Thank you for posting your question here and Brainly!~
Even though you have not provided answer choices, I believe the answer is whatever letter corresponds with the answer: "It is rubbed with another object, and electrons move onto the rod."
Hope I helped!~ Brainliest appreciated.
The speed of light is determined by the medium (material) through which the light is travelling. Light travels faster in a vacuum than it does in any other medium. Light changes speed as it passes from one medium to another. This is called refraction.
Explanation:
Distance travelled (d) = 56 metres
Time taken (t) = 7 seconds
velocity of the object (V)
= d / t
= 56 / 7
= 8 m/s
The velocity of the object is 8 m/s.
Hope it will help :)
