If it takes cool air and passes it through the heat source using a fan or blower, the type of heat transfer is convection heat transfer.

<h3>What is heat transfer by convection?</h3>

Convection is the transfer of heat from one place to another due to the movement of fluid.

During heat transfer by convection, cold air replaces hot risen air.

Thus, if it takes cool air and passes it through the heat source using a fan or blower, the type of heat transfer is convection heat transfer.

A circular loop (radius of 20 cm) is in a uniform magnetic field of 0.15 T. What angle(s) between the normal to the plane of the
Wittaler [7]

Answer:

The angle other than 90 degrees would result in magnetic flux of non zero magnitude.

Explanation:

The magnetic flux through a given closed area is equal to \underset{B}{\rightarrow}.\underset{A}{\rightarrow}.

    Where \underset{B}{\rightarrow} is the magnitude of magnetic flux through loop .

                \underset{A}{\rightarrow} is the area vector of the given loop .

      We know that \underset{B}{\rightarrow}.\underset{A}{\rightarrow} = \left | A \right |\left | B \right |\cos \theta,

 Where \theta is the angle made by magnetic field with area vector.

   Area vector of a closed loop is always normal to the plane of the loop .

So from above equation we can deduce that

                  \theta = \cos^{-1}\frac{\phi }{\left | A \right |\left | B \right |}      

      \phi is the magnitude of magnetic flux which is non zero when \theta not equal to 90 degrees.

When water in clouds undergoes condensation, it can lead to?
olga_2 [115]
It will lead to rain. I know this because as the clouds move over water sources like oceans, lakes, and rivers, the water evaporates and rises. The water then liquefies into little water droplets. As the cloud moves over more water the droplets get scrunched up and get bigger over time and soon they get heavy and gravity pulls the droplets down to earth as rain. The End.

if the force of friction is acting on the sliding crate is 100 N how much force will be applied to maintain a constant velocity?
djverab [1.8K]
"Constant velocity" means zero acceleration, which means zero net force.  So there must be100N pulling on the crate to cancel the 100N of friction force.
