4. substance in a solution that is dissolved
; f. solute
5. substance in a solution that is does the dissolving

Answer: A. Superconductor
Explanation:
Ground-Fault Circuit Interrupter
, Fuse, Circuit Breaker cause the circuit to break when high amount of current flows through it; thereby protecting any electrical accidents. A superconductor has zero resistance. It gives an easy path for an amount of electricity to flow through it. Thus, it would not prevent electrical accidents.
Answer:
Explanation:
= Vacuum permeability =
= Radius of loop = 15 cm
= Current in loop = 11 A
= Radius of coil = 0.76 cm
N = Number of turns of coil = 66
= Current in coil = 1.9 A
Magnetic field is given by
Magnitude of magnetic field produced by the loop at its center is .
Torque is given by
Magnitude of torque on the coil due to the loop is
The addition of heat energy to a
system always causes the temperature of that system to increase. This is always
true because you are adding heat of a substance to increase its temperature. For example, you are going
to drink a cup of coffee. And you wanted it hot to boost your attention. So you
have to use hot water. In order for your water to become hot or warm, you need
boil it in a kettle. Note that you are going to use an electric stove. The
electric stove gets it energy from the source giving it a hotter temperature to
the water in the kettle. You are applying heat energy to warm the water. So,
the statement is true.
A computer can show you how it is done and how they got to that solution while a graphing calculator can only show you the solution.
