Yes it is work. Your brother may already be moving, but pushing him will make him go faster.
To calculate the work done, we need to consider the force applied by the girl minus the force of friction. The net force is 300N - 200N = 100N. Work done = force x distance. Therefore, the work done is 100N x 750m = 75,000 joules.
No work is done when pushing on a wall because work is defined as force applied over a distance in the direction of the force. When pushing on a wall, the wall does not move, so there is no displacement in the direction of the force, hence no work is done.
Examples of forces at work include gravity pulling objects toward the Earth, tension in a stretched rubber band, a person pushing a box across the floor, and the magnetic force between two magnets. These forces can cause objects to move or change shape.
If they were healthy and could work, they would be put to work. Otherwise they were likely to be terminated. In a talk from a survivor, the man said that his father, himself and his little brother were sent one way and mother was sent the other. They pushed the little brother over to be with the mother, thinking he would be safer there. The mother and younger brother were never seen again.
Fuse.
when you act a force on it or on the object
I think yes
It depends on how old he is. If he is older you could give him video games to play and if they are younger, food tends to work.
Does your brother work in a hospital? is the correct sentence.
No, pushing against a wall does not result in any work being done. Work is only done when a force causes an object to move in the direction of the force, so if the wall does not move, no work is done.
it is the work of pushing out the fetus
Pushing on a wall does not result in work being done in the physics sense, as work requires displacement of an object in the direction of the force. The wall does not move, so no work is done on it. However, your muscles are still expending energy to push on the wall.
