The correct option is;

(b) The end A of the solenoid behaves like a north pole

Explanation:

According to Lenz's law we have that the induced emf direction in the solenoid due to the rapid introduction of the bar magnet will be such that the electric current induced will have a resultant magnet field that will  oppose to the movement of the north pole of the bar magnet that resulted in the magnetic field

Therefore, the opposing magnetic pole to the north pole of a magnet is a north pole and the solenoid end A will act like the north pole.

To determine if the manufacturer's label is consistent with your calculated equivalent capacitance of 0.72 μF ± 0.08 μF, we need to compare the ranges of the values.

1. Determine the manufacturer's label range:
The manufacturer labeled the capacitor as 0.5 μF ± 10%. To find the range, we will calculate 10% of 0.5 μF.

0.5 μF * 10% = 0.05 μF

The range of the manufacturer's label is 0.5 μF ± 0.05 μF, meaning it could be between 0.45 μF and 0.55 μF.

2. Determine your calculated range:
You calculated the equivalent capacitance as 0.72 μF ± 0.08 μF. This means your calculated range is between 0.64 μF and 0.8 μF.

3. Compare the ranges:
Manufacturer's range: 0.45 μF to 0.55 μF
Your calculated range: 0.64 μF to 0.8 μF

Since there is no overlap between the two ranges, the manufacturer's label of 0.5 μF ± 10% is not consistent with your calculated result of 0.72 μF ± 0.08 μF.

The distance between first airplane and second airplane after 1.8 hours of their departure is 1598.22 meters.

The cosine formula for vector addition is -

|R|² = |A|² + |B|² + 2AB cosφ

Where - φ is the angle between vectors A and B.

Given is two airplanes that leave the airport at same time. The velocity of the first airplane is 690 m/h at a heading of 68.5°. The velocity of the second airplane is 590 m/h at a heading of 156°.

The length of the position vector of first airplane →

|OA| = velocity x time = 690 x 1.8 = 1242 miles.

The length of the position vector of second airplane →

|OB| = velocity x time = 590 x 1.8 = 1062 miles

Angle between vectors OA and OB →

φ = 156° - 68.5° = 87.5°

In the triangle ΔOAB, using the triangle law of vector addition, we get →

OA + AB = OB

AB = OB - OA

AB = OB + (- OA)

Now, using the formula for resultant of addition of two vectors →

AB² = (OB)² + (- OA)² + 2(OA)(- OB) cosφ

AB² = OB² + OA² + - 2(OA)(OB)cosφ

AB² = 11,27,844 + 15,42,564 - 2 x 1242 x 1062 x cos(87.5°)

AB² = 11,27,844 + 15,42,564 - 2 x 1242 x 1062 x 0.044

AB² = 26,70,408 - 1,16,072.352 = 25,54,335.648

AB = √25,54,335.648

AB = 1598.22 meters

Hence, the distance between first airplane and second airplane after 1.8 hours of their departure is 1598.22 meters.

The mathematical relationship between heat, internal energy and work done by the system is given as:

△U = Q + W

where △U is the change in the internal energy

W is the workdone by the system

Q is the heat energy in the system

Since the workdone by the system is negative, when a system does work, there is a depletion in the amount of energy possessed by the system.

Due to this loss of energy by the system as a result of the workdone, the internal energy decreases.

The tendency of an object to resist a change in velocity is called inertia. It is the resistance of an object to a change in its direction or speed of motion.

This property of matter is explained by Newton's First Law of Motion, which states that an object at rest or in motion will remain in that state unless an external force acts on it.

Inertia is the basis for the concept of momentum, which is the product of an object's mass and velocity.

When an object is in motion, it has momentum and is resistant to any change in its velocity. This is because it has inertia, which is the tendency of an object to resist a change in motion.

Inertia is an important concept in physics and is essential for understanding the motion of objects in the universe.

The International Space Station (ISS) has both gravitational potential energy (PE) and kinetic energy (KE). PE is the energy an object possesses due to its position in a gravitational field, while KE is the energy an object possesses due to its motion. Both energies are essential for the ISS to maintain a stable orbit.

The International Space Station (ISS) orbits Earth at an altitude of approximately 408 kilometers. While it is true that the ISS is in a state of constant freefall, it still experiences gravitational force due to Earth's gravitational pull. This gravitational force allows the space station to remain in its orbit, otherwise, it would drift off into space. The ISS has both potential energy (PE) and kinetic energy (KE) due to its orbit around the Earth. PE refers to the energy an object possesses due to its position, while KE refers to the energy an object possesses due to its motion. In the case of the ISS, its potential energy is determined by its distance from Earth's surface, and its kinetic energy is determined by its velocity as it orbits the planet. Thus, the ISS has both gravitational potential energy and kinetic energy.

The dimensions of a is L⁵·M·T⁻²mol⁻²

Explanation:

The gas equation for a real gas, can be presented as follows;

\(\left (P + \dfrac{n^2 \cdot a}{V^2} \right) \cdot \left (V - n \cdot b\right) = R \cdot T\)

Where;

P = The pressure

V = The volume

a = A constant representing intermolecular forces

b = A constant representing molecular volume

n = The number of moles

The dimensions of the expression \(P + \dfrac{n^2 \cdot a}{V^2}\) is in units of pressure, given that 'P' is in units of pressure, bar, therefore, the expression, \(\dfrac{n^2 \cdot a}{V^2}\), is also measured in units of pressure

The dimensions of pressure, P = M·L⁻¹·T⁻²

'n²' unit dimension is mol², while V² is measured as liter² (L³), therefore, 'a' will convert the units of n² and V² to bars, therefore, we have;

The unit dimension of a = L²·bar/(mol²)

(L³)²·(M/(L·T²))/(mol²) = L⁵·M·T⁻²mol⁻²

The dimension of a = L⁵·M·T⁻²mol⁻²

Where;

L = Length in meters

T = Time in seconds

M = Mass in kilogram

The planetary body with the fastest orbit is Mercury, and the one with the slowest orbit is Neptune.

There is a general pattern between orbital velocity and orbital radius known as Kepler's second law of planetary motion. According to this law, a planet sweeps out equal areas in equal times as it orbits the Sun. This implies that planets closer to the Sun have smaller orbital radii and must travel faster to cover the same area in the same amount of time.

The relationship between orbital velocity and orbital radius can be expressed as v ∝ 1/r, where v represents the orbital velocity and r denotes the orbital radius. This relationship shows that as the orbital radius increases, the orbital velocity decreases. In other words, planets farther from the Sun have slower orbital velocities compared to those closer to the Sun.

This pattern is consistent with observations in our solar system. The inner planets, such as Mercury, have smaller orbital radii and faster orbital velocities, while the outer planets, like Neptune, have larger orbital radii and slower orbital velocities.

Explanation:

If a current is in a loop of wire and also in a magnetic field, the loop wants to rotate.

This phenomenon is known as the principle of operation of a DC motor. The current-carrying loop placed in a magnetic field experiences torque, and this torque will cause the loop to rotate.

A DC motor is a type of electric motor that converts electrical energy into mechanical energy. It works on the principle that a current-carrying conductor in a magnetic field experiences a force that causes it to rotate. It consists of a stator, which generates a magnetic field, and a rotor, which carries the current and rotates.

The commutator is a device that allows the current to flow in the correct direction through the rotor windings. As the rotor rotates, the brushes on the commutator change the direction of the current flow, allowing the rotor to continue to rotate.

The speed of the DC motor can be controlled by varying the applied voltage or the strength of the magnetic field. The direction of rotation can be reversed by reversing the polarity of the applied voltage or by changing the polarity of the magnetic field.

DC motors are used in a variety of applications, including electric vehicles, robotics, and industrial machinery.

In summary, when a current-carrying loop is placed in a magnetic field, it experiences a torque that causes it to rotate. This principle is the basis for the operation of a DC motor.

Compared with angle theta, the angle of refraction of the ray emerging from plate y into the air will be greater than the angle of incidence because the refractive index of the glass is greater than that of air.

When a light ray passes through a glass slab of given thickness, the deviation is primarily dependent on the angle of incidence (angle i), the angle of refraction (angle r), and the thickness of the glass slab t. The angle of refraction of the ray emerging from plate y into the air will be greater than the angle of incidence because the refractive index of the glass is greater than that of air.

When a light beam passes from a medium with a high refractive index to a medium with a low refractive index, it is refracted away from the normal. When light travels from air to glass, the speed decreases and the direction changes. Since the refractive index of air is lower than the refractive index of glass, the angle of refraction will be greater than the angle of incidence. Therefore, the angle of refraction will be greater than the angle of incidence as the light passes from glass to air.

The ball is in the air for about 1.8 seconds before it hits the ground after it leaves the student's hand with a speed of 11 m/s when the hand is 1.8 m above the ground.

Projectile motion is a kind of movement experienced by an object or particle (a projectile) that is projected near the Earth's surface and moves along a curved path under the gravity of the Earth. In general, projectile motion refers to a free-body's motion influenced only by gravity. A student throws a ball straight up while standing on the ground. When her hand is 1.8 m above the ground, the ball leaves her hand at a speed of 11 m/s. The time the ball is in the air before it hits the ground is calculated as follows:Using the equation:

∆y = v0yt + 1/2gt² Where ∆y is the displacement (in this case, -1.8 m) of the projectile along the vertical axis, v0y is the initial vertical velocity (in this case, 11 m/s), t is the time of flight, and g is the acceleration due to gravity (9.81 m/s²):-1.8 m = (11 m/s)t + (1/2)(-9.81 m/s²)t².Rearranging the equation, we get:-4.905t² + 11t - 1.8 = 0.

Using the quadratic formula, we get:t = (-11 ± sqrt(11² - 4(-4.905)(-1.8))) / (2(-4.905))= 1.77 s or t = 0.20 s. Since the ball is in the air for approximately 1.77 s before it hits the ground, and the student's hand is 1.8 m above the ground, the ball is in the air for about 1.8 seconds before it hits the ground. Therefore, the correct answer is the option C, 1.8 seconds.
