Answer:

Explanation:
Here we know that initial temperature of ice is given as

now the latent heat of ice is given as

now we also know that the mass of ice is

so here we know that heat required to change the phase of the ice is given as

Answer:
The higher the spring constant, the greater the elastic potential energy.
Explanation:
Displacement is the shortest distance between two points. Displacement is used to calculate vector quantities such a velocity, force, acceleration, etc.
Here, Maria drove to the store and then to work this means that her total displacement will be the minimum distance between her initial point and her work place.
Hence, the minimum distance between her initial point and her work place is her total displacement.
