When an atom undergoes radioactive decay, its nucleus releases a beta particle.

Because of thin-film interference, which occurs when light waves reflecting off a film’s top surface interfere with waves reflecting off its bottom surface, a thin oil film on a water surface appears colored. Option B is therefore accurate.

B = µ0 I / 2 π r

= 4 π x 10-7 x 25 / 2 π (3 x 10-2)

= 1.666666 x 10-4

1.67 x 10-4

Since the field is created between the two charges—from the +ve charge to the -ve charge—no electric field can exist on X or Z, and the field lines will only cross at Y.

Let g be the Earth’s free fall acceleration.
Free fall acceleration on the moon = g16
At a height of two meters, the stone is released from its rest.

starting speed, u = 0. Distance, s = 2 m
The uniformly accelerated motion equation is s = ut + ½ at2.
The time required on Earth is t 2=0+0.5g12 Acceleration, g=4/12
Think about the stone hitting the moon now. Let tM. 2=0+0.5 (g/6) tM2 be the amount of time required.
Time tM is equal to √(4/9)=√(24/4/12)) = ✓(6/12)=⅙
There is only one possible response because it is a numerical question.

The equivalent resistance of a circuit decreases and the circuit’s total current increases as more and more resistors are connected in parallel. More branches for the flow of charge are created by connecting more resistors in parallel.

½ + ⅙ + ¼ = 12/11.

On the high side, human resistance is roughly 10,000 ohms; if the person is wet, it can be as low as 1,000 ohms.

The resistance of the human body varies; it is 100,000 ohms when it is dry.

Skin thickness, exposed sub-epidermal tissue, and internal and external moisture all affect how resistant the human body is to current flow. Consequently, the value might change, so option C—”120K ohms”—is the estimated response.

The distance between an object’s starting and ending positions on a straight line is known as the displacement’s magnitude. It concentrates on finding the shortest distance between two places rather than taking into account the object’s actual route.

A car requires centripetal force to maintain its trajectory when turning on a horizontal road. The force that keeps an object moving in a circle is called centripetal force, and it is directed toward the center of the circular path. The friction between the tires and the road provides this force when an automobile turns.

Due to inertia, which keeps objects moving in a straight line, the car may slide outward if there is insufficient centripetal force. This lack of centripetal force may be caused by the vehicle traveling too quickly for the turn or by slick roads that lessen tire-to-road friction.

The necessary formula is as follows: stopping voltage = Kmax/e, where Kmax/e = 5.0eV/e.

Kmax/e = 5.0 V
Consequently, 5 V is the stopping potential.

The laws of physics, particularly the principle of inertia, apply to the mud on a bicycle tire when it is in motion. According to the law of inertia, unless an outside force acts upon an object, it will continue to move in the same direction or remain at rest.

Because of its inertia, the mud on the bicycle tire wants to keep going in the same direction as the tire moves forward. Nevertheless, the tire limits it. Because the tire is rolling, the point of contact between it and the ground is momentarily at rest (in relation to the tire). As a result, when the tire leaves the ground, the mud is thrown off in a direction tangent to the tire.

Motional emf = Bℓv (perpendicular to B,ℓ, and v)

Emf = 0.01 = 1 * 10-2 V = (0.20T) * (0.1m) * (0.5m/s)

Since the distance between distinct fringes varies with wavelength, increasing the light’s wavelength also increases the distance between them. Violet light has the smallest wavelength in the color spectrum, ranging from 380 to 435 nm, while red light has the largest, ranging from 625 to 740 nm.

The pattern of interference shifts. There are fewer constructive and destructive interference points as the wavelength increases. The quiet and noisy areas are farther apart. Similarly, there are more areas of interference when the tone is changed to a lower wavelength.

An antiquark is a type of antiparticle that corresponds to each quark and differs from it only in certain aspects (e.g., electric charge). Their signs are opposite, but their magnitudes are equal.
Antiproton is the proton’s antiparticle.
The positron is the electron’s antiparticle.
Antineutron is the neutron’s antiparticle.
