A diagram shows how gravity on Earth works on an object located in different spots in a seaside community. Where is gravity between Earth and an object the strongest? (1 point)
when the object is on the highest branch of a pine tree
when the object is on top of a nearby mountain
when an object is at sea level
when the object is on top of a telephone pole

Nuclear fusion is the source of energy for stars. besides hydrogen, which other element is most likely also common in stars?

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.

Which of the following best supports the concept that genetic information is passed on to offspring from both of their parents, not just one?
