Answer:

The person’s kinetic energy is 1,025 J

Explanation:

Kinetic energy is a form of energy. It is defined as the energy associated with bodies that are in motion and this energy depends on the mass and speed of the body.

Kinetic energy is defined as the amount of work necessary to accelerate a body of a given mass and in a position of rest, until it reaches a given speed. Once this point is reached, the amount of accumulated kinetic energy will remain the same unless there is a change in speed or the body returns to its state of rest by applying a force.

Kinetic energy is represented by the following formula:

\(Ec=\frac{1}{2}*m*v^{2}\)

where Ec is kinetic energy, which is measured in Joules (J), m is mass measured in kilograms (kg), and v is velocity measured in meters over seconds (m/s).

In this case:

Replacing:

\(Ec=\frac{1}{2}*82 kg*(5\frac{m}{s} )^{2}\)

Solving:

Ec= 1,025 J

The person’s kinetic energy is 1,025 J

The kinetic energy of a person having a mass of 82 kg in an elevator moving at a speed of 5m/s is 1025J

a. Decreasing alpha from 0.05 to 0.01 makes the significance level more stringent. You will be less likely to reject the null hypothesis, even when it's false. This increases the probability of a Type II error, thus potentially reducing the power of the test. The power curve will shift to the left.

b. If the sample size is reduced from 90 to 50, the effect on the power curve is that it will also shift towards the left.

The power curve is a graph that shows the probability of rejecting the null hypothesis as a function of the true value of the mean.

In the given scenarios of this study, Reducing the significance level and reducing the sample size will shift the power curve to the left, indicating a decrease in the statistical power of the test.

The power of a statistical test is the probability that it correctly rejects the null hypothesis when the alternative hypothesis is true.

a) Reducing alpha from 0.05 to 0.01 means that we are more stringent in our assessment of whether the new treatment is effective.

This will result in a decrease in the power of the test, meaning that it is less likely that we will be able to detect a difference between the new treatment and the previous treatment.

b) If the sample size is reduced from 90 to 50, the effect on the power curve is that it will also shift towards the left.

This is because a smaller sample size decreases the power of the test. A larger sample size provides more information and thus makes it more likely to correctly reject the null hypothesis when the alternative hypothesis is true.

Therefore, by reducing the sample size, you are decreasing the likelihood of detecting a true effect if one exists, thus reducing the power of the test.

The process used by the body for transporting broken-down molecules is known as passive transport.

This process involves the movement of molecules in and out of cells without the use of energy or the need for ATP. Passive transport occurs through a variety of mechanisms, including diffusion, osmosis, and facilitated diffusion.

In diffusion, molecules move from an area of higher concentration to an area of lower concentration until the concentration of the molecules is equal.

Osmosis is the diffusion of water molecules through a selectively permeable membrane from a high concentration of water to a low concentration of water.

Facilitated diffusion is the process by which molecules move through protein channels in the cell membrane. This process does not require the use of energy and is a type of passive transport.

The Ksp equation for sodium bicarbonate (NaHCO3) should be written as:
Ksp = [Na+][HCO3-]

In this equation, Ksp represents the solubility product constant, [Na+] represents the concentration of sodium ions (Na+), and [HCO3-] represents the concentration of bicarbonate ions (HCO3-).

The concentration of the sodium ions and bicarbonate ions in the solution are represented by [Na+] and [HCO3-], respectively. Ksp is a constant at a given temperature and represents the product of the concentration of the ions raised to their stoichiometric coefficients in the balanced chemical equation.

This equation is useful for calculating the solubility of NaHCO3 in a given solvent, as well as predicting the formation of precipitates when two solutions containing ions that can form an insoluble salt are mixed.

If the product of the ion concentrations exceeds the Ksp value, the solution becomes supersaturated, and a precipitate forms.

In summary, the Ksp equation for sodium bicarbonate (NaHCO3) is a measure of its solubility in water, and it relates to the concentration of sodium ions (Na+) and bicarbonate ions (HCO3-) in the solution.

Answer:

48.049 kJ or 48049 J

Explanation:

Hello again.

So we know the formula \(q = mc\Delta t\). c is the heat capacity but this time, it is not given. However, water has a very well known heat capacity which is 4.184 J/(g°C). This is in fact the number we refer to a calorie which is the amount of energy you burn that can raise the temperature of 1g of water by 1°C. So, plugging in values, you get the above. But double check if I am wrong.

The amount of heat energy needed to cause this rise in temperature is 48.049 kJ or 48049 J.

Heat is the energy that moves from one body to another when temperatures are different. Heat passes from the hotter to the colder body when two bodies with different temperatures are brought together.

A given amount of matter's heat capacity is the amount of energy needed to raise its temperature by one degree Celsius.

The heat energy will be calculated by the formula

Q = m•C•ΔT

Where c is the heat capacity.

The m is the mass

T is the time

Mass is 348 grams

Temperature is 37°C

The change in temperature is 4.0°C to 37°C

The heat capacity of water is 4.184

Q = 348 x 4.184 x -33 = 48049.056.

Therefore, the amount of heat energy needed is 48.049 kJ or 48049 J.

The number of moles of Na2SO4 produced from 8.55 mol of H2SO4 is 8.55 mol.

In the balanced chemical equation for the reaction between H2SO4 and NaOH, it is shown that 1 mole of H2SO4 reacts with 2 moles of NaOH to produce 1 mole of Na2SO4 and 2 moles of H2O. The mole ratio between H2SO4 and Na2SO4 is 1:1, meaning that for every 1 mole of H2SO4, 1 mole of Na2SO4 is produced.

Therefore, when we have 8.55 mol of H2SO4, we can determine that the number of moles of Na2SO4 produced will also be 8.55 mol. This is because the mole ratio of H2SO4 to Na2SO4 is 1:1, indicating that the number of moles of the reactant is equal to the number of moles of the product.

Thus, from 8.55 mol of H2SO4, we can expect to obtain 8.55 mol of Na2SO4 based on the stoichiometry of the balanced chemical equation.

The correct option is $26785.To calculate the total cost per equivalent unit using the weighted average method, we need to consider the costs incurred in both the beginning work in process and the units added during the period.

First, let's calculate the equivalent units of production for both conversion and materials:

Conversion costs:

Beginning work in process: 400 units × 20% complete = 80 equivalent units

Units added during the period: 2,000 units × 40% complete = 800 equivalent units

Total equivalent units for conversion = 80 + 800 = 880 equivalent units

Material costs:

Beginning work in process: 400 units × 30% complete = 120 equivalent units

Units added during the period: 2,000 units × 50% complete = 1,000 equivalent units

Total equivalent units for materials = 120 + 1,000 = 1,120 equivalent units

Next, let's calculate the total costs incurred:

Conversion costs:

Beginning work in process cost: $14,880

Costs added during the period: $409,200

Total conversion costs = $14,880 + $409,200 = $424,080

Material costs:

Beginning work in process cost: $9,900

Costs added during the period: $180,080

Total material costs = $9,900 + $180,080 = $189,980

Now, we can calculate the total cost per equivalent unit:

Total cost per equivalent unit = (Total conversion costs + Total material costs) / (Total equivalent units for conversion + Total equivalent units for materials)

Total cost per equivalent unit = ($424,080 + $189,980) / (880 + 1,120)

Total cost per equivalent unit ≈ $267.85

Therefore, the correct option is $26785.

After 115.2 years starting with a 10 gram sample of strontium-90, only 0.625 grams of strontium-90 will remain due to radioactive decay.

Strontium-90 is a radioactive isotope that goes through dramatic rot with a half-existence of 28.8 years. This really intends that after each 28.8-year time frame, how much strontium-90 excess in an example is divided. To decide how much strontium-90 will be left after 115.2 years, we can utilize the accompanying recipe:

N = N0 * (1/2)^(t/T1/2)

where N is the last measure of strontium-90, N0 is the underlying sum, t is the time slipped by, and T1/2 is the half-life. Subbing the given qualities, we get:

N = 10 g * (1/2)^(115.2/28.8)

N = 10 g * (1/2)^4

N = 10 g * 0.0625

N = 0.625 g

In this manner, after 115.2 years, beginning with a 10 gram test of strontium-90, just 0.625 grams of strontium-90 will stay because of radioactive rot. This estimation shows that how much radioactive material declines over the long run, which is a significant thought in the protected dealing with and removal of radioactive materials.
