The surface temperature of our sun is about 5800 K, and the peak of its intensity curve is in the middle of the visible spectrum
amm1812

Explanation:

i expected to use Stefan's law of heat exchange but the value you gave aren't conclusive.

I should say that the temperature of the star should be close to that of the sun because of the similarity in the intensity curves

A circular track has a radius of 50m.What is the displacement?
stepladder [879]

The displacement of a moving object is the straight-line distance between the place it starts from and the place where it stops.

The displacement of anything moving along a circular track depends on how  far around it goes before it stops.  The greatest displacement it can possibly have is the diameter of the track ... 100m on this particular one ... because that's as far apart as two places on a circle can ever be.

The most interesting case is when the object goes around the circle exactly once.  Then it stops at the same place it started from, the distance between the starting point and ending point is zero, and after all that motion, the displacement is zero.

Process by which water vapor changes to a liquid
OverLord2011 [107]

The correct answer to the question is B) Condensation.

EXPLANATION:

Before coming into any conclusion, first we have to understand various phase changes.

There are various phase changes in which matter in one state is converted into matter in another state.

Evaporation: Evaporation is the thermal process of state change in which a liquid is converted into corresponding vapor state.

For instance, water to steam or vapor.

Condensation: Condensation is just the opposite process of evaporation. In this process, a substance in vapor phase is converted into liquid phase.

For instance, water vapor to liquid water.

The two processes that is Convection and radiation mentioned in the question are not phase changes. These two are different modes of heat transfer between substances.

Hence, the process by which water vapor changes to a liquid is called condensation.
