<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.

The magnitude is 167.6cm and the angle (relative to the floor) of the displacement of p is 32.5 degree.
<h3>
What is displacement ?</h3>
A displacement is a vector in geometry and mechanics that has a length equal to the shortest distance between a point P's initial and final positions. It calculates the length and angle of the net motion, or total motion, in a straight line from the starting point to the destination of the point trajectory. The translation that links the starting point and the ending point can be used to spot a displacement.
A point's ultimate location in relation to its original position, or a displacement, can also be defined as a relative position. The instantaneous velocity of an object is the rate at which the displacement changes as a function of time when studying motions of objects throughout time.
Explanation:
a)
height = 2*r =2*45 cm = 90 cm
y = 1/2 * circumference
=1/2 * 2*pi*r
= pi*r
= pi*45
= 141.4 cm
displacement =sqrt ( height^2 + y^2)
= sqrt (90^2 + 141.4^2)
= 167.6 cm
Answer: 167.6 cm
b)
angle ,x = atan (height/y)
= atan (90/141.4)
= 32.5 degree
Answer: 32.5 degree

Answer:
0.9 cm
Explanation:
The computation in the increase in the length of the joined rod is shown below:
As we know that
Increase in length = increase in the length of aluminum rod + increase in The length of steel rod
= 0.9 cm
We simply added the length of aluminium rod and length of steel rod so that the length of the joined rod could come and the same is to be considered
Using a basking spot so some sort of heated object, for example heating lamp or heating pad.
