Answer:
metre per seconds
Explanation:
because velocity = distance ÷ time
To finish one orbit it will take 98 x 60 seconds. So; <span>(2 x pi)/(98 x 60) = 1.07 x 10^-3 rad/sec. </span><span>

Answer:
The excess charge has distributed itself evenly over the outside surface of the sphere.
Explanation:
Since the hollow sphere is a conductor, it has free electrons that can move about within the sphere. In this light, an excess charge, the like charges repels each other, therefore ensuring that charges are spread as far apart as possible. There is therefore an evenly distributed charge on the outside surface of the sphere.
Sublimation is the transition of a substance directly from the solid state to the gas state; therefore:
c. solid to a gas
