The inverse square relation implies that  force resulting from gravity between two masses will decrease as the square of the distance between the two masses increases.

The force of gravity between any two objects is given by,

F = GM₁M₂/R²

Where,

M₁ and M₂ are the masses of the bodies.

R is the distance between them.

We know, if the masses are constant. then the force of gravity will be inversely proportional to the square of the distance between them.

This is what inverse square relation means here.

As the force of gravity and the square of the distance are inversely proportional to each other,

So, when the square of the distance between the masses increases, the force of gravity between the decreases.

Hence of all the options provided, b is the correc0,t which says, the force will decrease on increasing the inverse square of the distance.

Since we need to assemble 30 units of p, the total amount of component k required would be (x/2) * 30 units.

To determine the quantity of component k that will be needed to assemble 30 units of p, we need to have the required amount of component k for one unit of p.

The required amount of component k can be obtained from the given data.

A component k is required in a ratio of 2:1 with component j to produce one unit of p. This means that for every two units of component j, one unit of component k is required.

So, to find the required quantity of component k for one unit of p, we need to divide the amount of component k required for 2 units of component j by 2.

Let's assume that x units of component j are required for one unit of p. Then, the required amount of component k for one unit of p would be x/2 units.

Since component j is required in a ratio of 3:1 with component i, we can assume that y units of component i are required for one unit of p.

Then, the required amount of component j for one unit of p would be 3y units.

Therefore, the total amount of component k required for one unit of p can be expressed as (x/2) units. The total amount of component j required for one unit of p can be expressed as 3y units.

Explanation:

1.Solid to Liquid --When a solid is heated the particles gain energy and start to vibrate faster and faster. ... Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid. The particles in the liquid are the same as in the solid but they have more energy.

2.Liquid to Gas--Vaporization occurs when a substance changes from a liquid to a gas. The molecules in a liquid are in constant motion while staying relatively close together due to intermolecular forces. When an increase in temperature occurs, the molecules' kinetic energy also increases.

The tractor-trailer truck would be more difficult to stop than a Fiat 500 traveling at the same speed due to its greater mass.

The difficulty in stopping a moving object is determined by the amount of force required to bring it to a complete halt. According to the formula "force = mass x acceleration," the greater the mass of an object, the more force is needed to stop it.

In the case of the tractor-trailer truck and the Fiat 500 traveling at the same speed of 35 meters per second, the tractor-trailer has a much larger mass than the Fiat 500. Therefore, it would require more force to bring the tractor-trailer to a complete stop.

The mass of a tractor-trailer truck can range from 30,000 to 80,000 pounds, whereas a Fiat 500 weighs around 2,500 pounds. This means that the force required to stop the tractor-trailer truck would be significantly greater than that required to stop the Fiat 500. The truck's momentum is much higher due to its mass, which makes it more difficult to change its direction or bring it to a complete stop.

n terms of the Beer-Lambert law, which states that the intensity of light (I) is proportional to the amount of light-absorbing material (A) and the distance it travels through the material (d), according to the equation:

I = I0 e^(-αd)

where I0 is the initial intensity of the light, α is the absorption coefficient of the material, and e is the base of the natural logarithm.

In pulse oximetry, a device called a pulse oximeter is placed on a patient's finger or earlobe. The pulse oximeter emits light of two different wavelengths (typically red and infrared) into the tissue, and then measures the amount of light that is transmitted through the tissue and reaches a detector on the other side.

The amount of light absorbed by the tissue depends on the concentration of oxygenated and deoxygenated hemoglobin in the blood. Oxygenated hemoglobin absorbs less light at the red wavelength and more light at the infrared wavelength, while deoxygenated hemoglobin absorbs more light at the red wavelength and less light at the infrared wavelength.

By measuring the difference in absorption between the two wavelengths, the pulse oximeter can calculate the oxygen saturation of the blood, which is the percentage of hemoglobin in the blood that is carrying oxygen.

The pulse oximeter uses the Beer-Lambert law to calculate the amount of light absorbed by the tissue at each wavelength, and then uses a mathematical algorithm to determine the oxygen saturation based on these measurements.

Overall, pulse oximetry is a non-invasive and relatively simple method for monitoring a patient's oxygen saturation in real-time, which is a critical parameter in many medical situations.

The maximum pressure the rectangular block can exert on a surface when placed on one of its faces on a horizontal surface is 317.71 Pa.

The maximum pressure the rectangular block can exert on a surface occurs when it is placed on one of its smallest faces.

To calculate the maximum pressure, we need to find the weight of the block, which is equal to its mass multiplied by the acceleration due to gravity. The mass of the block can be calculated as follows:

mass = density x volume

The volume of the block is:

volume = length x width x height

volume = 6.0 cm x 8.0 cm x 12.0 cm

volume = 576 cm³

Converting to meters:

volume = 0.006 m x 0.008 m x 0.12 m

volume = 5.76 x 10^-5 m³

Therefore, the mass of the block is:

mass = density x volume

mass = 2700 kg/m³ x 5.76 x 10^-5 m³

mass = 0.1555 kg

The weight of the block is:

weight = mass x acceleration due to gravity

weight = 0.1555 kg x 9.81 m/s²

weight = 1.526 N

When the block is placed on one of its smallest faces, the area of contact with the surface is:

area = length x width

area = 6.0 cm x 8.0 cm

area = 48 cm²

Converting to meters:

area = 0.06 m x 0.08 m

area = 0.0048 m²

Therefore, the maximum pressure the block can exert on the surface is:

pressure = weight / area

pressure = 1.526 N / 0.0048 m²

The star is 1.61 times brighter when measured using a V filter than when using a B filter.

We need to use the formula for magnitude difference:

\(m2 - m1 = -2.5 log (F2/F1)\)

where m1 and m2 are the magnitudes measured through filters 1 and 2, respectively, and F1 and F2 are the fluxes measured through filters 1 and 2, respectively.

We know that the (B-V) color index of the star is 0.55, which means its V magnitude can be found by subtracting this value from its B magnitude:

\(V = B - (B-V) = 5.09 - 0.55 = 4.54\)

Now, we can use the formula to find the magnitude difference between the B and V filters:

\(m2 - m1 = -2.5 log (F2/F1)\\\4.54 - 5.09 = -2.5 log (F2/F1)\\\0.55 = 2.5 log (F2/F1)\\\log (F2/F1) = 0.22\\\F2/F1 = 1.61\)

Answer: False.Machine efficiency is a measure of how much work is produced by a machine compared to how much energy is required to operate the machine.

The ratio of useful output work divided by the total input work is known as machine efficiency. This number is frequently expressed as a percentage (100 x work output / work input).Example:

For example, if you lift a 50-pound weight 10 feet in the air using a pulley, the work done is 500 foot-pounds. However, if it took 600 foot-pounds of energy to lift the weight, the pulley system's efficiency would be calculated as follows: 500/600 = 0.83 or 83 percent.

The efficiency of a machine is always less than one, in general. It is defined as the ratio of output energy to input energy. Because of losses due to friction and other variables, the output energy is always less than the input energy. As a result, the efficiency of a machine is always less than one.Answer: False.

The average torque supplied by the disk drive to the computer hard disk during the acceleration is approximately 1.04 x 10^(-3) N·m (Newton meters).

To calculate the average torque, we can use the rotational version of Newton's second law, which states that the torque (τ) is equal to the moment of inertia (I) multiplied by the angular acceleration (α). In this case, the disk starts from rest and reaches its operating speed, so the angular acceleration is given by α = ω/t, where ω is the final angular velocity and t is the time taken to reach that velocity.

The moment of inertia for a disk rotating about its central axis is given by \(I = (1/2) * m * r^2\), where m is the mass of the disk and r is the radius of the disk.

Given that the disk has a diameter of 2.5 inches (6.35 cm), the radius is half of that, which is 3.175 cm or 0.03175 m. The mass of the disk is 7.50 g, which is 0.0075 kg.

The final angular velocity can be calculated by converting the operating speed from rpm to rad/s. Since 1 rpm is equivalent to 2π/60 rad/s, the final angular velocity is (7200 rpm) * (2π/60) = 754.16 rad/s.

The time taken to reach the operating speed is given as 2.60 s.

Substituting these values into the equations, we have\(I = (1/2) * 0.0075 kg * (0.03175 m)^2 = 1.23 x 10^(-6) kg·m^2\) and ω = 754.16 rad/s.

Using the equation τ = I * α = I * (ω/t), we can calculate the average torque as τ = (1.23 x 10^(-6) kg·m^2) * (754.16 rad/s / 2.60 s) ≈ 1.04 x 10^(-3) N·m.

Therefore, the average torque supplied by the disk drive to the computer hard disk during the acceleration is approximately 1.04 x 10^(-3) N·m.

Explanation:

In the equation you get 2.88 but you round that to the nearest tenth so you get 2.9

The new temperature of the sample would be 60°C.

If the sample's temperature is doubled, we can use the formula

T₂ = 2×T₁

where T₁ is the initial temperature and T₂ is the new temperature.

Plugging in T₁ = 30°C, we get T₂ = 2×30°C = 60°C.

To understand why the new temperature is 60∘C, we need to look at the relationship between temperature and heat. Temperature is a measure of how hot or cold an object is, while heat is the energy transferred from one body to another due to a temperature difference.

In this experiment, we can assume that the sample is an isolated system, which means that there is no heat transfer between the sample and its surroundings. This is known as an adiabatic process. When we double the sample's temperature, we are essentially increasing the internal energy of the system. This increase in internal energy causes the molecules in the sample to move faster, which results in an increase in temperature.

We can use the ideal gas law to further understand this relationship. The ideal gas law states that

PV = nRT,

where P is pressure, V is volume, n is the number of moles of gas, R is the gas constant, and T is temperature. When we double the temperature of the sample, we are effectively doubling the value of T in the equation. Since the other variables are constant, the pressure or volume of the sample must change in order to maintain the equation. However, since the sample is assumed to be an isolated system, there is no change in pressure or volume. Therefore, the only variable that changes is the temperature, which doubles from 30°C to 60°C.

In conclusion, the new temperature of the sample would be 60°C if its initial temperature is doubled. This is due to the relationship between temperature and internal energy, as well as the ideal gas law.
