The energy released per kilogram of fuel used is 3.39 * 1014 J/Kg

Energy is released in a reaction because of  the breaking of bonds are well as formation of bonds.

The quantity of energy released in reactions differs according to the reaction type involved.

The energy released in nuclear reactions are far larger than that released in chemical reactions due to the release of nuclear energy from the nucleus.

The energy, E released in nuclear reactions is given by the formula below:

Energy per kilogram of reactants (in joules) = Energy per mole of reactants (in joules) / Total molar mass of reactants (in kg)

Energy per kilogram of reactants (in joules)  = [tex]1.60218 x 10^-^1^3 joules[/tex] /  5 grams

Energy per kilogram of reactants (in joules)   =  3.39 * 1014 J/Kg

The energy released per kilogram of fuel used is 5.632 × 10^-14 J/kg.

5 grammes, 0.005 kilogrammes, of reactants are provided.

Since 1 mile of tritium and 1 mile of deuterium are equal to 1 mole of "reactions," the sum of the "reactions" in 0.005 kilogrammes of reactants may be computed as follows:

Total moles of "reactions" in 0.005 kg of reactants = (0.005 kg / 5 g/mol)                            

                                                                                     = 0.001 mole.

The MeV per reaction must now be multiplied by the total number of "reactions" in order to get the total energy released by the "reactions."

Next, the energy must be converted from MeV to Joules.

MeV to Joules conversion factor is 1.6 10-13 J/MeV.

Total energy released = (MeV per reaction) x (number of reactions) x (conversion factor)

Total energy released = (17.6 MeV/reaction) x (0.001 mole) x (1.6 × 10^-13 J/MeV)

Total energy released = 2.816 × 10^-16 J

The total energy released by the "reactions" is 2.816 × 10^-16 J.

To determine the energy released per kilogram of fuel used, we need to divide the total energy by the mass of fuel used.

Total energy released per kilogram of fuel used = (total energy released) / (mass of fuel used)

Total energy released per kilogram of fuel used = (2.816 × 10^-16 J) / (0.005 kg)

Total energy released per kilogram of fuel used = 5.632 × 10^-14 J/kg

Therefore, the energy released per kilogram of fuel used is 5.632 × 10^-14 J/kg.

The work done on the block by the applied force is approximately -23.04 Joules.

The negative sign indicates that the work done is in the opposite direction of the displacement, as the force is directed below the horizontal.

In this scenario, the block of mass 2.50 kg is being pushed along a frictionless horizontal table by a constant applied force of magnitude 18.0 N, directed at an angle of 25.0° below the horizontal.

To determine the work done on the block by the applied force, we can use the formula:

Work = Force * Distance * cos(theta)

where the force is 18.0 N, the distance is 2.30 m, and theta is the angle between the force and the direction of displacement.

Since the force is directed at an angle below the horizontal, the angle theta is 180° - 25° = 155°, as the angle is measured with respect to the horizontal axis.

Now we can calculate the work done:

Work = 18.0 N * 2.30 m * cos(155°)

The cosine of 155° is negative, as it is in the third quadrant.

Work = 18.0 N * 2.30 m * (-0.57358)

Work ≈ -23.04 J

Therefore, the work done on the block by the applied force is approximately -23.04 Joules.

The negative sign indicates that the work done is in the opposite direction of the displacement, as the force is directed below the horizontal.

If the parallel circuit had 23 amps with the same resistance, the voltage will be V = 23 amps * R.

To determine the voltage in a parallel circuit with a given current and resistance, we can use Ohm's Law, which states that the voltage (V) is equal to the current (I) multiplied by the resistance (R).

In this case, if the parallel circuit has a current of 23 amps and the same resistance as before, we can use the same resistance value as before to calculate the voltage.

Ohm's Law equation: V = I * R

Given:

Current, I = 23 amps

Resistance, R (same as before)

Substituting the values into the equation, we have:

V = 23 amps * R

Therefore, The specific value of resistance (R) is not provided in the question, so the voltage (V) cannot be determined without knowing the resistance value. If the resistance value is provided, you can substitute it into the equation to calculate the voltage.

Explanation:

Falt isn't a size. I guess you were trying to spell flat. No, the earth isn't flat. instead, it is round.

Answer:

Earth is round. But the map shows you flat.

The acceleration of the car is approximately -3.06 m/s^2.

To find the acceleration of the car, we can use the kinematic equation:

v^2 = u^2 + 2as

Where:

v = final velocity = 0 m/s

u = initial velocity = 14 m/s

a = acceleration (to be determined)

s = displacement = 32 m

Plugging in the values into the equation, we can solve for acceleration:

0^2 = 14^2 + 2a(32)

Simplifying:

0 = 196 + 64a

Rearranging the equation:

64a = -196

Dividing both sides by 64:

a = -196/64

a ≈ -3.06 m/s^2

This means that every second, the car's velocity decreases by 3.06 meters per second. The negative sign indicates that the acceleration is in the opposite direction of the initial velocity, opposing the car's motion and bringing it to a stop.

Pressure builds under the surface of Earth, causing mountains to form.The correct answer is option D.

Uplift refers to the geological process that elevates the Earth's surface, resulting in the formation of mountains. This process is primarily driven by tectonic forces, including the movement and collision of Earth's lithospheric plates.

When two plates converge, immense pressure builds up beneath the surface, causing the crust to buckle and fold. This deformation leads to the formation of mountains, as rocks are pushed upward and displaced vertically.

As the uplift process continues over millions of years, mountains gradually take shape. Erosion and weathering play significant roles in shaping their features, but it is the initial uplift that initiates the formation of mountains.

As the Earth's surface is elevated, a wide range of landforms can emerge, including rugged peaks, deep valleys, and steep slopes.

Uplift has a profound impact on the Earth's surface and ecosystems. Mountains alter local climates, influencing precipitation patterns and creating variations in temperature and wind patterns.

Therefore, uplift plays a crucial role in shaping the Earth's surface and influencing various geological, biological, and climatic processes.
