What is the heat energy required to change the temperature 2.5kg of ice at -10°C to ice at 0°C?​

This is the number of complete movements of a wave per second.

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?
