You end up pulling your little brother to the top of the hill. Determine the angle of the incline if the coefficient of friction is still 0.34 and your brother reaches a speed of 23m/s from rest over a distance of 30m

a person with a mass of 106kg has a weight of 1060n

momentum of soft ball three times less than baskey ball

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
