A rock is thrown with a force of 500 N and an acceleration is 75 m/s^2. What is its mass? A. 575 kg
B. 3.8 x 104 kg
C. 0.15 kg
D. 6.7 kg

We conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.

Hence, option D is correct.

Explanation:

Given

To determine

Mass m = ?

Important Tip:

Using the formula

where

now substituting F = 500, and a = 75 m/s² in the formula

switch sides

Divide both sides by 75

simplify

kg

Therefore, we conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.

Hence, option D is correct.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
