The four balls in the diagram are made of the same material and are solid. Why is the force of gravity between the balls in Pair 2 greater than the force of gravity between the balls in Pair 1? Sc.8.E.5.4Immersive Reader (4 Points)

The balls in Pair 1 have more rolling friction than the balls in Pair 2.

The balls in Pair 2 have a greater mass than the balls in Pair 1.

The balls in Pair 1 have more magnetic force than the balls in Pair 2

The balls in Pair 2 are closer together than the balls in Pair 1.

In atoms, the electron carries a negative elementary or unit charge; the proton carries a positive charge. the two types of charge are equal and opposite. in an atom of matter, an electrical charge occurs whenever the number of protons in the nucleus differs from the number of electrons surrounding that nucleus.

The figure is missing but we can answer anyway.the correct answer is "releasing the string". in fact, when the person is holding the bow and the arrow, the kinetic energy of the arrow is still zero (because the arrow is not moving). the moment the arrow is released, it acquires a velocity v, so its kinetic energy will become different from zero: where m is the mass of the arrow and v its velocity.  all the other options, instead, do not increase the kinetic energy of the system: -  pulling farther back on the string : this will just increase the elastic potential energy of the system-  holding the arrow higher: this will increase the gravitational potential energy of the system (which is given by u=mgh, where h is the height above the ground)-  decreasing the mass of the arrow: this will decrease the gravitational potential energy of the system (which is given by u=mgh, where m is the mass)
