Complete Question

Suppose a wireless charging system of an electric toothbrush. The charger has Solenoid 1 with 800 turns and the toothbrush has Solenoid 2 with 150 turns. The current in the charger is 220 mA and the corresponding average magnetic flux through Solenoid 2 is 0.056 Wb. What is the mutual inductance of the pair of the solenoids?

Answer:

The value is \(M = 38.2 \ H\)

Explanation:

From the question we are told that

     The number of turns of solenoid 1 is \(N_1 = 800\)

     The  number of turns for solenoid 2 is  \(N_2 = 150 \ turns\)

     The current in the charger is  \(I = 220 \ mA = 220 *10^{-3} \ A\)

      The  magnetic flux through solenoid 2 is  \(\phi = 0.056 \ Wb\)

Generally mutual inductance is mathematically represented as

        \(M = \frac{N_2 * \phi }{ I }\)

=>     \(M = \frac{150 * 0.056 }{ 220 *10^{-3} }\)

=>    \(M = 38.2 \ H\)

What is hydrostatic pressure meaning?

Hydrostatic pressure refers to the pressure that any fluid in a confined space exerts. If the fluid is in a container, there will be some pressure on the wall of that container.

What is hydrostatic pressure used for?

Hydrostatic pressure is one reason (along with the lack of oxygen) why it's not safe for humans to travel unprotected in space. You rely on hydrostatic pressure to keep your lungs at the right inflation and to keep the water in your body from vaporizing.

How is hydrostatic pressure calculated?

The pressure in a liquid at a given depth is called hydrostatic pressure. This can be calculated using the hydrostatic equation:

P = rho * g * d, where P is the pressure, rho is the density of the liquid, g is gravity (9.8 m/s^2) and d is the depth (or height) of the liquid.

Thus, the pressure on the bottom when water is added to fill the pipe to its top is 180kPa.

Explanation:

The maximum distance of the spring is nearly 0.31 m. Option (E) is correct.

Given:

Mass of the ball, m = 0.20 kg

Acceleration due to gravity, a=  9.81 m/s²

Initial height, h = 30 cm = 0.30 m

Spring constant, k = 25 Nm

The potential energy is given by:
P = mg(h+x)

P = 0.20 kg × 9.81 × (0.30 + x)

The potential energy of the spring is:

P₁= 0.5 ×  k ×  x²

P₁ = 0.5 × 25 × x²

The potential energies of the spring and ball are equal. Equating the energies:

0.20 kg × 9.81 × (0.30 + x) = 0.5 × 25 × x²

12.5x² - 1.962x - 0.5886 = 0

In order to draw a vector in the coordinate system, we can follow these steps:

1. Draw the initial point of the vector.

2. Draw the end point of the vector.

3. Create an arrow starting at the initial point and ending at the end point.

For example, let's use a vector that starts at (0, 0) and ends at (3, 4):

- The resistance of the first resistor (R₁) is 12 Ω.

- The electromotive force (EMF) of the battery is 18 V.

- The internal resistance of the battery is 12 Ω.

To solve the given problem, we can apply Kirchhoff's laws and Ohm's law to determine the resistance of the first resistor (R₁) and the electromotive force (EMF) and internal resistance of the battery.

Let's start by calculating the resistance of the first resistor (R₁):

1. Apply Ohm's law to find the voltage drop across the external circuit:

  V = I * R

  V = 1 A * 6 Ω

  V = 6 V

2. The voltage drop across the external circuit is equal to the EMF minus the voltage drop across the internal resistance of the battery:

  V = E - Ir

  6 V = E - (1 A * r)   (where r is the internal resistance of the battery)

3. We also know that the EMF of the battery is the sum of the voltage drops across each cell in the battery:

  E = 6 cells * 3 V/cell

  E = 18 V

4. Substitute the value of E in the equation from step 2:

  6 V = 18 V - r

  r = 12 Ω

Therefore, the resistance of the first resistor (R₁) is 12 Ω.

These are the absorption of energy by electrons.

What is electron?

The electrons are an atom's negatively charged building blocks. An atom's entire population of electrons comes together to create a negative charge that balances out the positive charge of the protons in the atomic nucleus. Electrons are incredibly little compared to all the other atom's parts.

What is atom ?

A negatively charged electron or electrons surround the core nucleus of an atom, which is made up of one or more of them. Protons and neutrons, which are comparatively heavy particles, are present in the positively charged nucleus in one or more quantities.

We call the shell is complete if they have 2 electrons ( in the first shell only) called duplet or 8 electrons ( in any shell except the first ) called octate.

1) In the first figure, the duplet is complete. ( 2 electrons in the first shell). But the second one has only 4 and octate is incomplete, still the third shell has one electron. So this is the excited state.

2) In second picture, first shell has only one electron and duplet is not complete. Still the second shell has two electrons. This is the excited state.

3) In third picture, first shell has completed duplet and second shell has completed the octate. But third shell is not completed. Still the forth shell has three electrons. So, this is also the excited state.

4) Forth picture has complete duplet and complete octate. Higher shells have no electrons. So, this is not excited state.

5) In fifth picture also, atom has completed duplet and octate. Higher orbit ( third ) has two electrons. Though, the octate is complete, higher shells have no electrons. So this is not a excited state.

Therefore, these are the absorption of energy by electrons.

The nature of the image formed by the convex lens is virtual, the position of the image is 30 cm away from the lens on the same side as the object, and the size of the image is twice the size of the object. The magnification is 2, meaning the image is magnified.

Given:

Object height (h) = 5 cm

Focal length of the convex lens (f) = 10 cm

Object distance (u) = 15 cm (positive since it's on the same side as the incident light)

To determine the nature, position, and size of the image, we can use the lens formula:

1/f = 1/v - 1/u

Substituting the given values:

1/10 = 1/v - 1/15

To simplify the equation, we find the common denominator:

3v - 2v = 2v/3

Simplifying further:

v = 30 cm

The image distance (v) is 30 cm. Since the image distance is positive, the image is formed on the opposite side of the lens from the object.

To find the magnification (M), we use the formula:

M = -v/u

Substituting the values:

M = -30 / 15 = -2

The magnification is -2, indicating that the image is inverted and twice the size of the object.

It is dropped off a balcony Sandra standing on the ground below the balcony, catches the ball by exerting a 15.5N force upwards on the ball.

We need to find the acceleration of the ball while Aisha is catching it.

The net force acting on the ball is given by :

F = ma

In this case, when the ball is accelerating downward,

mg-F=ma

a is the acceleration of the ball and g is the acceleration due to gravity

So,

\(a=\dfrac{mg-F}{m}\\\\a=\dfrac{0.75\times 9.81-15.5}{0.75}\\\\a=-10.86\ m/s^2\)

A negative sign shows that the ball is accelerating in a downward direction.

If the new distance is, r' = 3r

The new force is given by :

\(F'=G\dfrac{m_1m_2}{r'^2}\\\\F'=G\dfrac{m_1m_2}{(3r)^2}\\\\F'=\dfrac{1}{9}\times G\dfrac{m_1m_2}{r^2}\\\\F'=\dfrac{F}{9}\)
