When we see the trees from a moving train, their position is changing with respect to us. Hence they appear to be moving. On the other hand the position of co-passengers is not changing with respect to us, hence they appear to be stationary.
Solution:
Let the speed of the train by x km/hr
And the time taken by the train be ‘y’ hrs
Distance traveled by the train is x.y = xy
Case I
If the train would...
(a) 35000 N (b) 1.944 m/s2 (c) 15552 N
(a) Force exerted by the engine, F = 40000 N
Frictional force offered by the track, Ff = 5000 N
Net accelerating force, Fa...
Deserts are vast stretches of sand where the falling rain water immediately percolates downwards in the spaces between sand particles. Due to this he did not see streams of water...
This is because of scattering of light. Light from the Sun near the horizon passes through larger distance in the earth’s atmosphere before reaching our eyes. So, most of the...
(a) longitudinal stationary waves
EXPLANATION:
An organ pipe open at both ends contains sound waves which are longitudinal waves, so the option (c) and (d) are not true. When the waves enter...
