A.) LUNAR MARIA..............
Answer:C
Explanation:
When a constant horizontal force is applied to the box, box started moving in the horizontal direction such that it moves with constant velocity
Constant velocity implies that net force on the box is zero
i.e. there must be an opposing force which is equal to the applied force and friction force can serve that purpose.
So option c is the correct choice.

Answer:
The wavelength of the light is .
Explanation:
The band separation for a light wave of wavelength is given by
where is the slit separation, and is the distance to the screen.
Solving the above equation of wavelength we get:
Now, in our case
,
and ;
therefore,
which is the 2nd choice from the options given.
Answer:
<h2>94,550.4 J</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
We have
PE = 134 × 9.8 × 72 =94,550.4
We have the final answer as
<h3>94,550.4 J</h3>
Hope this helps you
