Answer:
m = 40.88 g
Explanation:
Given data:
We know that Ice at zero degree celcius convert into liquid form by observing heat
latent heat of fusion = 79.5 cal/g
heat required or relaesed to convert 50 gram of water at 65 degree c to zero degree celcius
let mass of ice is m
where 1 cal/g os specific heat of water
solving for m
m = 40.88 g
The skater's final angular speed is equal to 12 rad/s.
When implemented to angular momentum, the regulation of conservation means that the momentum of a rotating item is no longer exchanged until some form of external torque is carried out. Torque, in this sense, can check with any outside pressure that acts upon the object for the purpose to twist or rotate.
The law of conservation of angular momentum states that once no external torque acts on an item, no trade of angular momentum will occur. The angular momentum of a machine is conserved as long as there may be no net external torque performing on the machine.
In angular kinematics, the conservation of angular momentum refers back to the tendency of a device to keep its rotational momentum inside the absence of outside torque. For a round orbit, the system for angular momentum is (mass) ×(pace) ×(radius of the circle): (angular momentum) = m × v × r.
