1) Which of the following has the greatest momentum? Explain.
v = 5 m/s
m = 1.2 X 10 kg
m = 1800 kg

m=1800 kg has the   greatest momentum

Explanation:

Linear momentum is defined as the product of mass and velocity of a body. It is directly proportional to mass and velocity and is given by the expression

P=mv

where P denotes linear momentum,m denotes mass and v denotes velocity.

given that

velocity of both objects is v=5 m/s

Mass of the first object m=

Mass of the second object m=1800 kg

velocity of both objects is same. The second object has higher mass than first.

When mass increases, momentum increases with it.

Thus the second object with m=1800 kg has higher momentum than first.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
