<h3>What is a heating curve?</h3>
The heating curve is a representation of temperature change for a body with time as shown on cartesian axes.
The point A represents the steady increase in the temperature of the solid. The point B shows the point of fusion, at this point, the solid is transformed into liquid. The point C shows the temperature rise with time as the liquid is heated. The point D shows the process of vaporization which converts the liquid to gas. The point E shows when the substance now exists in the gas phase.

Answer:
The wave produced is a standing wave.
y' = [2ymax - kx] cos wt.
y max is maximum displacement, k is angular wave number, x is equal to the length L, w is angular frequency, t is time.
The time taken for the wave to travel to the ceiling and get reflected is given as:
t = 1/f = (2L)/nv. Where n =, 1,2,3, .... and v is wave speed, f is wave frequency.
Answer:
B is the answer because it's the closest to the sun, so it has a smaller path.
Answer:
I'm not sure, I think it's near the northern hemisphere.
Answer:
1470Joules
Explanation:
Workdone = Force * distance
Since the worker pushes the crate up the 3m ramp. The distance covered is 3m
Force = Mass * Acceleration due to gravity
Force = 50*9.8
Force = 490N
Workdone = 490 * 3
Workdone = 1470Joules
Hence I did 1470Joules of work
