Which of the following relationships is true?
A
For each additional kilogram of mass, the force of the sphere doubles.
B
The force of the spheres decrease as the mass of the spheres increase.
С
The acceleration of the spheres is constant, even when the mass and force change.
D
The mass and force of the spheres will remain constant if their acceleration is constant.

Two nitro no2 groups are chemically bonded to a patch of surface. they can't move to another location on the surface, but they can rotate (see sketch at right). it turns out that the amount of rotational kinetic energy each no2 group can have is required to be a multiple of ε, where =ε×1.010−24 j. in other words, each no2 group could have ε of rotational kinetic energy, or 2ε, or 3ε, and so forth — but it cannot have just any old amount of rotational kinetic energy. suppose the total rotational kinetic energy in this system is initially known to be 32ε. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ε. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.
