Answer:
The answer is OA it will increase.
Explanation:
Which of the following is part of the internal energy of a substance?
O A. Kinetic energy from nuclear forces
B. Kinetic energy from intermolecular forces
O C. Potential energy from nuclear forces
O D. Potential energy from intermolecular forces
The correct answer is Potential energy from intermolecular forces.
Potential energy from intermolecular forces is part of the internal energy of a substance, therefore the correct option is D.
What is internal energy?It is the total energy of the substance that is contained in the system which is the sum of all the kinetic energy and potential energy of the molecules and the atoms contained in it.
The potential energy of the intermolecular forces is also part of the internal energy of the substance.

3. There are twice as many people in the household, but your income has also doubled. Is your new
tax liability about twice as much as when you were single, more than twice as much, or less than
twice as much? Tell whether you think this difference-or the lack of one-seems fair.
Answer:
The answer is less than twice as much.
Explanation:
When the income doubles, the personal tax liability also doubles. However, because I have more dependents on my household, I'm able to get tax reductions to take care of the dependents.

a wave carries___ from one place to another.
mechanical waves carry energy through___.
Energy
A material medium
A wave carries energy from one place to another. Mechanical waves carry energy through a material medium.
What is a wave?A wave is a phenomenon that flows across a material medium without leaving any lasting mark.
Mechanical or electromagnetic waves can be used to classify them. Transverse and longitudinal are the two main forms.
A wave carries energy from one place to another. Mechanical waves carry energy through a material medium.

nRT
A. 1540 m/s
B. 876 m/s
C. 87.6 m/s
O D. 15,400 m/s
Answer:
v = 876 m/s
Explanation:
It is given that,
Number of mol of Neon is 2 mol
Temperature, T = 308 K
Mass, m = 0.02 kg
Value of R - 8.31 J/mol-K
We need to find the average velocity of atoms in 2.00 mol of neon. Neon is a monoatomic gas. Let v is the velocity. So,
[tex]\dfrac{1}{2}mv^2=\dfrac{3}{2}nRT\\\\v=\sqrt{\dfrac{3nRT}{m}} \\\\v=\sqrt{\dfrac{3\times 2\times 8.314\times 308}{0.02}} \\\\v=876.47\ m/s[/tex]
So, the correct option is (B).
What did Thomson’s and Rutherford’s experiments have in common? They both used charged particles in their experiments. They both used emission spectra to discover electron clouds. They both compared the atom to an indivisible sphere. They both discovered electron clouds.
