A Ferris wheel cart has a mass of 800 kg as it spins around a radius of 32 m. If the Ferris wheel travels with a tangential velocity of 1.2 m/s, what is the centripetal force on the Ferris wheel?

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

What are similarities and differences between refraction, reflection, diffraction and absorption?
