Explanation:
The increase in the body temperature of pronghorn, the fastest North American animal, results from the chemical energy of the pronghorn converting into kinetic energy with efficiency less than 100%. The remaining energy is converted into heat energy. Thus, raising the temperature of pronghorn.
Due to the chemical energy it gains both kinetic and heat energy.
Answer:
<em>-2 units of charge</em>
Explanation:
charge on A = Qa = -6 units
charge on B = Qb = 2 units
if the spheres are brought in contact with each other, the resultant charge will be evenly distributed on the spheres when they are finally separated.
charge on each sphere will be = 
charge on each sphere =
=
= <em>-2 units of charge</em>
Answer:

Explanation:
A point charge Q is placed at the center of a cube of side l.
We need to find the flux through one face of the cube. Let the flux is
.
There are 6 faces in a cube.
According to Gauss's law, net flux is given by :

As there are 6 faces of a cube, flux through one surface is :

So, the flux through one face of the cube is
.
12 kWh.
The input energy = 36kWh divide by 0.75 = 48kWh
The lost energy = 0.25 x 48kWh = 12kWh
because 25% of input energy is lost to the surrounding.
