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 .
Equation of line is y=mx+c
substitute y and x into y=mx+c,
7=1+c
c=6
hence, y=x+6
Answer:
The centripetal on the car will become 4 times when the velocity gets twice.
Explanation:
As we know that centripetal force on the car of mass m and moving with constant speed v given as
m=mass
v=velocity
r=radius of the circular arc
We are assuming that the mass of the both the car is same.
If the velocity of the car gets twice 2 v
The new centripetal force on the car
Therefore we can say that centripetal on the car will become 4 times when the velocity gets twice.
