Answer:
1.89 seconds
Explanation:
t = Time taken
u = Initial velocity = 9.6 m/s
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²
Time taken to reach maximum height is 0.97 seconds
So, the stone would travel 4.7 m up
So, total height ball would fall is 4.7+12.8 = 17.5 m
Time taken by the stone to travel 17.5 m is 1.89 seconds
Answer:
It is the amplitude.
Explanation:
The amplitude is the measure of the size of the disturbance from a wave, so half the distance from the trough and crest.
I think the answer is going to be C
Answer:
0.434 m
Explanation:
We are given that
Mass per unit length=
1 kg=1000 g
Tension=350 N
Fundamental frequency=f=440 Hz
We have to find the length you should make it.
We know that
Using the formula
l=0.434 m
Hence, you should make it 0.434 m long.
Answer:
air does not have a modulus of rigidity.
Explanation:
Since air is completely elastic medium, that is, it does not have a modulus of rigidity, therefore sound waves in air are longitudinal.
