Time taken by the water balloon to reach the bottom will be given as
here we know that
now by the above formula
now in the same time interval we can say the distance moved by it will be
so it will fall at a distance 15.7 m from its initial position
time=distance/speed
1.6/100 secs = 0.016secs=16millisecs
Answer:
The refraction of light at the surface of water makes ponds and swimming pools appear shallower than they really are. A 1m deep pond would only appear to be 0.75 m deep when viewed from directly above. When light emerges from glass or water into air it speeds up again.
Explanation:
B. so light can shine through it from below.
To find the horizontal distance multiple the horizontal velocity by the time. Since there is no given time it must be calculated using kinematic equation.
Y=Yo+Voyt+1/2at^2
0=.55+0+1/2(-9.8)t^2
-.55=-4.9t^2
sqrt(.55/4.9)=t
t=0.335 seconds
Horizontal distance
=0.335s*1.2m/s
=0.402 meters
