In a recent study of how mice negotiate turns, the mice ran around a circular 90∘ turn on a track with a radius of 0.20 m. The maximum speed measured for a mouse (mass = 18.5 g) running around this turn was 1.59 m/s. What is the minimum coefficient of friction between the track and the mouse's feet that would allow a turn at this speed?

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.​

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
