Two solid cylinders are rotating about an axis that passes through the center of both ends of each cylinder. cylinder a has half the mass and twice the radius of cylinder b, but they have the same rotational kinetic energy. what is the ratio of the angular velocities, ns/on, for these two cylinders? take the moment of inertia for a solid cylinder as mr? , with mass m and radius r.- a) 0.28 b) 0.71 c) 0.50 d) 1.0 e) 4.0

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
