An electrical motor spins at a constant 2695.0 rpm. if the armature radius is 7.165 cm, what is the acceleration of the edge of the rotor?
a) 28.20 m/s^2

b) 572,400 m/s^2

c) 281.6 m/s^2

d) 5707 m/s^2

Acceleration will be

So option (D) will be correct answer

Explanation:

We have given angular speed of the electrical motor

We have to change this angular speed in rad/sec for further calculation

So

Armature radius is given r = 7.165 cm = 0.07165 m

We have to find the acceleration of edge of motor

Acceleration is given by

So acceleration will be

So option (D) will be correct answer

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
