Everyone's favorite flying sport disk can be approximated as the combination of a thin outer hoop and a uniform disk, both of diameter Dd=0.273 m. The mass of the hoop part is mh=0.120 kg and the mass of the disk part is md=0.050 kg. You would like to make a boomerang that has the same total moment of inertia, around its center, as the sport disk. The boomerang is to be constructed in the shape of an \"X,\" which can be approximated as two thin uniform rods joined at their midpoints. If the total mass of the boomerang is to be mb = 0.245 kg, what must be the length Lb of the boomerang?

The length of the boomerang is 0.364 m

Explanation:

The moment of inertia is:

Where

md = 0.05 kg

mh = 0.12 kg

r = d/2 = 0.273/2 = 0.1365 m

The length of the boomerang is:

the largest known star in the universe is uy scuti, a hypergiant with a radius around 1,700 times larger than the

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
