C. protons dont circle the nucleus of an atom
Well, the equation describes the relationship among
three physical quantities ...
E . . . energy
m . . . mass
c . . . the speed of light.
Speaking strictly algebraically, if you know any two of them,
you can use the equation to calculate the third one.
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.

Answer:
U=1.44 J
Explanation:
Given that
m = 3.7 kg
K = 450 N/m
X= 0.08 m
We know that spring stored potential energy(U) and this potential energy given as
By putting the values
U=1.44 J
Answer:
14700 J
Explanation:
The gravitational potential energy of an object is given by:
where
m is the mass
g is the gravitational acceleration
h is the height of the object above the ground
In this problem:
m = 50 kg is the mass of the hiker
h = 30 m is the heigth of the cliff
Substituting, we find
