Answer:
Explanation:
Because when the electric bulb at night switched It emitted the light this light rays forms an image on our retina hence the bulb become visible at night
2 ans
When an electric bulb is switched on, the electricity is allowed to pass in its circuit and is converted into light energy. Thus, a bulb glows when switched on and the eyes perceives the light energy in the visible spectra which is given out by the bulb. Hence, the bulb becomes visible
-- Earth's average distance from the sun is about 93 million miles.
-- Mars' average distance around the sun is about 142 million miles.
-- So, as both planets travel in their orbits around the sun, the distance
between them changes, between (142 - 93) = about 49 million miles
and (142 + 93) = about 235 million miles.
Neither the speed nor the distance of a falling object is linearly related to time.
