mass by the molecular weight of water vapor. Given that the molecular weight of water vapor is 18.02 kg/kmol, we can calculate the amount in kilomoles:

Amount in kmol = Amount in kg / Molecular weight

Substituting the values, we have:

Amount in kmol = 3.075 kg / 18.02 kg/kmol

Calculating this, we find that the amount of water vapor present is approximately 0.1707 kmol. Therefore, the amount of water vapor present in a volume of 2 m3 is approximately 3.075 kg and 0.1707 kmol.

How to determine kinetic energy?

To calculate the kinetic energy of each vehicle, use the formula:

Kinetic Energy (KE) = 1/2 × mass × velocity²

Given the mass and velocity of each vehicle, plug in the values and calculate the kinetic energy.

For the truck:

Mass = 6,000 kg

Velocity = 92 km/h

= 92,000 m/3600 s

≈ 25.56 m/s

Using the formula:

KE = 1/2 × 6,000 kg × (25.56 m/s)²

Calculating the result:

KE = 1/2 × 6,000 kg × 655.3936 m²/s²

KE ≈ 1,964,180 Joules

Therefore, the kinetic energy of the truck is approximately 1,964,180 Joules.

Answers

Light rays first pass through the transparent layer called the cornea and then refracted again as they pass through the transparent lens.

How do light rays flow in the eyes?

The first factor in the journey of light via the eye is the objects being seen and how they produce, reflect, or change the light in various ways.

The visual cortex of the brain's occipital lobe serves as the destination of the light pathway, which starts with photoreceptors in the retina. Rod and cone cells are two different types of photoreceptors. When it comes to eyesight in low light and in peripheral vision, rods can be especially helpful.

The cornea is where most of the refraction occurs as light enters the eye's curved, transparent front surface. The natural or crystalline lens of the eye also distorts light rays. When an item passes in front of the eye, its rays pass through the transparent cornea and enter the eye.

Additionally, devices like elevators and escalators also rely on Newton's laws of motion. Elevators use Newton's second law (force equals mass times acceleration) to lift or lower passengers. Escalators, on the other hand, utilize Newton's first and second laws to transport people between different levels.
These gadgets and devices demonstrate the practical application of Newton's laws of motion in everyday life, enhancing safety, transportation, and convenience.

If we throw a socks in to the bowl then it is going with a few unfold situation by means of the projectile and follows the trajectory. Crumpled paper use for the projectile additionally works gud for the simulation.

Crumpled paper has irregular form and mild in weight and it is able to divert in a way by air force or by means of any other motive mild weight. hence simulation and projectile interest are interlinked to every different.

Projectile motion is used in many real-life applications such as designing rockets, ballistic missiles, and artillery, as well as in sports such as baseball, golf, and archery. The concept of projectiles is also relevant in fields such as engineering, military science, and sports. For example, the design of a projectile such as a bullet or missile can affect its accuracy and effectiveness, while knowledge of projectile motion can aid in the design of sports equipment such as golf clubs or javelins.

When a projectile is launched, it follows a curved path known as a trajectory, which is determined by the initial velocity, angle of launch, and the gravitational and atmospheric forces acting on it. The motion of projectiles is studied in physics, where concepts such as projectile motion, trajectory, range, and maximum height are analyzed.

Item 4 In a heat engine, 500 J of heat enters the system, and the piston does 300 J of work. What is the final internal (thermal) energy of the system if the initial energy is 1500 J

Answers

The final internal (thermal) energy of the system is 1700 J.

To determine the final internal energy of the system, we need to consider the conservation of energy in the heat engine. The heat engine is a device that converts heat energy into mechanical work. In this case, 500 J of heat enters the system and 300 J of work is done by the piston.

The change in internal energy of the system is given by the equation:

Change in internal energy = Heat input - Work done

Substituting the given values, we have:

Change in internal energy = 500 J - 300 J

Change in internal energy = 200 J

To find the final internal energy, we need to add the change in internal energy to the initial energy of the system. The initial energy is given as 1500 J.

Final internal energy = Initial energy + Change in internal energy

Final internal energy = 1500 J + 200 J

Final internal energy = 1700 J

Therefore, the final internal (thermal) energy of the system is 1700 J.

according to pe = mgh, gravitational potential energy is the same thing as

Answers

The equation PE = mgh relates gravitational potential energy to mass, acceleration due to gravity, and height, gravitational potential energy itself is a distinct concept representing the energy associated with an object's position in a gravitational field.

According to the equation PE = mgh, gravitational potential energy (PE) is the product of mass (m), acceleration due to gravity (g), and height (h). However, gravitational potential energy is not the same thing as any of these individual quantities.

Gravitational potential energy refers to the energy possessed by an object due to its position in a gravitational field. It represents the potential for the object to do work when it is released and allowed to fall or move under the influence of gravity.

Mass (m) represents the amount of matter an object contains, acceleration due to gravity (g) represents the strength of the gravitational field, and height (h) represents the vertical distance from a reference point to the object. These quantities are used together in the equation to calculate the gravitational potential energy of the object.

The vector BR in unit vector notation is:

BR = 8.485 î + 8.485 j

What is Vector?

Vectors can be added together to find the result, which is known as the vector sum. The vector sum can be found using the head-to-tail method, where the tail of one vector is placed at the head of the other vector. The vector sum is the vector that goes from the tail of the first vector to the head of the second vector.

To write the vector BR in unit vector notation, we need to find its components in the i and j directions.

Given that the magnitude of the vector is 12.0 and it makes an angle of 45 degrees with the positive x-axis, we can use trigonometry to find the components.

The x-component (i-direction) of the vector is given by:

Bx = B cos θ = 12.0 cos 45° = 8.485

The y-component (j-direction) of the vector is given by:

What is the bandwidth (in hz) of a system with the frequency response that follows?

Answers

The bandwidth of a system is the difference between the highest and lowest frequencies in the system's frequency response.

In order to determine the bandwidth of the system in question, we need to know the highest and lowest frequencies in the frequency response.
If the frequency response is given in a graph or table, you can find the highest and lowest frequencies by looking at the x-axis values. The highest frequency will be the largest x-axis value, and the lowest frequency will be the smallest x-axis value.
Once you have the highest and lowest frequencies, you can calculate the bandwidth by subtracting the lowest frequency from the highest frequency. For example, if the highest frequency is 1000 Hz and the lowest frequency is 100 Hz, the bandwidth would be 900 Hz (1000 Hz - 100 Hz = 900 Hz).
Without the frequency response information, it is not possible to accurately determine the bandwidth of the system.

particles q_1 = -8.99uc, q_2 = +5.16uc, and q_3=-89.9uc are in a line. particles q_1 and q_2 are separated by 0.220m and particles q_ 2 and q_3 are separated by 0.330m. what is the net force on particles q_1?

Answers

According to the question the net force on particle q1 is \(1.45 * 10^-4 N.\)

What is force?

Force is an influence that produces a change in the motion, direction, shape, or orientation of an object. It is a vector quantity, meaning it has both magnitude and direction. Force can be derived from different sources, including physical contact, gravity, magnetism, or even electrical fields. Force affects objects by producing acceleration, deceleration, or changes in direction.

The net force on particle q1 is the sum of the forces due to the two other particles. The force on particle q1 due to particle q2 is given by Coulomb's Law:

\(F12 = k(q1q2/r12^2)\)

Where k is the Coulomb's Constant, q1 and q2 are the charges of the two particles, and r12 is the distance between them, which is 0.220m.

Similarly, the force on particle q1 due to particle q3 is given by:

\(F13 = k(q1q3/r13^2)\)

Where q1 and q3 are the charges of the two particles, and r13 is the distance between them, which is 0.330m.

The net force on particle q1 is then the vector sum of these two forces:

Fnet = F12 + F13

Substituting the values for the charges and distances into Coulomb's Law gives:

\(Fnet = (9*10^9)(-(8.99*10^-6)(5.16*10^-6)/(0.22^2)) + (9*10^9)(-(8.99*10^-6)(-89.9*10^-6)/(0.33^2))\)

Simplifying, we get

\(Fnet = 1.45 * 10^-4 N\)

Therefore, the net force on particle q1 is\(1.45 * 10^-4 N.\)
