In both cases shown above, a block of mass M is set on a rough table. The block is connected to a string that passes over an ideal pulley. In Case 1, the free end of the string is connected to a hanging object of mass m = 10 kg. In Case 2, the hanging object is removed and a person grabs the free end of the string and pulls with a constant force equal to 98 N, the weight of the hanging object in Case 1. In both cases, the block is released from rest the same distance from the right edge of the table.

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.​

radiation

explanation:

heat is transmitted by radiation

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
