Explanation:
initial height, yo = 2 m
initial velocity, u = 20 m/s
angle of projection,θ = 5 degree
distance of net = 7 m
height of net = 1 m
Let it covers a vertical distance y in time t .
Use Second equation of motion for vertical motion
As it hits the ground in time t, so put y = 0
Taking positive sign, t = 0.84 s
The ball travels a horizontal distance x in time t
X = 20 Cos5 x t
X = 16.76 m
As this distance is more than the distance of net, so it clears the net.
Let t' be the time taken to travel a horizontal distance equal to the distance of net
7 = 20 cos5 x t'
t' = 0.35 s
Let the vertical distance traveled by the ball in time t' is y'.
So,
y' = 2.008 m
So, it clears the net which is 1 m high.
It clears the net by a vertical distance of 2.008 - 1 = 1.008 m and horizontal distance 16.76 - 7 = 9.76 m
your welcome, and have a great day.
Answer:
the factor when the intensity of the sound increased the level by 12.2db is 16.60 times
Explanation:
The computation of the factor when the intensity of the sound increased the level by 12.2db
As we know that
10 increased its level by 10 dB
Here we used only 10dB as we are determining for 12.2dB
So
The factor should be
= 10^1.22
= 16.60 times
hence the factor when the intensity of the sound increased the level by 12.2db is 16.60 times
