Answer:
The work done by gravity is 784 J.
Explanation:
Given:
Mass of the block is, 
Height to which it is raised is, 
Acceleration due to gravity is, 
Now, work done by gravity is equal to the product of force of gravity and the distance moved in the direction of gravity. So,
Force of gravity is given as the product of mass and acceleration due to gravity.
. Now,
Therefore, the work done by gravity is 784 J.

Answer:
Without the powers of the Flash, no. ... This would allow the Flash to force his molecules through the object he wants to phase through by moving them through the gaps in the object's atoms. It would probably cause more damage to the body or the object being phased through than shown in the comics/show, but it can be done.
