In the lab setup above, block 1 is being pulled across a smooth surface by a light string connected across a pulley to a falling block 2. The pulley has negligible mass and friction. Students measure the mass of each block, the distance from A to B , and the speeds of the block on the surface at points A and B . Which of the following hypotheses can be tested with this setupAs block 1 moves from point A to point B, the work done by the tension on block 1 is equal to the kinetic energy of block 1 at point B. As block 1 moves from point A to point B, the work done by the tension on block 1 is equal to the kinetic energy of the two-block system when block 1 is at point B. As block 1 moves from point A to point B , the work done by gravity on block 2 is equal to the kinetic energy of block 1 at point B. As block 1 moves from point A to point B, the work done by gravity on block 2 is equal to the change in the kinetic energy of the two-block system. As block 1 moves from point A to point B, the work done by the tension on block 2 is equal to the kinetic energy of block 2 when block I has reached point B.

As block 1 moves from point A to point B, the work done by gravity on block 2 is equal to the change in the kinetic energy of the two-block system.

Explanation:

As block 2 goes down , work is done by gravity on block 2 . This is converted

into kinetic energy of block 1 and block 2 . Work done by gravity is mgh which can be measured easily . kinetic energy of both the blocks can also be measured.  

jupiter

explanation:

it is so massive and has such a strong gravitational pull its likely prevented the formation of a planet between itself and mars in the asteroid belt

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
