The lines of iron fillings will be attracted towards the poles of the magnet on the paper. The fillings gets sticked on the magnet. The glass or plastic will stop the passage of the magnetic lines of force .

Magnetic field lines are lines of force generated by a strong magnetic field. For a bar magnet, the magnetic south pole and north pole are having stronger magnetic fields than the middle part.

When magnetically susceptible materials comes in contact with a magnet they gets attracted to the poles of the magnet. The fields lines of the material gets aligned parallel to the applied field.

Some materials such as paper and glass are not showing magnetic properties. Hence, they can stop the passage of magnetic field lines. If we place a glass or paper in between the poles of a two magnets, they will stick to the glass from both ends due to the attraction to the opposite pole.

The largest voltage the battery can have without breaking the circuit at the supports is 626.71 V.

The magnetic field on a current-carrying conductor is determined by the flow of current through the conductor and the distance from the carrier.

Voltage is the pressure exerted by an electrical circuit’s power source through a conducting loop to push charged electrons (“current”) through an electrical circuit to perform a function, such as turning on a light.

Given,

The length of the metal bar = 54.0 cm or 0.54 m

mass of the bar = 740 g or 0.74 kg

magnetic field acting perpendicular to the bar = 0.450 T

resistance  = 26.0

Let the maximum potential in the battery be V and the current in the circuit be I. So

V= IR

V = 26×I

I = V/21

For the rod to be in its position the magnetic force on the rod must be equal to the weight. So

magnetic force = weight

B×I×L = mg

0.45 × V/21 × 0.54 m =  0.74 × 9.8

V = 626.71 V

Thus the largest voltage the battery can have without breaking the circuit at the supports is 626.71 V.

Explanation:

a)The aperture size of the radio telescope needs to be approximately 0.27 meters b)The aperture of a radio telescope needs to be much larger than that of an optical telescope because radio waves have much longer wavelengths compared to visible light. c)the resolving power of a telescope depends on the ratio of the wavelength of light.

a. To determine the aperture size of a radio telescope to achieve a resolution at 21 cm, we can use the Rayleigh criterion, which states that the minimum resolvable separation (δθ) is given by:

δθ = 1.22 * (λ / D)

Where λ is the wavelength of the radiation and D is the diameter of the telescope's aperture.

Given that the radio wavelength is 21 cm (or 0.21 m), and we want to achieve the same resolution as the optical telescope (1 second of arc), we can rearrange the formula to solve for D:

D = 1.22 * (λ / δθ)

D = 1.22 * (0.21 m / 1 second of arc)

Calculating the result:

D ≈ 0.27 m

Therefore, the aperture size of the radio telescope needs to be approximately 0.27 meters to achieve a resolution of 1 second of arc at a wavelength of 21 cm.

b. The Rayleigh criterion tells us that the resolution of an instrument is inversely proportional to the wavelength.

Since radio waves have longer wavelengths, the telescope's aperture needs to be larger to achieve the same resolution as an optical telescope. This is because a larger aperture collects more incoming waves and allows for finer spatial detail to be resolved.

c. The ability to resolve two objects using a telescope depends on the size of the aperture relative to the wavelength of the radiation. When it comes to resolving stars, the resolving power of a telescope depends on the ratio of the wavelength of light to the size of the telescope's aperture (λ/D).

Blue light has a shorter wavelength compared to red light. Since the resolving power is directly proportional to the wavelength, a shorter wavelength of blue light allows for better resolution.

Therefore, two predominantly blue stars can be resolved because their shorter wavelength allows for finer detail to be distinguished, while the same separation between two predominantly red stars cannot be resolved due to the longer wavelength.

The velocity of the car when it began coasting was approximately 17.2 m/s.

If a car is coasting without any external force acting on it (such as friction), then its initial kinetic energy is converted entirely into potential energy as it moves uphill. Therefore, we can use the principle of conservation of energy to solve this problem.

The principle of conservation of energy states that the total energy of a closed system (in this case, the car and the Earth) remains constant over time. Therefore, the initial kinetic energy of the car is equal to the potential energy gained as it moves uphill. Mathematically, we can express this as:

1/2 mv^2 = mgh

where:

m = mass of the car

v = initial velocity of the car when it began coasting

g = acceleration due to gravity (9.8 m/s^2)

h = height gained by the car (15 m)

We can simplify this equation by canceling out the mass (m) on both sides:

1/2 v^2 = gh

Substituting the given values, we get:

1/2 v^2 = 9.8 m/s^2 * 15 m

v^2 = 2 * 9.8 m/s^2 * 15 m

v = √(2 * 9.8 m/s^2 * 15 m)

v ≈ 17.2 m/s

Explanation:

wavelength is denoted by the letter lambda it is equal to the speed (v) of a wave in a medium (air , water, light) divided by frequency , equals wavelength . so wavelength = v/f or = 23m/s ÷13hz

When the speed of a motor vehicle doubles, the amount of kinetic energy increases by a factor of four. This relationship is based on the kinetic energy formula:

Kinetic Energy (KE) = 0.5 * mass * velocity^2

According to this formula, kinetic energy is directly proportional to the square of the velocity. Doubling the speed of the vehicle means doubling the velocity value in the formula. Let's examine the impact of this change on the kinetic energy.

If we denote the initial velocity as V1 and the final velocity as V2 (where V2 = 2 * V1), we can calculate the ratio of the kinetic energies:

KE2 / KE1 = (0.5 * mass * V2^2) / (0.5 * mass * V1^2)

Simplifying the equation and substituting V2 = 2 * V1:

KE2 / KE1 = (0.5 * mass * (2 * V1)^2) / (0.5 * mass * V1^2)

KE2 / KE1 = (0.5 * mass * 4 * V1^2) / (0.5 * mass * V1^2)

KE2 / KE1 = 4

Therefore, when the speed of a motor vehicle doubles, the amount of kinetic energy increases by a factor of four. This demonstrates the significant impact that speed has on the kinetic energy of a moving object.

A tuning fork is struck, vibrating the fork and generating sound. When the tuning fork is submerged in water, the sound waves are dampened, and the sound is reduced.

Sound waves are made up of vibrations, and vibrations need a medium to travel through. The density of the medium affects the velocity of sound in it. As a result, sound waves move more slowly in water than they do in air. However, when a tuning fork is submerged in water, the sound waves that it generates travel through the water, which is a more dense medium than air.

As a result, the sound waves are refracted, or bent, and lose their energy faster, causing the sound to fade more quickly.If a tuning fork is struck while submerged in water, it will create sound waves in the water. Sound waves produced in water have less energy and travel slower than sound waves generated in air.

The potential difference between the plates is 3,281.25 V, with plate A at the higher potential.

The kinetic energy of an electron is given as 5.25 × \(10^{-16}\) J. This kinetic energy gained by the electron is equal to the work done on the electron by the electric field. Using the formula for the kinetic energy of an electron in an electric field we get, KE = (1/2)mv², where KE is the kinetic energy, m is the mass of the electron and v is the velocity of the electron.

In this case, we are given the value of KE which is 5.25 × \(10^{-16}\) J. We know the mass of the electron is 9.1 × \(10^{-31}\) kg.  Therefore, we can calculate the velocity of the electron using the given kinetic energy.

= 5.25 × \(10^{-16}\) = (1/2) × (9.1 × \(10^{-31}\)) × v²

⇒ v = 1.25 X × \(10^{7}\) m/s

The potential difference between the plates is given by the formula,

V = (KE / e)

where V is the potential difference, KE is the kinetic energy of the electron, and e is the charge on the electron which is equal to 1.6 × \(10^{-19}\) C. Therefore,

V = (5.25 × \(10^{-16}\) / 1.6 × \(10^{-19}\))
