shutvik [7]
The moisture in the freezer will freeze due to the cold temperature, and form a layer of ice (the water molecules expand and solidify).

Usimov [2.4K]

Answer:

a) 70,560 J

b) 88.2 N/m

Explanation:

The spring potential will equal the change in gravity potential

PS = PE = mgh = 80(9.8)(100 - 10) = 70,560 J

PS = ½kx²

k = 2PS/x² = 2(70560)/(100 - 50 - 10)² = 88.2 N/m
