The material is at its phase change temperature and the thermal energy is going to change the phase instead of increase the temperature.
<h3>
What is latent heat?</h3>
Latent heat is defined as the thermal energy absorbed or released during a phase change of a substance.
Latent heat can also be explained as the energy in hidden form which is supplied or extracted to change the state of a substance without changing its temperature.
From the above explanation, we can conclude that, the material is at its phase change temperature and the thermal energy is going to change the phase instead of increase the temperature.

Answer:
A) False
B) False
C) True
D) True
E) True
Explanation:
A) At the critical angle, no light is reflected and all light is transmitted: This statement is false because critical angle has nothing to do with whether all light is transmitted.
B) During refraction, the ray that travels through the second medium is called the incident ray: Statement is False because the ray in the second medium is called refracted ray.
C) The angle of refraction is measured from the perpendicular to the boundary between two materials: Statement is true.
D) The speed of light in a medium is always less than the speed of light in a vacuum: Statement is true because speed of light in vacuum is approximately 300,000 km/s and no other light can go higher than that.
E) The virtual image of a pencil in a glass of water is closer to the viewer than the actual pencil: Statement is true.
Thickness, length, and temperature
Explanation:
First, we will calculate the torque because of the rope wrapped around the drum as follows.
torque1, =
= 3.496 N m
Now, we will calculate the torque because of the rope around the core as follows.
torque2, =
= 3.046 N m
(Since, we are provided with any figure which means that the torque can act either in the same direction or in the opposite direction.)
So, if the torque is acting in the same direction then,
torque = torque1 + torque2
= (3.496 + 3.046) N m
= 6.542 Nm
And, if the torque is acting in the opposite direction then,
torque = torque1 - torque2
= (3.496 - 3.046) Nm
= 0.45 Nm
