Answer:
You are correct, it is (3) the ball is in motion as it rolls down the slope.
Explanation:
For number 1 it would make sense because how would the student be in motion if he is just standing there throwing the ball down the slope, not himself.
For number 2 still wouldn't make so much sense since we are talking about the ball being in motion not the student.
For number 3 it seems the most reasonable because the ball is in motion as it is rolling down the slope.
For number 4 it doesn't make sense for a ball to lose its shape just by rolling, also even if you're like: "oh, but what if its leaking air or has a hole??" well easy then. It STILL wouldn't matter because in the sentence it never specifies it has a "hole" or is "leaking air" therefore this answer is wrong.
YOUR ANSWER IS number 3.
Answer:
Q
Explanation:
To know which symbol defines the wavelength, we must know the definition of wavelength.
Wavelength can be defined as the distance between two successive crests (i.e the highest part) or troughs (the lowest part) of a wave.
Considering the diagram given above, Q shows the distance between two successive crests (i.e the highest part) of the wave. Therefore, Q is the wavelength of the wave given in the diagram above.
Resistance = (voltage) / (current)
Resistance = (12v) / (0.33 A)
Resistance = (12/0.33) ohms
<em>Resistance = 36.4 ohms</em>
