A balloon expands as you blow into it because of the increase in pressure inside the balloon caused by the air you are blowing into it. When you blow air into a balloon, the air molecules inside the balloon are pushed closer together, increasing the pressure inside the balloon. As the pressure inside the balloon increases, the balloon stretches and expands to accommodate the extra air.

The balloon is made of a flexible material, such as rubber or latex, which allows it to stretch and expand as the pressure inside it increases. The balloon's material has elastic properties, which means that it returns to its original shape when the pressure is released.

The process of blowing air into a balloon can be compared to filling a tire with air. As you inflate a tire with a pump, the air molecules inside the tire are pushed closer together, increasing the pressure inside the tire. This causes the tire to expand and become larger, until it reaches the desired pressure.

In summary, a balloon expands as you blow into it because of the increase in pressure inside the balloon caused by the air you are blowing into it. The balloon's material has elastic properties, which allows it to stretch and expand as the pressure inside it increases.

The moment of inertia of the cylinder about the horizontal axis parallel and tangent to the cylinder is 3MR²/2.

The moment of inertia (Icm) of the cylinder about its symmetrical axis is calculated using the formula MR^2/2, where M represents the mass of the cylinder and R represents its radius.

To find the moment of inertia of the cylinder about the axis parallel and tangent to the cylinder, we can use the parallel axis theorem. According to the parallel axis theorem, the moment of inertia about an axis parallel to and at a distance 'd' from the axis passing through the center of mass is given by:

I = Icm + Md^2

In this case, the axis of rotation is parallel and tangent to the cylinder, so the distance 'd' from the axis passing through the center of mass is equal to the radius 'R'. Substituting the values into the equation:

I = Icm + MR^2

I = MR^2/2 + MR^2

I = (1/2 + 1)MR^2

I = (3/2)MR^2

Therefore, the moment of inertia of the cylinder about the given axis is (3/2)MR^2.

The correct answer is (D) 3MR^2/2.

In a single atom, the maximum number of electrons that can have the quantum number n = 4 is 32 electrons.

In a single atom, the maximum number of electrons that can have the quantum number n = 4 is determined by the available subshells within the principal energy level (n). Quantum numbers help describe the specific location and energy of electrons in an atom.

The principal quantum number (n) indicates the main energy level of the electron, and when n = 4, there are four subshells available: s, p, d, and f. Each subshell can hold a certain number of electrons based on their angular momentum quantum number (l), with s holding 2, p holding 6, d holding 10, and f holding 14 electrons.

To calculate the maximum number of electrons in the n = 4 energy level, add the maximum number of electrons from each subshell:

2 (from s) + 6 (from p) + 10 (from d) + 14 (from f) = 32 electrons

Therefore, in a single atom, the maximum number of electrons that can have the quantum number n = 4 is 32 electrons.

The activity of the sample after 5 hours is 2.5 * 10^9 dps or 2.5 * 10^9 Bq

The activity of a radioactive sample refers to the rate at which its nuclei decay, and it is typically measured in units of disintegrations per second (dps) or becquerels (Bq).

To determine the activity of the sample after 5 hours, we need to consider the concept of half-life. The half-life of a radioactive substance is the time it takes for half of the nuclei in a sample to decay.

Given that the half-life of the nuclei in the sample is 2.5 hours, we can calculate the number of half-lives that occur within the 5-hour period.

Number of half-lives = (Time elapsed) / (Half-life)

Number of half-lives = 5 hours / 2.5 hours = 2

This means that within the 5-hour period, two half-lives have occurred.

Since each half-life reduces the number of nuclei by half, after one half-life, the number of nuclei remaining is (1/2) * (10^10) = 5 * 10^9 nuclei.

After two half-lives, the number of nuclei remaining is (1/2) * (5 * 10^9) = 2.5 * 10^9 nuclei.

The activity of the sample is directly proportional to the number of remaining nuclei.

Therefore, After 5 hours, the sample has an activity of 2.5 * 109 dps or 2.5 * 109 Bq.

The width of the 20 m long conductor should be approximately 0.05 meters.

To determine the width of the conductor, we first need to find its cross-sectional area (A) using the given uniform current density (J) and current (I). The formula for this is:

A = I / J

Plugging in the given values:

A = 1.0 A / 400 A/m² = 0.0025 m²

Since the conductor has a square cross-section, its width (w) will be the square root of the cross-sectional area:

w = √A = √0.0025 m² ≈ 0.05 m

So, the width of the 20 m long conductor should be approximately 0.05 meters.

The use of prefixes makes expressing and converting measurements easier by providing a consistent way to describe quantities and their units. For example, the prefix "kilo-" means 1000, so one kilometer is equal to 1000 meters.

Proper use of prefixes in measurements is essential for converting units from one system to another, or even within the same system. It can help avoid errors and confusion and simplify calculations.

The use of prefixes makes expressing and converting measurements easier by providing a consistent way to describe quantities and their units. A prefix is a group of letters placed before a unit symbol to change its value by a factor of 10.

For example, the prefix "kilo-" means 1000, so one kilometer is equal to 1000 meters. The prefix "centi-" means one-hundredth, so one centimeter is equal to one-hundredth of a meter. The prefix "milli-" means one-thousandth, so one milliliter is equal to one-thousandth of a liter.

Using prefixes can also simplify calculations involving measurements. For instance, if we need to convert 1000 millimeters to meters, we can divide by 1000 since milli- means one-thousandth, resulting in 1 meter. Similarly, if we need to convert 2 kilometers to centimeters, we can multiply by 100,000 since kilo- means 1000, resulting in 200,000 centimeters.

Furthermore, prefixes are also used in scientific notation to express very large or very small numbers. For instance, the speed of light is approximately \(3 * 10^8\) meters per second, which can be written as 300,000,000 m/s.

In conclusion, using prefixes in measurements can make it easier to express, convert, and understand quantities and their units. They provide a consistent way to change the value of a unit by a factor of 10 and are essential in scientific calculations and measurements.

According to the question the potential drop across the resistor is 3.00 volts.

A resistor is an electrical component that is used to impede or restrict the flow of electric current in a circuit. It is designed to have a specific resistance value, which is measured in ohms (Ω).

Resistors are typically made of materials such as carbon, metal film, or wirewound elements, which offer a certain level of electrical resistance.

The potential drop across the resistor can be calculated using Ohm's Law, which states that the potential difference (V) across a resistor is equal to the current (I) multiplied by the resistance (R).

In this case, the current is 1.50A and the resistance is 2.00Ω. Therefore, the potential drop across the resistor can be calculated as:

V = I * R

V = 1.50A * 2.00Ω

V = 3.00V

Therefore, the potential drop across the resistor is 3.00 volts.

Suppose you walk across a carpet with socks on your feet. When you touch a metal door handle, you feel a shock because, c. Excess negative charges build up in your body while walking across the carpet, then jump when attracted to the positive charges in the door handle.

When you walk across a carpet with socks on your feet, the friction between the carpet and your socks causes the transfer of electrons. Electrons are negatively charged particles. As you move, the carpet rubs against your socks, stripping some electrons from the atoms in the carpet and transferring them to your socks. This results in your body gaining an excess of negative charges.

The metal door handle, on the other hand, contains positive charges. When you touch the metal door handle, there is a sudden flow of electrons from your body to the door handle. This movement of electrons is known as an electric discharge or a static shock. The excess negative charges in your body are attracted to the positive charges in the door handle, and this attraction causes the sudden discharge of electrons, resulting in the shock that you feel.

It's important to note that the shock occurs due to the difference in charges between your body and the metal door handle. The friction between your socks and the carpet allows for the buildup of static electricity, and the shock is a result of the equalization of charges when you touch the metal object.

Systolic pressure is the arterial blood pressure attained during the contraction phase of the cardiac cycle.

The cardiac cycle refers to the sequence of events that occur during one complete heartbeat. It consists of two main phases: diastole and systole. Diastole is the relaxation phase when the heart chambers fill with blood, while systole is the contraction phase when the heart pumps blood out into the arteries.

During systole, the ventricles of the heart contract, generating pressure to push blood into the aorta and the rest of the arterial system. This forceful contraction causes the highest pressure in the arteries, known as systolic pressure. It represents the peak arterial blood pressure that occurs when the heart is actively pumping blood.

Systolic pressure is typically measured as part of blood pressure readings, represented by the higher number in the measurement. For example, if a person's blood pressure is recorded as 120/80 mmHg, "120" refers to the systolic pressure, while "80" represents the diastolic pressure.

The systolic pressure is an important indicator of cardiovascular health and is influenced by various factors, including the strength of the heart's contraction, the volume of blood being pumped, and the overall elasticity of the arterial walls. Monitoring systolic pressure helps in assessing cardiac function and diagnosing conditions such as hypertension (high blood pressure) or hypotension (low blood pressure).
