HEL 4. A 120 kg lineman moving west at 2 m/s tackles an 80 kg
football fullback moving east at 8 m/s. After the collision, both
players move east at 2 m/s. Draw a vector diagram in which
the before- and after-collision momenta of each player is
represented by a momentum vector. Label the magnitude of
each momentum vector.

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.​
