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,
The answer is D. Chemical Energy
Sound waves<span> are longitudinal </span>waves<span>: the air moves back and forth along the same line as the </span>wave<span> travels, making alternate patterns of compressions and rarefactions. Bottom: Ocean </span>waves<span> are transverse </span>waves<span>: the water moves back and forth at right angles to the line in which the </span>wave travels<span>.</span>
Answer:
256 x 10³ Nm
Explanation:
Force on each of the charges of 8 C due to uniform electric field in x -y plane will be equal and opposite because one is positive charge and the other is negative charge. They will make a couple
Each of the forces of the couple will act in x - y plane and will be equal to
F = Q E = 8 X 8 X 10³
= 64 X 10³ N
Arm of the couple = 4 m
Moment of couple about z axis.
= 64 x 10³ x 4
= 256 x 10³ Nm.
