The highest entropy for the jar of marbles is represented by the marbles are arranged in a random order.

<h3>What is entropy?</h3>

Entropy is the measure of the degree of disorderliness of a system or degree of randomness of a system.

Entropy of a system increases with increase in randomness of the system or disorderliness of the system.

Thus, the highest entropy for the jar of marbles is represented by the marbles are arranged in a random order.

3. Two spherical objects at the same altitude move with identical velocities and experience the same drag force at a time t. If
Daniel [21]

Answer:

Object 2 has the larger drag coefficient

Explanation:

The drag force, D, is given by the equation:

D = 0.5 c \rho A v^2

Object 1 has twice the diameter of object 2.

If d_2 = d

d_1 = 2d

Area of object 2, A_2 = \frac{\pi d^2 }{4}

Area of object 1:

A_1 = \frac{\pi (2d)^2 }{4}\\A_1 = \pi d^2

Since all other parameters are still the same except the drag coefficient:

For object 1:

D = 0.5 c_1 \rho A_1 v^2\\D = 0.5 c_1 \rho (\pi d^2) v^2

For object 2:

D = 0.5 c_2 \rho A_2 v^2\\D = 0.5 c_2 \rho (\pi d^2/4) v^2

Since the drag force for the two objects are the same:

0.5 c_1 \rho (\pi d^2) v^2 = 0.5 c_2 \rho (\pi d^2/4) v^2\\4c_1 = c_2

Obviously from the equation above, c₂ is larger than c₁, this means that object 2 has the larger drag coefficient

The correct answer is:
<span>C: in the protons and neutrons of an atom

In fact, the nuclear energy refers to the binding energy of the nucleons (protons and neutrons) of an atom. The protons and the neutrons are held together by the strong nuclear interaction, one of the four fundamental forces of nature, and the energy associated to this interaction is called nuclear energy.
