How is the radius of rotation related to the centripetal force and angular velocity?
Assuming that angles are measured in radians, and angular velocity in radians per second (this simplifies formulae): Radius of rotation is unrelated to angular velocity. Linear velocity = angular velocity x radius Centripetal acceleration = velocity squared / radius Centripetal acceleration = (angular velocity) squared x radius Centripetal force = mass x acceleration = mass x (angular velocity) squared x radius
What is a circle with a little circle in it called?
An annulus. Area = pi (R2 - r2) when R is radius of larger circle and r is radius of smaller circle.
What will be the velocity of a satellite which is revolving around the earth in a circular orbit the radius R if the radius is increased from R to RR what will be the velocity?
the velocity will be velocity divided by square root of 2
Relation between linear velocity and angular velocity?
linear velocity= radius* angular velocity
How do you convert radians per second to meters per second?
the tangential velocity is equal to the angular velocity multiplied by the radius the tangential velocity is equal to the angular velocity multiplied by the radius
How does a gravitational field work?
A gravitational field works by creating a velocity profile that masses in the field follow. For example the Earth has a velocity of 29814m/s at the radius of 150Gigameters from the Sun. This This velocity V= Squareroot[GM/r] this velocity is independent of the Earth and just depends on the Gravitational field of the Sun. The Direction of the Velocity is angled to maintain the conservation of energy and balance the centripetal and centrifugal forces.
The more massive is an object and the smaller is its radius the greater or smaller is the escape velocity from it?
For two bodies with equal radius, the more massive has the greater escape velocity. For two bodies with equal mass, the one with smaller radius has the greater escape velocity. Both conditions listed in the question indicate greaterescape velocity.
What two quantities does rotational inertia depend?
mass, velocity and radius
When does centripetal force double?
Since a=Rω², when you double the radius, but hold the angular velocity constant, you double the force. Also when you increase the angular velocity or velocity by a factor of √2 and hold the radius constant.

Question Modified: this is the complete question.
A gear radius 0.4m and a gear radius 1.2m are connected by a belt If the smaller gear is rotating with an angular velocity of 10rads what is the angular velocity of the larger gear?
10/3
What is the relationship between centripetal force and velocity?
Centripetal force is = mass * velocity square divided by radius
