High rates of attrition is particularly problematic for longitudinal research.

There are two major issues with attrition. First, attrition reduces the size of the sample, and when the sample size is too low, statistical power is compromised. In the event that attrition is not random, it may also result in non-response bias (which affects the validity of the study findings).

High rates of observation, generalization, attrition, and deception complicate longitudinal studies. So, a longitudinal study is one in which a group of people is followed over an extended period of time.

Attrition rates or churn rates typically show how quickly employees change jobs, while low attrition rates show how long employees stay with a company. The size of your business will also affect the employee attrition rates.

Through ATP synthase, the hydrogen ions return down the gradient of their concentration. This causes the subunits to spin and generates the energy required for the fusion of ADP and inorganic phosphate to produce ATP.

In order to move hydrogen ions from the matrix into the intermembrane gap via the mitochondrial inner membrane during electron transport, energy is required. Through the action of ATP synthase, hydrogen ions move back across the mitochondrial membrane and into the matrix as a result of a chemiosmotic gradient, producing ATP.

A H+ accumulation occurs in the inner membrane space of the mitochondria as a result of the electrons from NADH and FADH2 moving through the electron transport chain. The membrane enzyme complex ATP synthetase receives its direct energy for ATP production from the proton gradient (gradient of H+) that flows through it.

The specific heat capacity of the metal is 0.17 J/g*C.

To determine the specific heat capacity of the metal, we can use the formula:

Q = mcΔT

Where Q is the heat absorbed or released, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature.

We know that the heat absorbed by the metal is equal to the heat lost by the water:

Qmetal = Qwater

We know the mass of the water, the initial and final temperature of the water, and the mass of the metal and the initial and final temperature of the metal. We can use this information to calculate the heat absorbed by the water and the heat absorbed by the metal.

Qwater = mwater * cwater * ΔTwater

Qmetal = mmetal * cmetal * ΔTmetal

We know that the heat absorbed by the metal is equal to the heat lost by the water, so we can set the two equations equal to each other:

mwater * cwater * ΔTwater = mmetal * cmetal * ΔTmetal

And we know that the specific heat of water is 4.18 J/g*C and the mass and the initial and final temperature of the water and the mass and the initial and final temperature of the metal

cmetal = mwater * cwater * ΔTwater / mmetal * ΔTmetal

cmetal = (140.0 g * 4.18 J/gC * (24.6 - 25.0)°C ) / (120.9 g * (24.6 - 100)) = 0.17 J/gC

None of the above is right option for the same. A wave in which particles of the medium undergo a circular motion is known as a Surface wave.

A surface wave is a wave in which the medium's particles move in a circular pattern. Surface waves are neither transverse nor longitudinal. All of the particles in the bulk of the medium travel parallel to and perpendicular to the direction of energy transport in longitudinal and transverse waves, respectively.

Only the particles at the medium's surface move in a circular motion during a surface wave. As one moves farther away from the surface, the mobility of the particles tends to slow down.

Every wave that travels across a medium has its origin. One of the particles was initially displaced somewhere along the medium.

It is typically the first coil on a slinky wave that is moved by a person's hand. The first air particle to vibrate during the creation of a sound wave is often caused by the vocal chords or a guitar string.

Answer: Diamond has a refractive index of 2.42 which means that the speed of light in diamond will reduce by a factor of 2.42 as compared to its speed in the air. In other words, the speed of light in diamond is 1/2.42 times the speed of light in vacuum.

Answer:

The refractive index of a material is a measure of how much a material bends light as it passes through it. The refractive index of a material is defined as the ratio of the speed of light in a vacuum to the speed of light in the material. A refractive index of 2.42 for diamond means that light travels through diamond at about 42% slower than it does in a vacuum. This high refractive index is due to the high density and strong chemical bonds of the carbon atoms in diamond. This high refractive index gives diamond its characteristic brilliance and fire, and makes it

If three or more points fall along a single straight line, they are said to be collinear. An axis is a term used to describe a line on which points are located, particularly if that line is connected to a triangle or other geometric shape. Since two points determine a line, two points are trivially collinear.

It is not always possible for the three spots to coincide. This indicates that depending on where these points are located in a plane, they may be collinear or noncollinear. If the slope between any two pairs of points is equal, three points are said to be collinear.

The voltage across R2 calculated by taking the difference is 5 V.

We know that the total voltage of a battery is equal to the sum of the voltages across each resistor in a series circuit.

Voltage =Vr1 + Vr2

Voltage = 12 V

Voltage across R1 = 7 V

Therefore,

Voltage across R2 = Voltage - Voltage across R1

Voltage across R2 = 12 V - 7 V = 5 V

It's important to note that in a series circuit, the same current flows through each resistor. Therefore, the voltage across each resistor is inversely proportional to its resistance. In other words, the resistance of R2 is greater than R1, so the voltage across R2 is less than the voltage across R1.

Answer:  A big Yes

Explanation: Viscosity depends strongly on temperature. In liquids, it usually decreases with increasing temperature, whereas, in most gases, Viscosity increases with increasing temperature.

As temperature increases, the average kinetic energy of the molecules also increases; it more easily overcomes the attractive forces between molecules. Therefore, Viscosity decreases with increasing temperature.

For example, when syrup is cold it has a high viscosity and can be difficult to pour. When heated in a microwave, the viscosity decreases and the syrup flows more freely. Similarly, Honey and oil tend to flow better at higher temperatures.

Both cohesion and molecular interchange contribute to liquid viscosity.  With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same.

When a liquid is heated, the kinetic energy of its molecules increases and the intermolecular attraction becomes weaker. Hence, the viscosity of a liquid decreases with an increase in its temperature.
