The free fall of the phone is an uniformly accelerated motion toward the ground, with constant acceleration equal to
So, assuming the downward direction as positive direction of the motion, since the phone starts from rest the distance covered by the phone after a time t is given by
And if we substitute t=2.7 s, we find the distance covered:

Answer:
Explanation:
Given
mass of ice
Final temperature of liquid
Specific heat of water
Latent heat of fusion
Latent heat of vaporization
Suppose M is the mass of steam at
Heat required to melt ice and convert it to water at
Heat released by steam
and
must be equal as the heat gained by ice is equal to Heat released by steam
