. a positive charge always moves from a higher potential to a lower potential is right answer.
Explanation:
Newton's 1st law: An object in motion stays in motion, and an object at rest stays at rest, until acted upon by an unbalanced force.
Newton's 2nd law: Force equals mass times acceleration.
Newton's 3rd law: For every action, there is an opposite and equal reaction.
Radiation is the flow of energy by means of electromagnetic waves.
Answer:
<u>real and upside down </u>
Explanation:
Lens of a camera gathers light and focuses it on the light detector or film strip. <u>A real and inverted (upside -down) image is formed. </u>This image is then stored and processed and inverted. Thereafter we see an upright image. A chemical reaction on the film strip stores the image. In a digital lens, a light detector such as CCD stores the image.
All electromagnetic waves travel at the same speed in a vacuum: 3.0 x 10^5 (300,000) kilometres per second. some electromagnetic waves are part of the visible light spectrum and some do emit harmful radiation, but certainly not all. they travel fine on earth without the vacuum of space too.
