A math professor cycles around a corner which is banked (inclined downwards towards the center of the radius of curvature). The centripetal force that causes the bike to go round a bend in the road is usually provided by friction. This road is very icy, however. Could the force required to turn the corner be provided if the friction coefficient between the bikes tires and the road goes to 0.01? Find the range of velocities required by the bike if the radius of curvature of the curve is 120 m and the road is banked at 10o to the horizontal.

Explanation:

Given that,

max speed for cycle for safe turning on the corner

min speed for cycle for safe turning on the corner

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.​
