Uranium 238, a common isotope of natural uranium (u), decays to form an isotope of thorium (th) which has an atomic mass of 234 amu and 90 protons. how many fewer protons are found in each nucleus of thorium 234 than are found in each nucleus of uranium 238?

2 protons.

Explanation:

1) The number of protons is indicated by the atomic number (Z)

2) Atomic number of uranium-238 and any uranium isotope is the same: 92. You find it in a periodic table.

So, the number of protons of uranium-238 is 92.

3) Atomic number of thorium-234 (and any thorium isotope) is 90, that is why it is told that it has 90 protons.

4) Therefore, the difference on the number of protons in each nucleus of uranium-238 and thorium-234 is 92 - 90 = 2.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
