The given question is incomplete. The complete question is:
Estimate the volume of each ball. Use the formula where v is the volume and r is the radius. record the volume in table A of your student guide. The radius of the tennis ball is 2.1 cm and the radius of thr golf ball is 2.0 cm. What is the estimated volume of the table tennis ball in What is the estimated volume of the golf ball in
Answer: Volume of the tennis ball is and Volume of the golf ball is
Explanation:
We have to find the Volume of tennis ball and golf ball by using the formula
Radius of the tennis ball = 2.1 cm
Radius of the golf ball =2.0 cm.
Putting the value of radius in the formula , we get:
Volume of the tennis ball =
Volume of the golf ball =
Volume of the tennis ball is and Volume of the golf ball is
There could as smaller objects have more inertia. Mass is a measure of an objects in Harsha. Objects with greater mass have a greater in Inertia yet it’s still maintains the same amount of inertia as usual. It still has the same tendency to resist changes in its state of motion. So yes it is possible that there could ever be a situation where a small sports car would have more inertia than a big bus. :)
Answer:
The correct option is (b).
Explanation:
Given that,
At the top of the hill, the kinetic energy is E and the gravitational potential energy is 3E.
We need to find the kinetic energy of the car on the ground.
We know that,
Mechanical energy = kinetic energy + potential energy
According to the law of conservation of energy, the total mechanical energy is conserved.
It means, when it coasts down to ground level, the kinetic energy is same as that on the top of the hill. Hence, the required kinetic energy on the ground is equal to 3E.
Take your 23.4 cm^2 .
Multiply it by
(1 meter / 100 cm) ^2 .
If you handle all of the units correctly,
you'll end up with 0.00234 m^2 .
1 pound ≈ 0.4536 kg
170 pounds ≈ 170 * 0.4536 kg
≈ 77.112 kg
