Answer:
24
Explanation:
24.305 of atomic mass has 12 neutrons
Answer:
Explanation:
The equation for centripetal force is
. We have all the values we need except for the radius. We have the circumference of the circle, though, so we will solve for the radius using that and the fact that C = 2πr:
3.04 = 2(3.1415)r and
r = .484 m, to the correct number of sig fig's.
Now that we have everything we need and isolating the v NOT squared:
and filling in:
. This answer will need 2 sig fig's since 2100 has 2 sig fig's in it. That means that the velocity of the test car is
1.1 m/sec
True because the speed of a mass can change it's gravitational potential energy in the gravitational field of another massive object.
Energy is always needed to preform anything, and chemical energy is one form of energy. Chemical energy is a part of chemical reactions because it involves teh chemicals.
