C. When the center of Earth is 2 x 10 meters from the center of Mars, the force of gravity between the two planets is about 64.32 * 1014 newtons. The mass of Earth is about
6 x 1024 kilograms, and the mass of Mars is about 6.4 * 1023 kilograms. Using these
values, estimate the gravitational constant.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168

it is 28 degrees colder in detroit than philadelphia.

step-by-step explanation:

what number adds to 21

-7 + ? = 21

-7 + 28 = 21

hope it
