C, electrons are negative, and most of the atom’s mass comes from the nucleus of the atom
For the answer to the question above, on Earth, a one-pound object has a mass of about 0.453592 kilograms.
<span>Therefore the man's mass is 155 * 0.453592 = 70.30676 kilograms. </span>
<span>The part about the Moon's gravity is irrelevant. While the weight of a person or object would be different on the Moon, the mass would be the same.</span>
Convex lenses are thicker at the centers than the edges, they are known as the converging lenses. Rays of light that pass through the lens are brought closer together (they converge). When rays of light that are parallel pass through a convex lens they are refracted, the refracted rays converge at one point called the principal focus.
Answer:
Negative 9.8 meters per second squared
Explanation:
The negative is for the direction (down, towards the center of the earth). Often this can be estimated as -10 m/s^2 to make calculations easier.
