The quantity of matter in a body regardless of its volume or of any forces acting on it.
Answer:
it is a force
Explanation:
a force is a push or a pull
The velocity is 60 because you divide your distance by your time (240÷4=60)
Answer:
A spinning turbine can generate electricity only in the form of an alternating current.
Answer:
If the frequency of the source is increased the current in the circuit will decrease.
Explanation:
The current through the circuit is given as;

Where;
V is the voltage in the AC circuit
Z is the impedance

Where;
R is the resistance
is the inductive reactance
= ωL = 2πfL
where;
L is the inductance
f is the frequency of the source
Finally, the current in the circuit is given as;

From the equation above, an increase in frequency (f) will cause a decrease in current (I).
Therefore, If the frequency of the source is increased the current in the circuit will decrease.
