Answer:
 , assuming that the gravitational field strength is
, assuming that the gravitational field strength is  .
. 
Explanation:
Notice that both the speed and the direction of motion of this block are constant. In other words, the velocity of this block is constant.
By Newton's Second Law, the net force on this block would be  . External forces on this block should be balanced. Thus, the magnitude of the (downward) weight of this block should be equal to the magnitude of the (upward) force that the boy applies on this block.
. External forces on this block should be balanced. Thus, the magnitude of the (downward) weight of this block should be equal to the magnitude of the (upward) force that the boy applies on this block.
Let  denote the mass of this block. It is given that
 denote the mass of this block. It is given that  . The weight of this block would be:
. The weight of this block would be:
 .
.
Hence, the force that the boy applies on this block would be upward with a magnitude of  .
.
The mechanical work that a force did is equal to the product of:
- the magnitude of the force, and 
- the displacement of the object in the direction of the force. 
The displacement of this block (upward by  ) is in the same direction as the (upward) force that this boy had applied. Thus, the work that this boy had done would be the product of:
) is in the same direction as the (upward) force that this boy had applied. Thus, the work that this boy had done would be the product of:
- the magnitude of the force that this boy exerted,  , and , and
- the displacement of this block in the direction,  . .

B. the distance the star is from Earth
Explanation:
The apparent magnitude of star is a function of its distance from the earth. It is one of the physical properties that is used to study a star. 
The apparent magnitude of a star or other astronomical bodies is a measure of their brightness as seen from a location on the earth. 
The apparent magnitude of a star depends on: 
- Distance of the star from the location on earth. 
- luminosity of the star
- the particles along the part of the star and earth that cuts off the light the earth receives.

Answer: no
Explanation:
because the object is moving downwards so it will be  called decceleration . which is the opposite of acceleration .
