A substance or thing that creates a magnetic field is called a magnet. The most noteworthy characteristic of a magnet—a force that pulls on other ferromagnetic elements, such as iron, steel, nickel, cobalt, etc.—as well as the ability to attract or repel other magnets—is caused by this invisible magnetic field. An object made of a substance that has been magnetized and produces its own persistent magnetic field is referred to as a permanent magnet. A common example is a refrigerator magnet used to keep notes on the door of the refrigerator. Ferromagnetic materials are those that can be magnetized and are also those that are powerfully drawn to a magnet (or ferrimagnetic).

Explanation:

The moon does not have a strong magnetic field. This  is the most likely reason for the difference between how the compass works on Earth and on the moon. Hence option C is correct.

The magnetic impact on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field. A force perpendicular to the charge's own velocity and the magnetic field acts on it while the charge is travelling through a magnetic field The magnetic field of a permanent magnet pulls on ferromagnetic substances like iron and attracts or repels other magnets. Paramagnetism, diamagnetism, and antiferromagnetism are three additional magnetic effects that a nonuniform magnetic field may have on "nonmagnetic" materials, albeit these forces are often so minute that they can only be detected by laboratory equipment. Electric currents, such those utilised in electromagnets, and electric fields that change in time produce magnetic fields that surround magnetised objects.

just finished cumulative exam and this was a question

The magnitude of acceleration of the charged plastic bead can be calculated by using Coulomb's Law which  is -6.21 m/s^2.

According to Coulomb's Law, the force between two charged particles is given by the equation

F = k*(q1*q2)/(r^2), where k is the Coulomb's constant, q1 and q2 are the charges of the two particles, and r is the distance between the two particles.

In this case, k = 8.99 x 10^9 Nm^2/C^2, q1 = -4.0 nC, q2 = 8.0 nC, and r = 2.4 cm.

Using the equation, the magnitude of the force between the two particles is calculated as F = 8.99 x 10^9 x (-4.0 x 10^-9)(8.0 x 10^-9) / (2.4 x 10^-2)^2 = -14.9N.

The acceleration of the plastic bead can then be calculated using Newton's Second Law of Motion

F = ma.

Therefore, a = F/m, where m is the mass of the bead. In this case, the mass of the plastic bead is 2.4 g.

So, the magnitude of acceleration of the plastic bead is a = -14.9N/2.4g = -6.21 m/s^2.

Therefore, the magnitude of acceleration of the plastic bead is -6.21 m/s^2.

The speed of sound at 21∘C is approximately 344.1 m/s. For a frequency of 3 kHz, the wavelength is approximately 0.11 meters.

The formula for the speed of sound in air is given by,

v = 331.5 + 0.6T

where v is the speed of sound in meters per second, and T is the temperature in degrees Celsius.

Plugging in T = 21∘C,

v = 331.5 + 0.6(21) = 331.5 + 12.6 = 344.1 m/s

The wavelength of a sound wave is,

The answer is : t  = 2.64 [s].

On the planet Koozebane, a pebble is dropped from height h and it falls to the surface in time t. The acceleration on the planet Koozebane is given as 3.100 m/s², and the height is given as 4.400 m.

We have to determine the time t.Therefore, we will use the following kinematic equation for freefall motion with no initial velocity:

h = ½ at² + vot

Where:v₀ = 0 m/st ,h = 4.400 m

(The height from which the pebble is dropped)

a = 3.100 m/s²

Substituting these values in the equation, we get

:4.400 = ½ (3.100) t²

After rearranging, we get:

t = √(2h/a)t

= √[2 × 4.400/3.100]t

= √[6.9677]t

= 2.64 s

Therefore, the time taken for the pebble to fall to the surface on the planet Koozebane is 2.64 s.

The efficiency of the engine is 1.57%.

Efficiency is a measure of how well a system converts input energy into useful output energy. It is calculated as the ratio of useful output energy to the total input energy.

To find the efficiency of the engine, we need to calculate the work done by the engine and the heat absorbed from the reservoirs during the cycle.

Step 1: Isothermal expansion at 325 K from 16.1 L to 31.5 L

Since this is an isothermal process, the temperature remains constant at 325 K. The work done by the engine during this process is given by:

W1 = nRT ln(V2/V1)

where n is the number of moles of the gas, R is the universal gas constant, and T is the temperature in kelvin.

n = 1 mol

R = 8.314 J/mol/K

T = 325 K

V1 = 16.1 L

V2 = 31.5 L

W1 = (1 mol)(8.314 J/mol/K)(325 K) ln(31.5 L/16.1 L)

W1 = 4527.6 J

The heat absorbed from the reservoir during this process is given by:

Q1 = W1 = 4527.6 J

Step 2: Cooling at constant volume to 163 K

Since this is a constant volume process, no work is done by the engine. The heat absorbed from the reservoir during this process is given by:

Q2 = nCvΔT

where Cv is the heat capacity at constant volume and ΔT is the change in temperature.

n = 1 mol

Cv = 21 J/K

ΔT = 163 K - 325 K = -162 K

Q2 = (1 mol)(21 J/K)(-162 K)

Q2 = -3402 J

Step 3: Isothermal compression to its original volume of 16.1 L

Since this is an isothermal process, the temperature remains constant at 163 K. The work done on the engine during this process is given by:

W3 = -nRT ln(V2/V1)

where V1 = 31.5 L and V2 = 16.1 L.

n = 1 mol

R = 8.314 J/mol/K

T = 163 K

V1 = 31.5 L

V2 = 16.1 L

W3 = -(1 mol)(8.314 J/mol/K)(163 K) ln(16.1 L/31.5 L)

W3 = -4456.5 J

The heat released to the reservoir during this process is given by:

Q3 = -W3 = 4456.5 J

Step 4: Heating at constant volume to its original temperature of 325 K

Since this is a constant volume process, no work is done by the engine. The heat released to the reservoir during this process is given by:

Q4 = nCvΔT

where Cv is the heat capacity at constant volume and ΔT is the change in temperature.

n = 1 mol

Cv = 21 J/K

ΔT = 325 K - 163 K = 162 K

Q4 = (1 mol)(21 J/K)(162 K)

Q4 = 3402 J

The net work done by the engine is given by the sum of the work done during steps 1 and 3:

Wnet = W1 + W3 = 4527.6 J - 4456.5 J = 71.1 J

The net heat absorbed from the reservoirs is given by the sum of the heat absorbed during steps 1 and 2, and the sum of the heat released during steps 3 and 4:

Qnet = Q1 + Q2 + Q3 +Q4 = 4527.6 J - 3402 J + 4456.5 J - 3402 J = 2179.1 J

The efficiency of the engine is given by:

η = Wnet/Q1 = 71.1 J/4527.6 J = 0.0157 or 1.57%

Therefore, the efficiency of the engine is 1.57%.

Option D. 5.45 Ω

Explanation:

From the question given above, the following data were obtained:

Resistance 1 (R₁) = 10 Ω

Resistance 2 (R₂) = 20 Ω

Resistance 3 (R₃) = 30 Ω

Voltage (V) = 120 V

Equivalent resistance (R) =?

The equivalent resistance can be obtained as follow:

Explanation:

Given the following data;

To find the final volume, we would use Boyle's law;

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

PV = K

\( P_{1}V_{1} = P_{2}V_{2} \)

Making V2 the subject of formula, we have;

\( V_{2} = \frac {P_{1}V_{1}}{P_{2}} \)

Substituting the values into the formula, we have;

\( V_{2} = \frac {18.9 * 3.4}{2.2} \)

\( V_{2} = \frac {64.26}{2.2} \)

Final volume, V2 = 29.21 m³

The smallest sound power output of the airplane motor that can be listened to on the ground is  6.73 × 10^-6 W which has the lowest-intensity sound that is still loud and has an intensity of  10^-12 W/m^2.

The intensity of sound =  10^-12 W/m^2

Altitude =  6,500 m.

Calculate the smallest sound energy output of an aircraft motor that can be heard on the ground is done by using the formula:

I = P/(4πr^2)

Pythagoras' theorem is used for calculating the distance

d = (\(\sqrt{6500^2 + R^2}\))

I = 10^-12 W/m^2

d = \(\sqrt{6500^2 + R^2}\)

d = 6500 m

P/(4πd^2) = I

\(P/(4π(6500)^2) = 10^-12 W/m^2\)

\(P = 4π(6500)^2 × 10^-12 W\)

P = 6.73 × 10^-6 W

Answer:

The main difference between these types of motion is that circular motion is a special case of rotational motion, where the distance between the body’s centre of mass and the axis of rotation remains fixed.

Rotational motion is based around the idea of rotation of a body about its center of mass. In rotational motion, the axis of rotation and centre of mass could change whereas in circular motion, the axis of rotation and centre of mass does not change.

Circular motion is a movement of an object along the circumference of a circle or rotation along a circular path and can either have a constant angular rotation rate and constant speed, or it can exist with a changing rate of rotation.
