Answer:

Transverse motion does not produced a doppler effect for a star. As, the doppler effect are occurred when the object are emitting light either in the direction towards the observer or moving away. The various astronomical objects are moving and the observer observed the blue wavelength of the light.

Doppler effect in the star is the process when the observer moves towards the star then it seems like the star move towards the observer.

Wewaii [24]

Given :-

An elevator is moving vertically up with an acceleration a.

To Find :-

The force exerted on the floor by a passenger of mass m .

Solution :-

As the man is in a accelerated frame that is non inertial frame , we would have to think of a pseudo force .

The direction of this force is opposite to the direction of acceleration the frame and its magnitude is equal to the product of mass of the concerned body with the acceleration of the frame .

For the FBD refer to the attachment . From that ,

$\implies Weight_{apparent}= mg + ma$

Hence option d is correct choice .

I hope this helps .

To solve this problem we will apply the concepts related to electric potential and electric potential energy. By definition we know that the electric potential is determined under the function:

$V = \frac{k_e q}{r}$
