Answer:
is the drop in the water temperature.
Explanation:
Given:
- mass of ice,
- mass of water,
Assuming the initial temperature of the ice to be 0° C.
<u>Apply the conservation of energy:</u>
- Heat absorbed by the ice for melting is equal to the heat lost from water to melt ice.
<u>Now from the heat equation:</u>
......................(1)
where:
latent heat of fusion of ice
specific heat of water
change in temperature
Putting values in eq. (1):
is the drop in the water temperature.
Answer:
can u send a picture to identify it
Explanation:
sorry I just need point:/
Explanation:
The initial kinetic energy for both blocks is zero. Let and . So using the conservation law of linear momentum, we can write
or
The final kinetic energies for the two masses are
Therefore, the ratio of their kinetic energies is
