Mike enters a revolving door that is not moving. Mike should
push at the edge of the door where it is largest distance from the pivot point
in order to produce a torque with the least amount of force. Torque is equal to
t = force x distance.
The moon and the Earth attract each other, with equal gravitational forces.
That may not sound too surprising.
But what do you think of THIS one:
-- You and the Earth attract each other, with equal gravitational forces.
-- Your weight on Earth is the same as the Earth's weight on you.
Answer:
D) Electric power distribution.
Explanation:
Electric power distribution requires high voltages to efficiently transmit electric power. This requires use of a transformer which uses electromagnetic induction.
Answer:
This is because these metals are used for minting (making) coins.
Kinetic energy= 1/2 m v^2
so... 1/2(1350)(12^2)
kinetic energy = 97200Joules
