Answer:
the quantity of matter contained in a body is called mass .si unit of mass is kilogram.weight is effected by gravity but mass is not effected by gravity.
Answer:
75
Explanation:
V=IR
V=75
I=1
So
75=1R. Divide both side by 1
R=75
We use the voltage division problem between the load resistance, amplifier output resistance as
.
Here,
is the output voltage,
is the amplifier voltage,
is the load resistance and
is the amplifier output resistance.
Therefore,
.
Thus, the amplifier output resistance is
.
