When identical resistors are connected to separate 12 V AC sources, one operating at 60 Hz and the other at 120 Hz, the behavior of the resistors will vary due to the difference in frequency.

The frequency of an AC source determines the number of cycles it completes per second. So, the 60 Hz source completes 60 cycles per second, while the 120 Hz source completes 120 cycles per second.

Since the resistors are identical, they have the same resistance value. When connected to the 60 Hz source, the resistor will experience a certain amount of current flow. This current flow is determined by the voltage and resistance according to Ohm's Law (V = IR).

Now, when the identical resistor is connected to the 120 Hz source, it will experience twice the number of cycles per second. This means that the current will fluctuate at a faster rate. As a result, the average current through the resistor will be higher compared to when it is connected to the 60 Hz source.

The phenomenon of the spotlights appearing brighter at the stage supports the wave model of light through the concept of constructive interference. When the light waves from both spotlights overlap and their peaks and troughs align, they combine to form a brighter light. This constructive interference demonstrates how light behaves as a wave and reinforces the wave model of light.

When two spotlights point toward a stage, it is common to observe that the spot where the two beams of light overlap appears to be brighter than the surrounding areas. This phenomenon can be explained by the wave model of light.
According to the wave model, light travels in the form of electromagnetic waves, which are characterized by their wavelength and frequency. When two waves of light overlap, they interfere with each other, either constructively or destructively, depending on the phase difference between the waves. If the waves are in phase, meaning that their peaks and troughs line up, they will add up to create a brighter spot where they overlap. This is known as constructive interference. On the other hand, if the waves are out of phase, meaning that their peaks and troughs do not line up, they will cancel each other out and create a darker spot where they overlap. This is known as destructive interference.

The waves of light emitted by each spotlight interfere with each other. At the point where the two beams overlap, the waves are in phase and therefore add up constructively, creating a brighter spot. This supports the wave model of light because it demonstrates how the interaction between waves of light can produce observable effects such as interference.

We can use the properties of parallel lines and transversals to determine the measures of the angles.

From the given information, we know that lines e and f are parallel, and the angles 9 and 80° form a linear pair, which means that angle 9 measures 180° - 80° = 100°.

Similarly, angle 5 and 55° form a linear pair, so angle 5 measures 180° - 55° = 125°.

Using the alternate interior angles property, we know that angles 3 and 8 are congruent, and both are equal to angle 5 - angle 4 = 125° - 80° = 45°. Therefore, option (ii) is incorrect.

Using the corresponding angles property, we know that angles 12 and 6 are congruent, and both are equal to angle 9 + angle 80° = 100° + 80° = 180°. Therefore, option (iv) is correct.

Using the vertical angles property, we know that angles 14 and 2 are congruent, and both are equal to angle 80°. Therefore, option (v) is correct.

Therefore, the correct options are (i) mangle2 = 125°, (iv) mangle12 = 100°, and (v) mangle14 = 100°.

Like a gas, plasma lacks a fixed volume and shape. Unlike a gas, plasma can conduct electricity and respond to magnetism. That's because plasma contains charged particles called ions. The particles that make up matter are also constantly moving.

The properties of both a gas and a plasma are:

A gas lacks both a fixed volume and a fixed shape. While certain gases are palpable to humans and can be seen and felt, others are not. The gases oxygen, helium, and air are a few examples. N2, O2, and CO2 are among the gases that make up the Earth's atmosphere.

Both the volume and shape of plasma are illusive. Ionized gases frequently contain plasma, yet plasma differs from a gas in that it has special characteristics. The plasma is electrically conductive because it contains free electrical charges that aren't attached to atoms or ions. A gas can be heated and ionized to create plasma.

One crucial maintenance component of a refrigeration system is the purge unit.Purge units are designed to remove noncondensables from a refrigeration system. When air enters a refrigeration system, it becomes trapped and accumulates, reducing the efficiency of the system and increasing the likelihood of breakdowns.

To avoid this, purge units work to remove the air and other noncondensable gases from the system through an air eliminator. The purge unit automatically releases the air and other noncondensable gases as they accumulate, keeping the refrigeration system running smoothly and efficiently.

Aside from purging the refrigeration system of noncondensables, some purge units can also be used to detect leaks in the system. If the purge unit is calibrated properly, it can identify the specific gas that is being released and alert the maintenance team to any potential leaks in the system. In addition, some purge units also have the ability to capture and reuse the refrigerant that is released, making them more environmentally friendly.

In summary, purge units are essential components of refrigeration systems that work to remove noncondensable gases from the system to ensure it runs at peak performance.

These units not only help to keep the system operating smoothly but also have the added benefit of detecting any potential leaks in the system.

The boat sinks by about 9.07 cm when the fishermen and their gear are aboard.

What is Mass?

Mass is a fundamental property of matter that measures the amount of matter in an object. It is a scalar quantity and is typically measured in units of kilograms (kg) or grams (g). Mass is different from weight, which is the force exerted on an object by gravity and varies depending on the strength of the gravitational field.

First, we need to find the volume of water displaced by the boat. Since the boat has a flat bottom, we can assume that it displaces a volume of water equal to its submerged depth multiplied by its bottom area. Let's assume that the boat sinks by a depth of h meters when the fishermen and their gear are aboard. Then:

Volume of water displaced = 4.0 m^2 × h

The weight of the water displaced is equal to the weight of the boat and everything in it, which is:

Weight of boat and gear = (60 + 300) kg × 9.81 m/\(s^{2}\)= 3528.6 N

The buoyant force is then:

Buoyant force = Weight of water displaced = Volume of water displaced × density of water × g

where g is the acceleration due to gravity. We can set this equal to the weight of the boat and gear:

4.0 \(m^{2}\) × h × 1000 kg/\(m^{3}\) × 9.81 m/\(s^{2}\) = 3528.6 N

Solving for h, we get:

h = 0.0907 m

Gravity influenced the formation of the solar system, with the planets orbiting the sun.

Gravitational force is force of attraction between two masses. Gravitational force(F) between two bodies is directly proportion to the product of masses(m₁,m₂) of two bodies and inversely proportional to square of distance(r) between them. mathematically it is written as,

F \(\alpha\) m₁.m₂

F \(\alpha\) 1/r²

F = G m₁,m₂÷r²

where G is gravitational constant, whose value is 6.6743 × 10⁻¹¹ m³ kg-1s⁻².
