Which ball size will bounce the highest?
Bounce height will not depend on the ball's radius. It will however depend on the material of the ball and the speed at which it hits the ground
Does the apparent focal spot size of a rotating anode tube depend upon the speed of anode rotation?
No, but as the rotation speed decreases, the maximum power loading in the spot decreases, so either the power must be turned down, or the spot made larger.
How does centripetal acceleration depend upon the object's speed and the radius of the circle?
The centripetal acceleration is equal to velocity squared over radius. a=v^2/r
How does a change in radius effect linear velocity?
For circular motion, linear speed = angular speed (in radians) x radius. How the radius affects speed depends what assumptions you make about the problem. For example, if you assume the radius increases but the angular speed does not, then of course the linear speed will increase.
If the radius of rotation and the mass being kept constant how does the centripetal force vary with the speed of rotation of the body?
Recall centripetal force = m v^2 / rAs m and r are found to be constants then centripetal force F is directly proportional to the square of the velocity of the body
Which ball size will bounce the highest?
Bounce height will not depend on the ball's radius. It will however depend on the material of the ball and the speed at which it hits the ground
Does the center of circle turn at the double speed as the outside if radius is double?
The centre of the circle does not turn at all: the axis of rotation goes through it.
How does the centripetal force with the speed of rotation of the body with constant mass and radius of rotation?
You can calculate the centripetal ACCELERATION with one of these formulae: acceleration = velocity squared / radius acceleration = omega squared x radius Acceleration refers to the magnitude of the acceleration; the direction is towards the center. Omega is the angular speed, in radians per second. To get the centripetal FORCE, you can use Newton's Second Law. In other words, just multiply the acceleration by the mass.
What is the formula for rotation in math?
In 2-dimensions, the formula for rotation through d degrees is [post-]multiplication by the matrix [cos(d) sin(d)] [-sin(d) cos(d)]
Why is the centrifugal acceleration decrease from the equator to the poles?
The relevant formula here is:centrifugal acceleration = omega squared x radiusomega (the angular speed) doesn't change in this formula (for the situation under consideration), but "radius", the distance from the axis of rotation, does.
Does the apparent focal spot size of a rotating anode tube depend upon the speed of anode rotation?
No, but as the rotation speed decreases, the maximum power loading in the spot decreases, so either the power must be turned down, or the spot made larger.
Which gear turns faster if the driving gear is smaller than the driven gear?
The answer does not depend on which gear is driving. Linear-wise, the two gears are meshed so the teeth are moving at the same speed. Rotation-wise, the smaller gear has smaller radius so it is "turning faster" in terms of RPMs.
How does centripetal acceleration depend upon the object's speed and the radius of the circle?
The centripetal acceleration is equal to velocity squared over radius. a=v^2/r
Number of bolt required to couple the flanges of a coupling depend upon factors?
Depends on motor load transmission, rotation of motor speed, frequency.
How does a change in radius effect linear velocity?
For circular motion, linear speed = angular speed (in radians) x radius. How the radius affects speed depends what assumptions you make about the problem. For example, if you assume the radius increases but the angular speed does not, then of course the linear speed will increase.

How does earth's varying orbital speed affect it's rotation?
The earth's orbital speed has no influence or effect on its rotation.
