why is the freezer compartment of a refrigerator kept at the top in terms of conduction convection and radiation​

Answer: c. some of the energy in their mass is released

Explanation:

While heavier atoms like uranium, thorium, and plutonium are more fissionable, nuclear fusion uses lighter elements like hydrogen and helium, which are often more fusible. Thus, option C is correct.

A heavier nucleus is created when two light nuclei fuse together in a fusion reaction. Because the mass of the resulting single nucleus is smaller than the combined mass of the two initial nuclei, the process produces energy. Remaining mass is converted to energy.

Proton-proton fusion is the particular kind of fusion that takes place inside the Sun. Protons, which are just solitary hydrogen nuclei, are the starting point of this process inside the Sun.

Therefore, After a series of processes, these protons fuse together to form helium.

Answer:

The temperature would be 95F .

Explanation:

At 95⁰F temperature, water has particles with a greater average kinetic energy than water with a temperature of 30°C.

Kinetic energy is a form of energy that an object possesses by virtue of its motion. It is defined as the energy that an object possesses due to its motion and is proportional to the mass of the object and the square of its velocity.

The formula for kinetic energy is:

KE = (1/2)mv²

Where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.

Here in the question,

The kinetic energy of the particles in water increases with temperature. So, we need to find the temperature at which water has particles with a greater average kinetic energy than water at 30°C.

To compare the kinetic energy of water at different temperatures, we can use the formula:

KE = (1/2)mv^2

Where KE is the kinetic energy of the particles, m is the mass of a particle, and v is the velocity of a particle.

The average kinetic energy of the particles in water is proportional to the temperature in Kelvin, according to the formula:

KE = (3/2)kT

Where k is the Boltzmann constant and T is the temperature in Kelvin.

Using this formula, we can find the temperature at which water has particles with a greater average kinetic energy than water at 30°C:

KE1 = (3/2)k(30 + 273.15) = 4.14 x 10^-21 J

To find the temperature at which water has a greater kinetic energy, we need to find the temperature that corresponds to a kinetic energy greater than 4.14 x 10^-21 J.

Option A: 77°F = 25°C = 298.15K

KE2 = (3/2)k(298.15) = 5.06 x 10^-21 J

Option B: 95°F = 35°C = 308.15K

KE3 = (3/2)k(308.15) = 5.55 x 10^-21 J

Option C: 280K

KE4 = (3/2)k(280) = 4.85 x 10^-21 J

Option D: 300K

KE5 = (3/2)k(300) = 5.24 x 10^-21 J

Therefore, the temperature at which water has particles with a greater average kinetic energy than water at 30°C is Option B: 95°F (35°C or 308.15K).

The electric potential of the 4.5 × 10^(-5) C charge with an electric potential energy of 0.027 J is 600 J/C.

To find the electric potential (V) of a charge given its electric potential energy (U), you can use the formula:

V = U / q

where V is the electric potential, U is the electric potential energy, and q is the charge.

Plugging in the values you provided:

U = 0.027 J

q = 4.5 × 10^(-5) C

Using the formula, we can calculate the electric potential:

V = U / q

V = 0.027 J / (4.5 × 10^(-5) C)

To simplify the calculation, let's express the charge in scientific notation:

V = 0.027 J / (4.5 × 10^(-5) C)

V = 0.027 J / (0.000045 C)

Now divide 0.027 J by 0.000045 C to find the electric potential:

V ≈ 600 J/C

Therefore, the electric potential of the 4.5 × 10^(-5) C charge with an electric potential energy of 0.027 J is approximately 600 J/C.

The final speed of puck A is 1.8 m/s and the final speed of puck B is 3.7 m/s.

The final speed of the pucks is determined by applying the principle of conservation of linear momentum.

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

0.025(5.5) + 0.05(0) = 0.025v₁ + 0.05v₂

0.1375 = 0.025v₁ + 0.05v₂

u₁ + v₁ = u₂ + v₂

5.5 + v₁ = 0 + v₂

v₁ = v₂ - 5.5

0.1375 = 0.025(v₂ - 5.5) + 0.05v₂

0.1375 = 0.025v₂ - 0.1375 + 0.05v₂

0.275 = 0.075v₂

v₂ = 0.275/0.075

v₂ = 3.7 m/s

v₁ = 3.7 - 5.5

v₁ = -1.8 m/s

Thus, the final speed of puck A is 1.8 m/s and the final speed of puck B is 3.7 m/s.

Answer:

The question is somewhat vague in that acceleration is not exactly defined:

Usually a = (v2 - v1) / t    which would imply that

a = 32 / g = 32 / 9.8 = 3.27   the acceleration due to change in speed of the rocket

One can also say that the astronaut experiences an acceleration of 9.8 m/s^2 just by being motionless on the surface of the earth.

Then a = (32 - 9.8) / 9.8 = 2.27 due to the acceleration of the rocket

If we assume the first condition then

F = 65 kg * 3.27 * 9.8 m/s^2 = 2083 N
