Answer:
The completed equations are as follows: 2713Al+42He⟶3015P+10n 13 27 Al + 2 4 He ⟶ 15 30 P + 0 1 n; 23994Pu+42He⟶24296Cm+10n 94 239 Pu + 2 4 He ⟶ 96 242 Cm + 0 1 n; 147N+42He⟶178O+11H 7 14 N
1). The forces inside the atom are always, totally, completely, electrostatic forces. Those are so awesomely stronger than the gravitational forces that the gravitational ones are totally ignored, and it doesn't change a thing.
Parts 2 and 3 of this question are here to show us how the forces compare.
Part-2). The electrostatic force between a proton and an electron.
The constant in the formula is 9x10^9, and the elementary charge is 1.602 x 10^-19 Coulomb ... same charge on both particles, but opposite signs.
I worked through it 3 times and got 0.000105 N every time. So the best choice is 'C', even though we disagree by a factor of ten times. You'll see in part-3 that it really doesn't make any difference.
Part-3). Gravitational force between a proton and an electron.
The constant in Newton's gravity formula is 6.67x10^-11 . You'll have to look up the masses of the proton and the electron.
I got 2.163 x 10^-55 N ... exactly choice-C. yay !
Now, after we've slaved over a hot calculator all night, the thing that really amazes us is not only that the electrostatic force is stronger than the gravitational force, but HOW MUCH stronger ... 10^51 TIMES stronger. That's a thousand trillion trillion trillion trillion times stronger !
That's why it has no effect on the measurements if we just forget all about the gravitational forces inside the atom.
Because the car has more mass than the wheel spinning backwards
Real gases are those, which deviate from ideal behavior.
Answer: Option D
<u>Explanation:
</u>
Very tiny particles are present in real gases and occupying finite space by exerting some specific interactions between them. It takes as the reason for why it deviates from its behaviour. There is a lot of difference between a real gas and ideal gas. Ideal gas is the one that which is imaginary, and does not exist. Its characteristics are ideal, and all other real gases, try to follow them.
Real gases, are available in the atmosphere, but need not be naturally available. There is no relation between number of protons and nature. And, they won’t behave ideally, at any conditions. We calculate the characteristics of a real gas using ideal gas equation, only because it is very difficult to determine their behaviour.
In a mixture, there will be a solute and solvent. The hydrogen and oxygen are still two different atoms that just mixed together. But in a compound, the hydrogen and oxygen have a bond, making a new and bigger molecule. A mixture can easily be separated by physical means but a compound isn't.
