Blackbody radiation is a phenomenon that exhibit particle nature of light. Correct option is (B).

(a) Interference is a phenomenon in which two waves of same frequency superpose to give resultant intensity different from sum of their separate intensity. So, it cannot exhibit particle's nature of light.

(b) Blackbody radiation is a theoretical concept in quantum mechanics in which a material or substance completely absorbs all frequencies of light. It exhibit particle nature of light.

(c) Diffraction is a phenomenon in which light bends at sharp ends of an obstacle or a hole. So, it also cannot exhibit particle's nature of light.

Answer:

As battery is rated for 1.6 Ah, it delivers maximum current of 1.6 Ah / 14 hours = 0.114 A over 14 hours. Assume battery is fully charged.

An ampere-hour, or Ah, is a measure of the charge stored in a battery and can be used to calculate the maximum current that can be drawn from the battery over a certain time period.

The amount of current that can be delivered over 14 hours by a 1.6 Ah battery can be calculated by dividing the battery's capacity by the time period:

I = Q / t

where I is the current, Q is the charge stored in the battery (1.6 Ah), and t is the time period (14 hours).

Since the battery is rated for 1.6 Ah, it can deliver a maximum current of 1.6 Ah / 14 hours = 0.114 A over 14 hours. This assumes that the battery is fully charged and that no other losses, such as internal resistance or self-discharge, are taken into account.

It's important to note that the actual current that can be delivered may be lower than the calculated value, especially as the battery discharges. The actual current will depend on various factors, including the battery's internal resistance, the voltage drop across its terminals, and the load applied to the battery.

1. The power output in watts of an incandescent light bulb can be calculated by dividing the energy output (in joules) by the time interval (in seconds) during which the energy is produced.

In this case, the light bulb is producing 100 J of energy every 1 second, so the power output can be calculated as:

Power output (P) = Energy output (E) / Time interval (t) = 100 J / 1 second = 100 Watts

2. A 100-watt light bulb looks brighter than a 60-watt light bulb because it produces more energy and therefore emits more light. The brightness of a light bulb is directly proportional to the energy it produces.

A 100-watt light bulb produces more energy (and therefore light) than a 60-watt light bulb, so it appears brighter.

However, it is important to note that the perceived brightness of a light bulb can also be affected by other factors such as the color temperature of the light, the size of the bulb, and the reflectiveness of the surrounding area.

Explanation:

The turns ratio between the primary and secondary of a transformer can be calculated as follows:

Turns ratio = Secondary voltage / Primary voltage

So, in this case:

Turns ratio = 120V / 240V = 1/2

Since the turns ratio is the ratio of the number of turns in the secondary to the number of turns in the primary, the number of turns in the secondary can be found by:

Secondary turns = Primary turns / Turns ratio

In this case, with a primary of 5,500 turns:

Secondary turns = 5,500 turns / (1/2) = 11,000 turns.

So the secondary has 11,000 turns.

Spending years working on a construction site can have a negative effect on a person's hearing. This is because construction sites are often loud environments, with the constant sound of heavy machinery and power tools. Over time, exposure to these loud noises can damage the delicate hairs in the inner ear that transmit sound to the brain. This damage can cause hearing loss, which may be temporary or permanent depending on the severity and duration of exposure. Additionally, the use of earplugs or other hearing protection devices may not always be possible, especially if workers need to communicate with each other or are unable to hear warning signals. This makes it even more important for workers to take steps to protect their hearing, such as wearing ear protection when possible and limiting exposure to loud noises.

Newton's second law of motion provides the definition of the force formula. You must use SI units in order to apply this formula. Calculate the force in Newtons, the mass in kilograms, and the acceleration in square meters per second. This is what the formula means: Mass (kg) times acceleration (m/s2) equals force (N). When a force is applied, an object with constant mass accelerates in proportion.

3 kg of mass is given.

The difference between the applied force and the friction force, which is 12.8 - 5.2 = 7.6 N, determines the net force. Acceleration is calculated as Force/Mass, which is 7.6 / 3 = 2.533 m/s2.

When the angular momentum quantum number (ell) is zero and the primary quantum number (n) is two, the only feasible value for m cell is zero.

The orbital's size is defined by the main quantum number (n). For example, bigger orbitals are possible for n = 2 than for n = 1. Electrons are drawn to the atomic nucleus of an atom because of their opposing electrical charges. Consequently, energy must be absorbed to excite an electron from an orbital where it is close to the nucleus (n = 1) into an orbital where it is distant from the nucleus (n = 2). A orbital's energy is therefore indirectly described by the primary quantum number.

The final charge on the first capacitor is 7.20 μC and the final charge on the second capacitor is 12.00 μC.

When placed in an electromagnetic field, the physical property of matter known as electric charge causes it to experience a force.

Positive and negative electric charges are the two types of charges that charge carriers, protons and electrons, commonly carry. The movement of charges produces energy.

The initial charge on the first capacitor, 1, can be calculated using the formula as follows:

Q = C × V

where,

Q is the charge,

C is the capacitance, and

V is the voltage.

By substituting the values, we get:

Q = 2.40 μF × 8.00 V

= 19.2 μC

Let's call the final charge on the first capacitor 1,f and the final charge on the second capacitor 2,f.

So, the two capacitors are now connected in parallel, their equivalent capacitance is C_eq :

C_eq = C1 + C2

C_eq = 2.40 μF + 5.60 μF

= 8.00 μF

The final charge on the equivalent capacitance is equal to the initial charge on the first capacitor,

Q_eq = Q1,f = 19.2 μC

From this, we can calculate the final charge on each capacitor:

Q1,f = (C1 / C_eq) × Q_eq

Q1,f = (2.40 μF / 8.00 μF) × 19.2 μC

= 7.20 μC

Q2,f = (C2 / C_eq) × Q_eq

Q2,f = (5.60 μF / 8.00 μF) × 19.2 μC

= 12.00 μC

Thus, The final charge on the first capacitor is 7.20 μC and the final charge on the second capacitor is 12.00 μC.
