The advantages  of using nuclear energy are: carbon-free, Small land footprint, High power output, Reliable energy source but the disadvantages of using nuclear energy are Very high upfront costs, Nuclear waste, Malfunctions can be catastrophic.

The energy source located in the nucleus, or core, of an atom is known as nuclear energy. Once captured, this energy can be used to generate electricity by causing nuclear fission in a reactor by either nuclear fusion or nuclear fission, two different types of atomic reactions.

The latter causes atoms to divide into two or more nuclei when uranium is utilised as fuel. The heat produced by the fission energy causes a cooling agent, typically water, to boil. The steam produced by boiling or pressurized water is then sent into turbines, which spin and produce power. Uranium is the fuel used in reactors to create nuclear fission.

Nuclear energy is the form of energy released from the nucleus, the core of atoms released from protons and neutrons. Nuclear energy is produced by two types and they are nuclear fission and fusion.

Nuclear fusion is the process of fusing two lighter nuclei and nuclear fission is the splitting of heavier nuclei into two lighter nuclei and releasing energy is called nuclear energy.

The advantage of nuclear energy is it produces more amount energy from less fuel and produces low pollution. No emission of greenhouse from nuclear energy.

The disadvantage of nuclear energy is, that radioactive waste is the result of nuclear power plants which is a big threat to the environment. It is a not form of renewable energy. It involves huge investment and is not economical.

Answer:

[tex]\boxed {\boxed {\sf 10,000 \ Newtons}}[/tex]

Explanation:

We are asked to find the force of Annabella's car when it hits a tree.

According to Newton's Second Law of Motion, force is the product of mass and acceleration.  Therefore, it is calculated using the following formula:

[tex]F=ma[/tex]

The mass of the car is 5000 kilograms and the acceleration is 2 meters per second squared.

Substitute the values into the formula.

[tex]F= (5000 \ kg)(2 \ m/s^2)[/tex]

Multiply.

[tex]F= 10,000 \ kg*m/s^2[/tex]

Convert the units. 1 kilogram meter per second squared is equal to 1 Newton, so our answer of 10,000 kg*m/s² is equal to 10,000 Newtons.

[tex]F= 10,000 \ N[/tex]

Annabella's car hits the tree with a force of 10,000 Newtons.

The book's initial speed = 2.83 m/s

The mass of the textbook, m = 0.75 kg

The final speed of the textbook, v = 0 m/s (Since it comes to rest)

The distance covered by the book, d = 1.2 m

Coefficient of kinetic friction, [tex]\mu = 0.34[/tex]

The frictional force between the table and the book is calculated as:

The given parameters:

The total voltage in a series circuit is given as;

[tex]V_T = IR_1 + IR_2\\\\V_T = V_1 + V_2[/tex]

The voltage drop in the second resistor is calculated as follows;

Answer:

Explanation:

Kinetic energy of a body is given by the formula [tex]K= {1\over2} m v^2[/tex]. Let's replace everything we have and solve for what's left.

[tex]1125J = {1\over2}\cdot 250 kg \cdot v^2[/tex]

[tex]v^2 ={ 1125 \cdot 2 \over 250}}[/tex] or [tex]v= 3 {m \over s}[/tex]

A. 95 Cal is equivalent to 397480 J

B. The final speed of the object is 625.78 m/s

C. The final temperature of the water is 46.8 °C

A. Converting 95 Cal to Joules

1 Cal = 4184 J

Therefore,

95 Cal = 95 × 4184

Thus, 95 Cal is equivalent to 397480 J

B. Determination of the speed of the object

Kinetic energy (KE) = 397480 J

Mass (m) = 2.03 Kg

KE = ½mv²

397480 = ½ × 2.03 × v²

397480 = 1.015 × v²

Divide both side by 1.015

v² = 397480 / 1.015

Take the square root of both side

v = √(397480 / 1.015)

Therefore, the speed of the object is 625.78 m/s

C. Determination of the final temperature of the water

Mass of water (M) = 3.79 kg

Initial temperature of water (T₁) = 21.7 °C

Specific heat capacity of water (C) = 4186 J/KgºC

Heat (Q) = 397480 J

Q = MC(T₂ – T₁)

397480 = 3.79 × 4186 (T₂ – 21.7)

397480 = 15864.94 (T₂ – 21.7)

Clear the bracket

397480 = 15864.94T₂ – 344269.198

Collect like terms

397480 + 344269.198 = 15864.94T₂

741749.198 = 15864.94T₂

Divide both side by 15864.94

T₂ = 741749.198 / 15864.94

Therefore, the final temperature of the water is 46.8 °C
