1. A horizontal disc of mass M = 0.95 kg and radius R = 0.35 m rotates about a vertical axis with angular speed 3.6 rad·s-1. A piece of modelling clay of mass m = 0.30 kg lands vertically on the disc, attaching itself at a point r = 0.25 m from the centre. Find the new angular speed of the disc. please show work

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.​

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

a sonic boom is a loud boom that breaks the sound barrier
