The equation to be used to
calculate the heat release when solid melts is the enthalpy of melting. It is
represented as H
= mCpT where H is the heat
released after phase change, m is the mass of the substance, Cp is the specific
heat capacity of the substance and T
is the change in temperature.

14. The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere "behaves" over relatively long periods of time
I hope I helped you with number 14, I can't answer number 15 sorry :(
The period of a mass-spring system is:
T = 2π
T = period, m = mass, k = spring constant
Given values:
T = 8π s
k = 2 N/m
Plug in and solve for m:
8π = 2π
= 4
m/2 = 16
m = 32 kg
