How did elements with more than 2 protons, such as the carbon in our cells, form? a. they formed 400 million years after the universe formed in giant fusion reactors known as stars.
b. they formed from hydrogen and helium slamming into each other in the first few minutes after the big bang.
c. they are formed when lighter elements are pulled together by gravity to form a planet.
d. they were formed at the same time as hydrogen and helium right after the big bang.

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called

If the textbook weighs 19.6 newtons on venus, what is the strength of gravity on venus?

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
