Answer:
How to find speed in physics
Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
Explanation:
Answer:
because of Gravity
Explanation:
The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.
Intensity of sound is defined by
So here we can say work done by us is stored in the form of energy of sound and that energy can be compared by the intensity of sound
So if we will do more work then the sound will have more energy and hence it will have more intensity
Now we know that intensity of sound is given as
so more is the intensity then more work which means the amplitude will be more
So answer will be
D. amplitude
I'd go with electricity source. Good luck!!
