Answer:
Explanation:
True
It is correct as the total rotational energy is the sum of transnational kinetic energy of each small piece of the object.
Consider a rigid body made of small particles each of mass dm have same angular velocity ω and the radius of the rotational path is r.
The velocity of each particle is v = r ω
So, the kinetic energy of each particle is
dK = 0.5 dm x v² = 0.5 x dm x r² x ω²
The total kinetic energy
K = 0.5 x I ω²
where, I is the moment of inertia
What a sloppy question ! The purpose of a fuse or circuit breaker is to shut down the circuit when current reaches a magnitude indicating danger due to a serious malfunction. When current IS flowing in the circuit, it's always flowing at the same speed.

The pressure between two costs is proportional to the product of the charges.
If solely one of the expenses is decreased by way of a element of 3, then the pressure is decreased with the aid of a thing of 3.
If each prices are reduced by a thing of 3, then the pressure is reduced via a issue of 9.

Answer:
Explanation:
speed of sound in 24 degrees celsius
345.48m/s
hence 345.48m/s x 3s = 1036.44m
