A solid sphere of radius R, a solid cylinder of radius R, and a rod of length R all have the same mass, and all three are rotati

ng with the same angular velocity. The sphere is rotating around an axis through its center. The cylinder is rotating around its long axis, and the rod is rotating around an axis through its center but perpendicular to the rod. 1) Which one has the greatest rotational kinetic energy

Answer:

I(sphere) = 2/5 M R^2

I(rod) = 1/3 M L^2

I(cylinder) = 1/2 M R^2

From the information given I would assume that

the cylinder is the correct answer.

A current of 2 A flows through a resistor. The voltage across the resistor is 18 V.
stepan [7]

Answer:

R=9\ \Omega

Explanation:

Given that,

Current, I = 2 A

Voltage across the resistor, V = 18 V

We need to find the value of resistance of the resistor. Let the resistance be R. We can find it using Ohm's law i.e.

V = IR

Where

R is the resistance of the resistor

R=\dfrac{V}{I}\\\\R=\dfrac{18}{2}\\\\R=9\ \Omega

So, the resistance of the resistor is equal to 9\ \Omega.

Aluminum allows for the flow of electrons, while glass does not. Would an aluminum wire surrounded by glass be an effective desi
pantera1 [17]

answer

no

Explanation:

I do not think that I would because even though its a conductor in the insulator I think it would insulate it before it will work (not sure if that makes sense)
