A boat of mass 1,300 kg that is moving at a speed of 6 m/s and a speedboat of mass 850 kg that is moving at a speed of 25m/s. What’s the total linear momentum of the boat and the speedboat?

coil wire, increase current, put iron inside the coil

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.​
