The largest force that an energy source containing 100 joules can exert continuously over a distance of 25 meters is 25 Newtons (N).

This means that the energy source can exert a force of 25 N for every 100 joules of energy it contains.

The equation for calculating force is Force = Work/Distance (F = W/D).

So, in this case, Force = 100 Joules/25 Meters = 25 Newtons.

Force is a push or pull exerted on an object. It is measured in units of Newtons (N) and is calculated by dividing the amount of work done by the distance over which the work is done. Force can be used to cause an object to accelerate, change its direction, or change its shape.

Explanation:

Given that,

The mass of a bullet, m = 50 g = 0.05 kg

The velocity of the bullet, v = 720 km/hr = 477.77 m/s

We need to find the kinetic energy of the bullet​. The kinetic energy of an object is due to its motion. It can be given by the formula as follows :

[tex]K=\dfrac{1}{2}mv^2\\\\=\dfrac{1}{2}\times 0.05\times 477.77 ^2\\\\K=5706.6\ J[/tex]

So, the required kinetic energy of the bullet is equal to 5706.6 J.

The kinetic energy will the ball acquire from the bat is 1.0x10^1 joules or 100 joules. This calculation is based on the equation Energy = Force x Distance, which is a fundamental equation of physics.

The kinetic energy of the ball is equal to the work done by the bat on the ball. The work done by the bat on the ball is equal to the force applied by the bat multiplied by the distance the bat stays in contact with the ball. Therefore, the kinetic energy of the ball would be equal to 2.0x10^4 newtons multiplied by 5.0x10^-3 meters, which is equal to 1.0x10^1 joules or 100 joules.

This calculation is based on the equation of  Energy which is  Force x Distance. Additionally, this equation can be rearranged to solve for any of the variables, depending on what is known and what needs to be calculated. In this case, the known variables were the force applied by the bat and the distance the bat stayed in contact with the ball, and the variable that needed to be calculated as the kinetic energy of the ball.

Force is positive if the mass accelerates downward. Use the formula T = M x A to determine the tension in the rope.

That direction is the pull that is referred to as tension. As a result, the tension will point toward the string or rope and away from the mass.

A mass suspended by a string is pulled upward by the string, exerting an upper force that shifts the tension to the upper side.

For instance, you should know that T = 9g x 2m/s2 = 18gm/s2 or 18N when trying to calculate T in a straightforward pulley system with a linked mass of 9g and an upward acceleration of 2m/s2 (newtons). The direction in which a string expands changes when it passes over an ideal massless pulley, but the string's tension is unaffected.

Explanation:

The magnetic flux through the loop is approximately 1.317 × [tex]10^{(-5)[/tex]T·m².

To calculate the magnetic flux through a loop, we use the formula:

Φ = B × A × cos(θ)

Where:

Φ is the magnetic flux

B is the magnetic field strength

A is the area of the loop

θ is the angle between the magnetic field and the normal to the loop

Given:

Magnetic field strength (B) = 3.09 × [tex]10^{(-4)[/tex] T (east direction)

Area of the loop (A) = 0.0471 m²

The loop faces directly northeast

To find the angle θ,  determine the angle between the magnetic field direction (east) and the normal to the loop (northeast).

Since the loop faces northeast, the angle between the normal to the loop and the east direction is 45 degrees (90 degrees divided by 2).

Now calculate the magnetic flux:

Φ = B  × A  × cos(θ)

Φ = (3.09 × [tex]10^{(-4)[/tex] T) × (0.0471 m²) × cos(45°)

Using the value of cos(45°) as 0.7071:

Φ = (3.09 × [tex]10^{(-4)[/tex] T) × (0.0471 m²) ×0.7071

Φ = 1.317 × [tex]10^{(-5)[/tex] T·m²

The correct option is B, The electron's speed at f is equal to its speed at i.

Electrons are subatomic particles that are found in atoms. They are the negatively charged particles that orbit the nucleus of the atom, and they have an extremely small mass. Electrons travel at different speeds depending on their energy level. At their lowest energy level, electrons move at an extremely slow speed, about one thousandth of the speed of light. As the electrons gain energy, their speed increases.

In a vacuum, when electrons have the highest energy level, they can travel at a speed of nearly the speed of light, which is around 186,000 miles per second. In a vacuum, the electrons would have the same speed regardless of their mass. Electrons also move slower inside a material, such as a metal, due to the presence of other atoms. Electrons in metals usually move at a speed of about 1/10th the speed of light. This slower speed is due to the electrons having to pass through energy barriers created by the other atoms in the metal. In general, electrons are very fast particles that can travel at speeds up to nearly the speed of light.
