A solid disk of mass 9.2kg and radius 0.55 m is rotating clockwise about it’s axis of rotating at 19 radians per second. A cylindrical hoop of mass 5.1Kg with radius .035m is rotating counterclockwise and its axis of rotation at 21 radius per second . The two axis are the same, and the cylinder hoop is dropped so that it is centered on the rotating disk. Determine the angular velocity of the system on the hoop and disk toghter

Explanation: they are the same  mass per second

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
