Answer:The mass of ball B is 10 kg.
Explanation;
Mass of ball A =
Velocity of the ball A before collision:
Velocity of ball A after collision=
Mass of ball B=
Velocity of the ball B before collision:
Velocity of ball B after collision=
The mass of ball B is 10 kg.
Answer:
Δu=1300kJ/kg
Explanation:
Energy at the initial state
Is saturated vapor at initial pressure we have
Process 2-3 is a constant volume process
The overall in internal energy
Δu=u₁-u₃
We replace the values in equation
Δu=u₁-u₃
Δu=1300kJ/kg
heat from water goes into air in ball
air expands
ping goes the dent
