Explanation:
A wall that is acted upon by a force of 20N does not move suggests that no work has been done on the wall.
Work done is the force applied to move in the direction of the applied force.
Work done = force x distance.
Since the distance is 0, the work done on the body too is zero.
Work is only done when forces moves a body through a given distance.

Answer:
they stay shifted the same amount to the red
Explanation:
Redshift is given by
Where,
= Wavelength observed
= Wavelength emitted
Also
Transverse redshift is given by
v = Velocity of object
c = Speed of light = 
So, if the velocity is constant the redshift remains the same
Answer:
The acceleration will be 140 meter per second
Explanation:
Force F = mass m × acceleration a
If F = 42 N and m = 0.30 kg
Then acceleration a = F/m
a = 42/0.30
a = 140 m/s
