Answer:
Explanation:
The torque applied on an object can be calculated by the following formula:
where,
T = Torque
F = Applied Force
r = radius of the wheel
For car wheel:
For truck wheel:
Dividing both:
for the same force applied on both wheels:
where,
rt = radius of the truck steering wheel = 0.25 m
rc = radius of the car steering wheel = 0.19 m
Therefore,
Power dissipated across any resistance is given by
now it is given that when one resistance of value 3 ohm connected the power dissipated is 4 Watt
now another identical resistance of same value is connected then the current will reduce to half of its initial value.
now power across any one resistance is given by
So now we will have
So now the power will become 1/4 times of initial power
So now the power will be
