Special cases: 23 initially stationary cart: suppose the second cart is initially stationary, v2i = 0 and the first cart comes in with a velocity v1i = vwhat are (v1f/v) and (v2f/v) in each of the following cases? type of collisionm 1=m 2m 1 ˃˃ m 2m 1˂˂m 2 head-on collision: suppose the two carts collide with velocity v, v1i = v and v2i = − v. what are (v1f/v)and (v2f/v) in each of the following cases? type of collisionm 1=m 2m 1 ˃˃ m 2 elastic? ? inelastic? ?

wavelength variability is the right one

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.​

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.
