So, the total energy value that has been transferred by work is 32 kJ.

Hi ! In this question, I will help you. Work is the amount of force exerted to cause an object to move a certain distance from its starting point. In physics, the amount of work will be proportional to the increase in force and increase in displacement. Amount of work can be calculated by this equation :

\( \boxed{\sf{\bold{W = F \times s}}} \)

With the following condition :

Now, because in this question, the "s" is not directly known, whereas it is known that the initial velocity is zero, the object has an acceleration, and is moving in certain time intervals. Then, use this formula to find the value of "s" !

\( \boxed{\sf{\bold{s = \frac{1}{2} \times a \times t^2}}} \)

With the following condition :

We know that :

What was asked :

Step by Step :

\( \sf{F = m \times a} \)

\( \sf{F = 10 \times 4} \)

\( \sf{\bold{F = 40 \: N}} \)

\( \sf{s = \frac{1}{2} \times a \times t^2} \)

\( \sf{s = \frac{1}{\cancel 2} \times \cancel 4 \:_2 \times 20^2} \)

\( \sf{s = 2 \times 400} \)

\( \sf{\bold{s = 800 \: m}} \)

\( \sf{W = F \times s} \)

\( \sf{W = 40 \times 800} \)

\( \boxed{\sf{W = 32,000 \: J = 32 \: kJ}} \)

So, the total energy value that has been transferred by work is 32 kJ.

C. Electrons move away from the negative end of a battery and then

through the circuit toward the positive end of the battery.

The energy stored in the magnetic field of the coil is approximately 69.12 J.

Energy = (1/2) * L * I^2

where L is the inductance of the coil and I is the current flowing through the coil.

Given:

Inductance (L) = 15 mH = 15 * 10^-3 H

Resistance (R) = 0.25 Ω

Potential difference (V) = 24 V

To find the current flowing through the coil, we can use Ohm's Law:

\(V = I * RI = V / RI = 24 / 0.25I = 96 A\)

Now, we can calculate the energy stored in the magnetic field:

\(Energy = (1/2) * L * I^2Energy = (1/2) * 15 * 10^-3 * (96)^2Energy = 0.5 * 15 * 10^-3 * 9216Energy = 69.12 J\)

Therefore, the energy stored in the magnetic field of the coil is approximately 69.12 J.

Explanation:

For every action (or force), there is an equal and opposite action (or force).

Explanation:

Since the mast is a conductor and connected to the plastic so charge transfer takes place between the mast and the tube because the mast is connected to the ground with wire which is called grounded which means its potential is 0 equal to the ground so that charge can transfer from plastic tube to the ground. This is why the wire is used to connect the metal mast to the Earth.

A nearby passing star was able to gravitationally pull the two gas giants toward the outer parts of the solar system by countering the gravity of the early protosun.

Gravity is a force that acts between two masses and attracts them towards each other. It is the force that keeps the planets in orbit around the sun and the moon in orbit around the Earth. The strength of the gravitational force between two objects depends on their masses and the distance between them. The basic idea behind gravity was first described by Sir Isaac Newton in his law of universal gravitation, which states that every object in the universe attracts every other object with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.

The simple evaluation technique of VT is based on the idea that threshold voltage (VT) is equal to the gate voltage at which the inversion layer charge density is zero.

Explanation:

The simple evaluation technique of VT is based on the idea that threshold voltage (VT) is equal to the gate voltage at which the inversion layer charge density is zero. When measuring the threshold voltage of a PMOS device using the VTP method, a positive voltage is applied to the drain terminal and a negative voltage is applied to the source terminal. This causes the transistor to be turned off since the body is positively biased and the PMOS channel will not conduct current. A negative voltage is then applied to the gate, which is gradually increased.

The device is turned on when the threshold voltage is reached, and the inversion layer charge density is no longer zero. Therefore, the gate voltage at which the device is turned on is equal to the threshold voltage (VT). Thus, the VTP measurement technique for PMOS devices is based on the simple evaluation technique of VT, which is the gate voltage at which the inversion layer charge density is zero.

The slope of the line tangent to the polar curve r = 2θ² when θ = π is 10π.

The slope of the line tangent to the polar curve r = 2θ² when θ = π can be found using the polar form of the derivative dr/dθ. First, we need to find dr/dθ:

dr/dθ = d(2θ²)/dθ = 4θ

Now, we need to use the formula for the slope of the tangent line in polar coordinates:

dy/dx = (r * (dr/dθ) + θ * dr/dθ) / (r - θ * (dr/dθ))

Substitute the given value of θ (π) and the expression for dr/dθ (4θ) into the formula:

dy/dx = [(2(π)²) * (4π) + π * (4π)] / [(2(π)²) - π * (4π)]

Simplify the expression:

dy/dx = (20π³) / (2π²)

Cancel out π²:

dy/dx = 10π

So, the slope of the line tangent to the polar curve r = 2θ² when θ = π is 10π.

To find the moment of inertia of the system, we can use the formula for the moment of inertia of a rod rotating about an axis perpendicular to it:

I = (1/12) * m * L^2

Where I is the moment of inertia, m is the mass of the rod, and L is the length of the rod.

Since the rod is massless, we only need to find the moment of inertia of the two point masses at the ends of the rod. Since they are equal, we can divide the total moment of inertia by 2 to get the moment of inertia of one of them.

To find the mass of each point mass, we can use the fact that the kinetic energy of the system is equal to the rotational kinetic energy of the two masses:

KE = (1/2) * I * w^2

Where KE is the kinetic energy, I is the moment of inertia, and w is the angular velocity.

Substituting the given values, we get:
36 J = (1/2) * I * (3 rad/s)^2

Solving for I, we get:
I = (2 * KE) / w^2
  = (2 * 36 J) / (3 rad/s)^2
  = 8 kg * m^2

Since we have two equal point masses, the moment of inertia of each one is:
I/2 = 4 kg * m^2

Therefore, the value of the moment of inertia of the system is 4 kg * m^2.

To calculate the density of the metal cube, we need to use the formula:

density = mass/volume

Since the cube is a perfect cube, we can find its volume by using the formula:

volume = side^3

So, volume = 3.21 cm x 3.21 cm x 3.21 cm = 32.79 cm^3

Now, we can substitute the values in the formula:

density = 0.347 kg / 32.79 cm^3

Density = 10.57 g/cm^3

To identify the metal, we need to compare its density with the known densities of various metals. According to the periodic table, the closest density to 10.57 g/cm^3 is that of copper, which is 8.96 g/cm^3. Therefore, it is unlikely that the metal is copper. The closest density to 10.57 g/cm^3 after copper is that of tungsten, which is 19.25 g/cm^3. Therefore, the metal is more likely to be tungsten.

To determine the location of the image formed by a converging lens, we can use the lens formula:

1/f = 1/d_o + 1/d_i,

where f is the focal length of the lens, d_o is the object distance, and d_i is the image distance.

Given:

Focal length of the lens (f) = 6.5 cm,

Object distance (d_o) = 28 cm.

We can rearrange the lens formula to solve for the image distance:

1/d_i = 1/f - 1/d_o.

Substituting the given values:

1/d_i = 1/6.5 - 1/28.

To find the value of d_i, we calculate the right-hand side of the equation and then take the reciprocal:

1/d_i = (28 - 6.5) / (6.5 * 28).

1/d_i = 21.5 / 182.

d_i = 182 / 21.5.

d_i ≈ 8.47 cm.

The positive sign indicates that the image is formed on the opposite side of the lens from the object. Therefore, the image is located approximately 8.47 cm in front of the lens.

According to Plumbing 101 principles governing blood flow through the vessels, the statement "Flow depends on pressure difference, but not the absolute pressure" is true.

In the context of Plumbing 101 principles, blood flow through the vessels can be understood by applying the laws of fluid dynamics. According to these principles, the statement that holds true is that flow depends on pressure difference, but not the absolute pressure.

Pressure difference refers to the variance in pressure between two points in a fluid system. In the case of blood flow, it refers to the pressure difference between the point of origin (such as the heart) and the destination point (such as organs or tissues). The pressure difference creates a driving force for blood to flow from higher pressure regions to lower pressure regions.

While the absolute pressure at the origin and destination points may affect the overall pressure difference, it does not directly impact the flow rate of blood. Flow is primarily determined by the pressure difference rather than the absolute pressure at the specific points. Other factors, such as the diameter of the vessel, viscosity of the blood, and the resistance offered by the vessel walls, also influence blood flow.
