Astring is wrapped around a pulley of radius 0.05 m and moment of inertia 0.2 kg-m2. if the string is pulled with a force f , the resulting angular acceleration of the pulley is 2 rad/s2. determine the magnitude of the force f?

f = 8 N

Explanation:

from the question we are given the following values

radius of the pulley (r) = 0.05 m

moment of inertia (I) = 0.2 kg.m^{2}

angular acceleration (∝) = 2 rad/sec

force (f) = ?

we can apply  f x r = I x ∝ to get our force

f x 0.05 = 0.2 x 2

0.05f = 0.4

f = 8 N

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.​
