Answer: the answer is B
Explanation: I just took the quiz :)
Answer:
Induced emf, 
Explanation:
The varying magnetic field with time t is given by according to equation as :
Where
are constant
Let 
is the emf induced in the loop as a function of time. We know that the rate of change of magnetic flux is equal to the induced emf as:
So, the induced emf in the loop as a function of time is 
. Hence, this is the required solution.
The volume of a cylinder is given by the formula v=pi r^2h, where r is the radius of the cylinder and h is the height.
<h3>What Does a Cylinder's Surface Area Look Like?</h3>
The overall area or region that the surface of a cylinder covers is referred to as its surface area. A cylinder's total surface area includes both the area of the curved surface and the area of the two flat surfaces because there are two flat surfaces and one curved surface. A cylinder's surface area is measured in square units like m2, in2, cm2, yd2, etc.
<h3>What is the cylinder's total surface area?</h3>
The sum of the curved surface areas makes up the cylinder's overall surface area.

By what i know i think that the answer would be A a homogeneous mixture.
I would say your answer is B- Some of the chemical energy from the batteries is converted into heat energy.
