Consider the four spheres. As illustrated by the diagram, we would expect spheres A - C to be attracted to sphere D. Sphere D has
the greatest gravitational force because as represented here, it

A. is the most massive
B. has a negative charge.
C. is composed of metal.
D. is on top of the other three

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.

Me with this and you will be marked brainliest

1700 j of energy is lost from 0.14 kg object , the temperature decreases from 50°c to 45°c what is the specific heat of this object, amd what is the material ?
