Answer:
Explanation:
I can tell you what the answers for the middle column are, but if you don't know how to solve total energy problems, they won't make any sense to you at all.
First row, KE = 0
Second row, KE = 220500 J
Third row, KE = 183750 J
Fourth row, KE = 205800 J
That's also not paying any attention to significant digits because your velocity only had 1 and that's not enough to do the problem justice. I left all the digits in the answer. Round how your teacher tells you to.
Answer:
Equilibrium. • When an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero.
True
Explanation:
Nuclear reactions have many useful applications but they also have harmful biological effects. Nuclear reactions are that occurs in the nucleus of an atoms. They differ from chemical reactions which occurs using valence electrons.
Some uses of nuclear reactions:
- They are used for cancer therapy
- Radioactive tracers.
- Production of energy
- Radiometric dating
Some harmful effects:
- Uncontrolled nuclear reactions can lead to nuclear wastes in the environment.
- They are used in manufacturing nuclear weapons.
- They cause destruction of living cells because they produce ionizing radiations.
