Two iron weights, one twice the mass of the other, are dropped from the top of a building. Compared with the lighter weight, the twice as heavy weight will hit the ground with (2 points) a
half the momentum

b
the same momentum

c
twice the momentum

d
four times the momentum

The number to the right of an element's symbol (ex. c-12) identifies the of an isotope.

Why does asexual reproduction result in offspring with identicle genetic variation

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
