A student builds a series circuit using three 1-ohm resistors. The current in the circuit is 1.5 amps. What is the voltage drop across each resistor?
(no explanation is needed! i just need the answer)
Answers
ANSWER:
Charge flows together through the external circuit at a rate that is everywhere the same. The current is no greater at one location as it is at another location. The actual amount of current varies inversely with the amount of overall resistance. There is a clear relationship between the resistance of the individual resistors and the overall resistance of the collection of resistors. As far as the battery that is pumping the charge is concerned, the presence of two 6-Ω ;resistors in series would be equivalent to having one 12-Ω resistor in the circuit. The presence of three 6-Ω resistors in series would be equivalent to having one 18-Ω resistor in the circuit. And the presence of four 6-Ω resistors in series would be equivalent to having one 24-Ω resistor in the circuit.

For this assignment, you will research how to design and build a solar cooker. Search reliable online sites
for “solar cookers.” After getting the materials you need from your teacher, you will present your initial
design as a drawing or illustration. You will then build your device and test its efficiency by warming up a
hot dog until it reaches an internal temperature of 165°F, recording how long it took you to reach this
temperature. Based on your tests, you will make recommendations on how to improve the design of your
solar cooker, and then present your final design and the logic that supports it in a lab report. Your lab
report should include a title, a list of materials that you used to build your solar cooker, a drawing of your
initial design, observations from your experimental tests, recommendations for a final design based on
what you know about radiation, a drawing of your final design, and the results of the efficiency test. To
help you write your lab report, there is a Student Worksheet on the last few pages of this document.

Answers
Answer:
One household appliance that works on the basis of electric current is a washing machine. It works by first drawing in water from the water supply, and then pumping it into the drum where the clothes are added. The washing machine then agitates the clothes with a rotating inner drum, which is powered by an electric motor. The motor is powered by electric current, which is supplied by the electrical outlet. As the drum rotates, the electric current causes the motor to turn, which in turn agitates the clothes. The effects of the electric current are seen in the form of heat generated by the motor, and a buzzing noise during operation.

The velocity of the vehicle is equal to 406.5 m/s. The velocity in Km/hr is 1463.4 Km/hr.
What is the velocity?Velocity can be demonstrated as a vector measurement of the direction of the object and the rate of motion of an object. The velocity of an object can be described as the change in the body's position w.r.t. time.
Velocity can be expressed as a vector quantity as it consists of magnitude as well as direction. A mathematical formula common and simplest way to find velocity.
v = d / t
Where v is the velocity, d is the distance covered and t is the time taken by the body.
The S.I. unit for velocity can be represented as m/s and can be expressed in terms of miles per hour (mph), and kilometers per hour (kph).
Given, the distance traveled by the vehicle, d = 100 m
The time taken by vehicle = 0.246 sec
The velocity of the vehicle, v = 100/0.246 = 406.5 m/s
We know that 1km = 1000m then 1 m = 10⁻³ Km
1 hour = 60 ×60 = 3600 s
1s = 1/3600 hr
Therefore, velocity, \(\displaystyle v = 406.5 \times \frac{3600}{1000} Km/hr\)
v = 1463.4 Km/hr
Learn more about velocity, here:
brainly.com/question/19979064
#SPJ2
Velocity = Distance / Time = 100 m / 0.246 s = 406.50 m/s
To convert m/s to km/hr, we need to multiply the velocity by 3.6:
Velocity in km/hr = Velocity in m/s x 3.6 = 406.50 m/s x 3.6 = 1463.80 km/hr
The steps I took to convert from m/s to km/hr were to multiply the velocity in m/s by 3.6, which is the conversion factor between meters per second and kilometers per hour.

Mass = m = 50 kg
Height = h = 20 m
Acceleration due to gravity = g = 10 m/s²
Required:
Potential Energy = P.E. = ?
Formula:
P.E. = mgh
Solution:
P.E. = (50)(20)(10)
P.E. = 10,000 Joules
P.E. = 10 * 10³ Joules (10³ = Kilo)
P.E. = 10 kJ

Answers
Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.
Explanation:
Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping
If a 1,500 kg car and a 4,000 kg truck were moving at the same speed down a steep hill, what statement is false?
A: The truck will have greater kinetic energy and be more difficult to stop.
B: The car has less mass, and therefore less kinetic energy, when compared to the truck.
C: Both vehicles would have their greatest kinetic energy as they reached the base of the hill.
D: The car's potential energy will be greatest when at its highest speed.
Answers
Answer:a
Explanation:because if you have a bigger or heavier truck I can be harder to stop then a car
The car kinetic energy not potential energy is greatest when at its highest speed.
Kinetic Energy:
It is the energy of the object which is due to the motion of object. The formula of kinetic energy is
\(\bold {KE = \dfrac 1{2} m v^2}\\\)
Where,
m - mass
v - velocity
The kinetic energy of the object is directly proportional to the mass of the object and square of the velocity of the object.
So, A, B and C are correct statement.
Therefore, the car kinetic energy not potential energy is greatest when at its highest speed.

Describe 3 factors an engineer should take into consideration when choosing material for building the pipes in a pipeline
Gr. 8
Think it has something to do with Viscosity, Density, and Pressure but not sure what
Answers
Answer: 1. Material being transported 2. The temperature of the material being transported 3. How long the pipes will be there (lifespan)
Explanation: 1. - The pipe builder should consider the material being transported to choose the correct material of the pipes to use, so they last long and can hold the material.
2. - Similar to 1, the pipe builder should consider the temperature of the material to choose the correct material of the pipes to use, so the pipes don’t break and function properly.
3. - If the pipe builder uses a material that can hold the material, that’s great! If that material will last a short time, it would not work if the pipes were to be used for a long time.
The things you said before about viscosity, density, and pressure are also correct. The correct answers are mainly talking about factors of the material being used in the pipes.
