An acrobat with a mass of 49-kg jumping on a trampoline, the force that the trampoline has to apply to accelerate her straight up at \(7.9m/s^2\) in newtons is 867.3 N.

How to calculate force? Force is the product of mass and acceleration.

Hence, F = ma

Where, F = Net force applied

            m = mass of an object

            a = net acceleration

Force can be calculated by multiplying the mass of the object with the acceleration experienced by it.

In this case, m = 49kg and a = \(7.9 m/s^2\)

Force applied by earth gravity on the acrobat is mg, which equals 49*9.8 N i.e., 480.2 N.

\(F - F_{gravity}=ma \\F-F_{gravity} = ma\\F = F_{gravity}+ma\\F=480.2+49*7.9 N \\F=867.3 N\\\)

So, F= 867.3 N is required.

Therefore, the trampoline has to apply a force of 867.3 N to accelerate the acrobat straight up at \(7.9 m/s^2\).

2.2 mol of monatomic gas A initially has 4500 J of thermal energy. It interacts with 2.9 mol of monatomic gas B, which initially has 8100 J of thermal energy. Part A : Gas B has the higher initial temperature. Part 2 : the final thermal energy of gas A is 12600 J. Part 3 : The final thermal energy of gas B is also 12600 J.

Part A : Gas B has the higher initial temperature.

Part B: The final thermal energy of gas A can be calculated using the principle of energy conservation. The total initial thermal energy is given as 4500 J, and since there is no external work done on the system, the change in thermal energy is equal to the heat transferred.

We can set up the equation as follows:

ΔE = Q

Where ΔE is the change in thermal energy and Q is the heat transferred.

Since the two gases are interacting, they will reach thermal equilibrium. This means that the final thermal energy of gas A will be equal to the sum of the initial thermal energies of both gases:

Ef(A) = Ei(A) + Ei(B)

Ef(A) = 4500 J + 8100 J = 12600 J

Therefore, the final thermal energy of gas A is 12600 J.

Part C: Following the same reasoning as above, the final thermal energy of gas B will also be equal to the sum of the initial thermal energies of both gases:

Ef(B) = Ei(A) + Ei(B)

Ef(B) = 4500 J + 8100 J = 12600 J

Therefore, the final thermal energy of gas B is also 12600 J.

The position vector of the particle is r(t) = (4t^3/3 - cos(t) + C1)i + (-cos(t) + C2)j + (sin(2t)/2 + C3)k.

To find the position vector of a particle given its acceleration, initial velocity, and initial position, we integrate the acceleration function twice.

In the given problem, the acceleration function is a(t) = 12ti + sin(t)j + cos(2t)k. Integrating with respect to time, we obtain the velocity function v(t) = 6t^2i - cos(t)j + sin(2t)/2k, where C1 is the constant of integration.

Integrating the velocity function with respect to time once again, we get the position function r(t) = (2t^3 - cos(t) + C1)i - sin(t)j + sin(2t)/2 + C2k, where C2 is the constant of integration.

Given the initial velocity v(0) = i, we can find the constant C1 by substituting t = 0 into the velocity function. Therefore, C1 = 0.

Given the initial position r(0) = j, we can find the constant C2 by substituting t = 0 into the position function. Therefore, C2 = 0.

Thus, the position vector of the particle is r(t) = (4t^3/3 - cos(t))i - cos(t)j + sin(2t)/2k.

To graph the path of the particle, we can use a computer to plot the position vector as a function of time. By varying the time, we can visualize the trajectory of the particle in three-dimensional space.

Explanation:

The acceleration due to gravity on the surface of the asteroid is directly proportional to the mass of the asteroid and inversely proportional to the square of the distance from the center of the asteroid.

Therefore, it varies depending on the asteroid's size, shape, and composition.

Acceleration is the rate of change of velocity over time. A change in velocity, which can be either a change in magnitude or direction or both, results in acceleration.

It is measured in units of meters per second squared (m/s²) or centimeters per second squared (cm/s²).

Gravity is a fundamental force in physics that exists between any two objects in the universe.

The force of gravity pulls all objects with mass toward each other.

Gravity's strength depends on the mass of the two objects and the distance between them.

An asteroid is a small rocky or metallic object in space that orbits the sun. They are usually composed of rock, metal, or a combination of the two.

They vary in size from a few meters to hundreds of kilometers in diameter.

Most asteroids are found in the asteroid belt between Mars and Jupiter, although some are also found in other regions of the solar system.

The net force on the body is 7N towards Left.

As we know, that the force is vector quantity so will have magnitude as well as direction.

While calculating the net force we have to keep in mind that the direction of the applied force is important to note.

In our case, 15N force is applied towards the left direction.

A force of 8N is applied toward the right direction.

These forces will collide with each other in order to cancel each other they both have opposite direction.

Let say the net force on the body is F, the net force on the body will be,

F = 15N - 8N

F = 7N.

We know the magnitude. Now, we have to find the direction, on collision the force with bigger magnitude will dominate over the force with smaller magnitude. hence the direction of the net force will be in the direction of the Bigger force, i.e. Left Direction.

One statement that is not true is that UV radiation is a type of electromagnetic radiation. It is also a type of ionizing radiation. UV radiation is actually a form of non-ionizing radiation.

UV radiation, or ultraviolet radiation, is a type of electromagnetic radiation that falls between visible light and X-rays on the electromagnetic spectrum. It is often categorized into three types: UVA, UVB, and UVC. Unlike ionizing radiation, such as X-rays and gamma rays, which have enough energy to remove tightly bound electrons from atoms or molecules, UV radiation lacks the necessary energy to ionize atoms or molecules. Instead, it primarily interacts with the outermost electrons of atoms or molecules, leading to chemical reactions and causing biological effects.

UV radiation is commonly associated with sunlight and has various effects on living organisms and materials. It can cause sunburn, premature aging of the skin, and an increased risk of skin cancer. Exposure to excessive UV radiation can also damage the eyes and impair the immune system. It is important to protect oneself from excessive UV exposure by wearing sunscreen, protective clothing, and sunglasses.

Answer:

The correct option is;

(B) \(\underset{P}{\rightarrow}\) is conserved, K Not conserved

Explanation:

From the diagram related to the question and from the question, we have;

m₁ = m₂ = 2 kg

v₁ = 4 m/s, v₂ = -2 m/s, v₃ = 1 m/s, therefore, we have;

The total initial momentum of the system = m₁ × v₁ + m₂ × v₂

m₁ (v₁ + v₂) = 2×(4 - 2) = 4 kg·m/s

The total final momentum of the system = m₁ × v₃ + m₂ × v₃ = 2 ×1 +2 ×1  = 4 kg·m/s

Given that the total initial momentum = The total final momentum, we have that the momentum, p, is conserved

The kinetic energy of the system before collision  = 1/2×m₁×v₁² + 1/2×m₂×v₂²

∴ The kinetic energy of the system before collision  = 1/2*2*(4)² + 1/2*2*(-2)² = 20 J

∴ The kinetic energy of the system after collision  = 1/2×m₁×v₃² + 1/2×m₂×v₃²

1/2*2*(1)² + 1/2*2*(1)² = 2 J

The kinetic energy of the system before collision ≠ The kinetic energy of the system after collision

Therefore, the kinetic energy of the system is not conserved.

If the velocities of object X and object Y after collision is the same (inelastic collision), then only momentum is conserved but if the velocities of both objects after collision are different (elastic collision), then both momentum and kinetic energy are conserved.

According to principle of conservation of linear momentum, the total momentum before and after collision is conserved.

For inelastic collision, only momentum is conserved while kinetic energy is not conserved.

\(m_1u_1 \ + \ m_2u_2 = v(m_1 + m_2)\)

\(\frac{1}{2} m_1u_1^2 \ + \frac{1}{2} m_2u_2^2 = \frac{1}{2}v^2(m_1+m_2)\)

For elastic collision, both momentum and kinetic energy are conserved;

\(m_1u_1 \ + \ m_2u_2 =m_1v_1 \ + \ m_2v_2\)

\(\frac{1}{2} m_1u_1^2 \ + \frac{1}{2} m_2u_2^2 = \frac{1}{2}m_1v_1^2 \ +\ \frac{1}{2}m_2v_2^2\)

Thus, we can conclude that, if the velocities of object X and object Y after collision is the same (inelastic collision), then only momentum is conserved but if the velocities of both objects after collision are different (elastic collision), then both momentum and kinetic energy are conserved.

Electric and hydrogen are promising alternative energy sources for transportation, offering benefits such as reduced emissions and lower operating costs, although they also face challenges related to infrastructure and production methods.

Electric and hydrogen are two promising alternative energy sources for transportation that have gained significant attention in recent years. Here are some key points about each:

Electric Vehicles (EVs): EVs use electricity stored in batteries to power an electric motor.

They offer several advantages, including zero tailpipe emissions, reduced dependence on fossil fuels, and lower operating costs compared to traditional internal combustion engine vehicles.

The growth of EV infrastructure and advancements in battery technology have contributed to their increasing popularity.

Hydrogen Fuel Cell Vehicles (FCVs): FCVs use hydrogen gas to generate electricity through a chemical reaction in a fuel cell, which then powers an electric motor. FCVs produce zero tailpipe emissions since the only byproduct is water vapor.

Hydrogen fuel can be refueled quickly, similar to traditional gasoline vehicles, providing a longer driving range compared to battery-powered EVs.

Both electric and hydrogen vehicles have their own set of challenges. For EVs, limited charging infrastructure and range anxiety remain concerns, although they have been improving over time.

Hydrogen FCVs face challenges related to hydrogen production, storage, and distribution infrastructure.

Additionally, the overall environmental impact of these alternative energy sources depends on the methods used for electricity or hydrogen production.

The adoption of alternative energy sources for transportation is a complex and evolving field.
