Apotter's wheel of radius 11 cm starts from rest and rotates with constant angular accel- eration until at the end of 35 s it is moving with angular velocity of 19 rad/s. what is the angular acceleration? answer in units of rad/s2.

angular acceleration = 0.54 rad/s/s

Explanation:

Initial angular speed of the wheel is ZERO as it starts from rest

final angular speed is given as

now we know that angular acceleration is rate of change in angular speed

here we have

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.
