What is the definition of density

A uniform sphere with a mass of 23.0 kg and a radius of 0.330 m rotates at a constant angular velocity around a stationary axis that coincides with the sphere's diameter. Part A: If the sphere's kinetic energy is 238 J, what is the tangential velocity of a point on the sphere's rim?

Under new homeland security measures boats must keep at least how many hours away from all military vessels and ships ?

How do Newton's laws of motion explain the importance of maintaining a smooth surface on a hockey rink to enable players to pass the puck quickly? Smooth ice reduces friction, allowing the puck to maintain its motion with less force. It minimizes resistance, meaning less force is required to accelerate the puck. Smooth ice also reduces the disruptive forces that could decelerate the puck. Lastly, a sleek surface decreases the reaction force exerted by the ice on the puck, facilitating faster movement.

A region of space contains a uniform electric field oriented along the y-axis. A frame of surface area A is placed perpendicular to the y-axis in the xz-plane. The magnitude of the electric flux through this frame is Φ0. A second frame is placed in the same electric field in such a way that the magnitude of the electric flux through it is Φ0/2. How is the plane of second frame oriented with respect to the plane of the first one?

A gargoyle statue falls off the side of a building from a height of 75 m. (Assume no air resistance.) How fast is the statue moving when it reaches the ground?​

If an ant starts at 0 radians and travels to 4.5 radians in 18 seconds, what is its angular velocity? If the ant then slows to 0 rad/s in 3 seconds, what is its angular acceleration?

If the current flowing through a circuit of constant resistance is doubled, the power dissipated by that circuit will Group of answer choices
