6 V drop occurs across the 6 ohm resistor in the parallel circuit diagram. The correct answer is C.

Since this parallel combination is connected with a cell, the potential difference through each resistor will be 6 volts. Now using I=V/R,

Current through 3 ohm resistor = 6/3 = 2 V

Current through 6 ohm resistor = 6/6 = 1 V

And the total current will be the sum of individual current in each resistor using Kirchoff’s junction law, Total current = 3 ampere

Since it is parallel combination the current passing across two resistors can differ but the voltage drop will remain the same.

Half the potential difference of the 1μf capacitor.

Charge: Q = CV where C is the capacitance in Farads, V is the voltage across the capacitor in Volts and Q is the charge measured in coulombs (C).

Energy stored: W = ½ QV = ½ CV×V

where W is the energy measured in Joules.

As the capacitance of a capacitor is equal to the ratio of the stored charge to the potential difference across its plates, giving: C = Q/V, thus V = Q/C as Q is constant across all series connected capacitors, therefore the individual voltage drops across each capacitor is determined by its its capacitance value.

When the capacitors are connected in the form of series combination, the capacitance in total is less than the individual capacitances of the series capacitors. If one, two or number of capacitors are connected in the series form, the overall effect is the single or equivalent capacitor which has the total sum of the spacings between the plates of the individual capacitors. The increase in the plate spacing results in the decreased capacitance, with all the other factors remaining unchanged.

Kinematics is a subfield of physics, developed in classical mechanics, that describes the motion of points, bodies (objects), and systems of bodies (groups of objects) without considering the forces that cause them to move.

Kinematics, as a field of study, is often referred to as the "geometry of motion" and is occasionally seen as a branch of mathematics. A kinematics problem begins by describing the geometry of the system and declaring the initial conditions of any known values of position, velocity and/or acceleration of points within the system.

The required probabilities are calculated by using the binomial distribution formula as below:

a. The probability that 5 will still be with the company after 1 year is P(x = 5) = 0.2541

b. The probability that 5 or more still be with the company after 1 year is 0.8057.

The binomial distribution formula for finding the required probability of a random variable is

[tex]P(X = r) = _nC_rp^rq^{n-r}[/tex]

Where

[tex]_nC_r = \frac{n!}{r!(n-r)!}[/tex]

p = probability of success

q = 1 - p = probability of failure

n = total number of trials

r = number of trials chosen

It is given that,

n = 8 and p = 0.7

Then, q = 1 - 0.7 = 0.3

a. The probability that 5 will still be with the company after 1 year:

P(X = 5) = [tex]_8C_5[/tex] (0.7)⁵(0.3)⁸⁻⁵

⇒ [tex]\frac{8!}{5!(8-5)!}[/tex] (0.7)⁵(0.3)³

⇒ 0.2541

Therefore, the probability P(x = 5) is 0.254.

b. The probability that 5 or more still be with the company after 1 year:

More than 5 means 6, 7, and 8

So,

P(X = 6) = [tex]_8C_6[/tex] (0.7)⁶(0.3)⁸⁻⁶

⇒ [tex]\frac{8!}{6!(8-6)!}[/tex] (0.7)⁶(0.3)²

⇒ 0.2964

P(X = 7) = [tex]_8C_7[/tex] (0.7)⁷(0.3)⁸⁻⁷

⇒ [tex]\frac{8!}{7!(8-7)!}[/tex] (0.7)⁷(0.3)¹

⇒ 0.1976

P(X = 8) = [tex]_8C_8[/tex] (0.7)⁸(0.3)⁸⁻⁸

⇒ [tex]\frac{8!}{8!(8-8)!}[/tex] (0.7)⁸(0.3)⁰

⇒ 0.0576

Thus, the probability that 5 or more still be with the company after 1 year

= P(5) + P(6) + P(7) + P(8)

= 0.2541 + 0.2964 + 0.1976 + 0.0576

When a beam of light  that is, at first, in air and oriented perpendicular to the surface of a body of water be deflected as a result of transition into water--------It does not deflect , the light direction will not change.

What happens to light when it passes through air?

All materials have what is known as an index of refraction, which is linked to how fast light can travel through the material. As light passes through air and into another clear material (such as glass), it changes speed, and light is both reflected and refracted by the glass.

How does light travel through air and water?

When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction. When light enters a more dense substance (higher refractive index), it 'bends' more towards the normal line.

Algol variables, also known as Algol-type binaries, are a subclass of eclipsing binary stars that resemble Persei, the class's prototype star (Beta Persei, Algol). An Algol binary is a system in which both stars are almost spherical, making it possible to precisely predict when the eclipses would begin and conclude. Usually, the primary is a main-sequence star that is located close to its Roche lobe. The secondary star might be either an evolved star occupying its Roche lobe, known as a semidetached binary, or it could be a main sequence star, known as a detached binary.
