Answers
A hallmark of courage is being ready and willing to face challenging or uncomfortable circumstances. The word "bravery" is similar. It can also include doing so, even though confronting these situations fearlessly is generally thought of as showing courage.
In reality, courage is the capacity to move forward in the face of fear. The ability to behave bravely in the face of any anxiety or tension is what is meant by having courage. One of the finest ways to be courageous is to recognize your fears and then decide not to let them stop you. having the guts to handle risk in a responsible manner as opposed to acting cowardly or irrationally confident.

how far must a 3.18x10-4c charge be moved in a 3470n/c electric field to store 5.53j
Answers
To determine how far a charge must be moved in an electric field to store a certain amount of energy, we can use the formula:
\[E = qV\]
where E is the energy, q is the charge, and V is the voltage or electric potential.
In this case, the charge (q) is given as 3.18x10^(-4) C, and the energy (E) is given as 5.53 J. We need to find the distance (d) the charge must be moved, which is equivalent to finding the voltage (V).
Rearranging the formula, we have:
\[V = \frac{E}{q}\]
Substituting the given values:
\[V = \frac{5.53 \, \text{J}}{3.18 \times 10^{-4} \, \text{C}}\]
Solving this equation, we find the voltage to be:
\[V \approx 1.7384 \times 10^4 \, \text{V}\]
Now, we can use the formula for electric potential energy to determine the distance (d) the charge must be moved. The formula is:
\[V = Ed\]
Rearranging the formula to solve for d:
\[d = \frac{V}{E}\]
Substituting the values:
\[d = \frac{1.7384 \times 10^4 \, \text{V}}{5.53 \, \text{J}}\]
Evaluating this equation, we find the distance to be:
\[d \approx 3142.58 \, \text{m}\]
Therefore, the charge must be moved approximately 3142.58 meters in the 3470 N/C electric field to store 5.53 J of energy.

A car accelerates at -1 m/s2. What is its final speed (in m/s) at the end of 4 seconds if it started at 1 m/s? (round
to the nearest whole number)
Answers
This is an exercise in Rectilinear Uniformly Varied Motion (MRUV) is a type of motion in which an object moves in a straight line and experiences changes in its velocity at a constant rate. In this type of motion, the acceleration of the object remains constant over time.
The distinctive feature of the MRUV is that the velocity of the object changes uniformly, that is, its velocity increases or decreases by a constant amount in each unit of time. If the object experiences a positive acceleration, its velocity increases with time. On the other hand, if the object experiences a negative acceleration, its speed decreases.
In an MRUV, constant acceleration has a direct impact on displacement and the time it takes for the object to reach a certain speed. Also, the direction of the acceleration determines whether the object is accelerating or decelerating relative to its initial motion.
This type of movement is found in various situations of daily life, such as the launch of an object upwards and its subsequent fall, the movement of cars on a road with acceleration or braking, or even the study of bodies in free fall.
To solve this problem, we can use the kinematics formula for constant acceleration:
Vf = V₀ + a × t
Where:
Vf is the final speedV₀ is the initial velocitya is the accelerationt is the timeIn this case, the initial velocity (vi) is 1 m/s, the acceleration (a) is -1 m/s^2 (negative because it indicates deceleration), and the time (t) is 4 seconds.
Substituting these values into the formula, we get:
Vf = V₀ + a × t
Vf = 1 m/s + (-1 m/s²) × 4 s
Vf = 1 m/s - 4 m/s
Vf = -3 m/s
The final velocity of the car at the end of 4 seconds would be -3 m/s. Negative velocity indicates that the car is slowing down.

Explain why pulleys are in the lever family.
Answers
Answer:
The leverage or mechanical advantage of pulleys is less obvious, but you can "gang" multiple pulleys together into two sets (blocks) and run the ropes back and forth between the two sets to increase the number of lengths of rope running between them. One end of the rope is connected (fixed) to one of the blocks, and you get to pull on the other end after it is passed back and forth between the blocks of pulleys. This is sometimes called a block and tackle arrangement. With a hook on each side of the block set, you can move a heavy load much like levers do, by multiplying the force. You have to pull more rope just like you have to move a lever more on one side of the fulcrum as compared to the other. When you get all the rope pulled out that you can, you can not move the load anymore because you have become "two-blocked" which means the two blocks are together. Credits to: Moin Khan

(b) Compare this with the ratio of highest (20,000 Hz) to lowest (20 Hz) frequencies the ear can hear.
Answers
a). frequency = (speed) / (wavelength)
The speed of light is around 3 x 10⁸ m/s.
For 380 nm (violet light), frequency = (3 x 10⁸ m/s) / (380 x 10⁻⁹ m)
Frequency = 7.89 x 10¹⁴ Hz
For 760 nm (red light), frequency = (3 x 10⁸ m/s) / (760 x 10⁻⁹/s)
Frequency = 3.94 x 10¹⁴ Hz
The ratio is 2 .
That's 1 octave, or 0.3 of a decade.
b). The ratio of highest/lowest sounds is (20,000 Hz/20 Hz) = 1,000

Notice that a is made into a minus. It does not mean subtract. It means that the direction of the projectile and gravity must go in opposite directions. You will find that direction is a critically important consideration in physics.
Answer:
It'd take it 5.10 seconds
Explanation:
At the top of the launch, it is maximum height, h
formular derivation :
At maximum height, final velocity, v is zero
From first newtons equation:
\({ \sf{v = u + gt}}\)
v is the final velocity
u is the initial velocity
g is acceleration due to gravity
t is the time taken
but v is zero:
\(0 = u + gt \\ gt = u \\ t = \frac{u}{g} \)
since it is vertical motion, u = usin(theta), where angle is 90°
\({ \boxed{t = \frac{u \sin( \theta) }{g} }}\)
t is the time taken to reach the top of the launch:
substitute, taking g to be 9.8 m/s²
\(t = \frac{50 \times \sin(90 \degree) }{9.8} = \frac{50}{9.8} \\ \\ { \boxed{ \boxed{time = 5.10 \: seconds}}}\)
Eggs with a mass of 0.13 kg per egg and a specific heat of 3.27 kJ/kg. 0C are cooled from 30 0C to 10 0C at a rate of 630 eggs per minute. What is the rate of heat removal from the eggs in kW
Answers
The rate of heat removal from the eggs in kW is 89.25 kW.
Heat transfer problemTo calculate the rate of heat removal from the eggs, we need to determine the total amount of heat transferred and the time it takes for the transfer.
The amount of heat transferred can be calculated using the equation:
Heat transferred (Q) = mass (m) * specific heat (c) * temperature change (ΔT)
Given:
Mass of each egg (m) = 0.13 kg
Specific heat of eggs (c) = 3.27 kJ/kg·°C
Temperature change (ΔT) = 30 °C - 10 °C = 20 °C
Q per egg = 0.13 kg * 3.27 kJ/kg·°C * 20 °C
Q per egg = 8.514 kJ
Now, let's determine the total heat transferred per minute:
Rate of heat transfer = Q per egg * number of eggs per minute
Rate of heat transfer = 8.514 kJ/egg * 630 eggs/minute
Rate of heat transfer = 5,354.82 kJ/minute
Rate of heat removal in kW = 5,354.82 kJ/minute / 60
Rate of heat removal in kW ≈ 89.25 kW
Therefore, the rate of heat removal from the eggs is approximately 89.25 kW.
