The force here is the acceleration. This force is used to decrease the velocity of the object in order to slow it down. This means that the direction of the force must be opposing the direction of motion of the object.
Based on this,
If an object is travelling east with a decreasing speed, the direction of the object's acceleration is west.
The statement that can be used to answer this question is:
"If the cylinder is brought higher then, its temperature when brought down becomes higher because a greater amount of potential energy is converted to thermal energy."
The potential energy is converted to thermal energy when the object is released the velocity becomes higher because of the acceleration due to gravity.
No the acceleration of gravity on earth is still 9.8ms-2 unless he was on a different planet
Answer:
The sine waves of the two waves should look the same.
Explanation:
The sine wave formula for a sound wave is given as
y = A sin[2πft + θ]
where
y = The displacement of the wave at time t.
A = amplitude or maximum displacement of the wave during its progression.
t = time
f = frequency of the wave
θ = phase angle/phase shift of the wave which is normally 0 for sound waves
From this information,
It is evident that it is the frequency and time that dictate the exact motion of the wave or behaviour of the waveform. The amplitude only dictates the extent of the wave.
And if the frequency of 2 waves A and B are similar, then even a very different Amplitude cannot change the fact that the two waves will behave similarly, have the same sine curve and have the same movements as the time of progression increases.
Even if the phase angle isn't zero, whatever it is, will not change the fact that the two waves will appear similar to each other, only separated by that phase angle.
Hence, the two waves will look very similar with only the amplitude that shows the extent of displacement, different.
Hope this Helps!!!
The answer is A
