Answer:
v = 12.12 m/s
Explanation:
It is given that,
Radius of circle, r = 30 m
The coefficient friction between tires and road is 0.5,
The centripetal force is balanced by the force of friction such that,
v = 12.12 m/s
So, the maximum speed with which this car can round this curve is 12.12 m/s. Hence, this is the required solution.
The state of matter would have to be solid
Answer: True
Explanation: Inductors are similar to resistors, due to the fact that they offer resistance to current flow, but Inductors are different from resistors in that, while resistors loss electric energy in a circuit in the form of heat, an inductor stores that energy in the form of a magnetic field.
As current passes through an inductor overtime it tends to store current in the form of magnetic field. Therefore the electric-power industry can store energy in large Inductors.
I believe it is False, only because the plane is Frictionless. Hope this helps, good luck.
Answer: 1 / 4.283 x 10¹¹
the earth model will be 64 cm away from the tennis ball
Explanation:
0.03 / 7 x 10⁸ = 1 / 4.283 x 10¹¹
(1.5 x 10¹⁰)( 1 / 4.283 x 10¹¹) = 0.64285
