Answer:
Explanation:
Given
Train travels towards south with a velocity if
Rain makes an angle of with vertical
If an observer sees the drop fall perfectly vertical i.e. horizontal component of rain velocity is equal to train velocity
suppose is the velocity of rain with respect to ground then
Therefore velocity of rain drops is 27.36 m/s
Frictional force between the object and the floor=5 N
Explanation:
power= 50 W
velocity= 10 m/s
power= force * velocity
50=F * 10
F=50/10
F=5 N
Thus the force of friction= 5 N
The body senses whether it is upright or lying down or whether it is moving or standing still through the vestibular system, which is in the upper portion of the inner ear.
That would be true because a solid object can cast a shadow
