The volume occupied by the given mol of helium gas at the given temperature and pressure is 91.6L.
Given the data in the question;
Amount of helium; [tex]n = 2.59mol[/tex]Pressure; [tex]P = 0.826atm[/tex]Temperature; [tex]T = 356K[/tex]Volume of helium; [tex]V = \ ?[/tex]
Ideal Gas LawThe Ideal gas law or general gas equation emphasizes on the state or behavior of a hypothetical ideal gas. It states that pressure multiplied by volume is equal to moles multiply by the universal gas constant multiply by temperature. It is expressed;
[tex]PV = nRT[/tex]
Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant ( [tex]R = 0.08206Latm/molK[/tex] )
To determine the volume occupied by the helium gas, we substitute our values into the expression above.
[tex]PV = nRT\\\\V = \frac{nRT}{P} \\\\V = \frac{2.59mol\ *\ 0.08206Latm/molK\ *\ 356K}{0.826atm} \\\\V = \frac{75.6626L}{0.826}\\ \\V = 91.6L[/tex]
Therefore, the volume occupied by the given mol of helium gas at the given temperature and pressure is 91.6L.

Calvin deposits $400 in a savings account that accrues 5% interest compounded monthly. After c years, calvin has $658. 80. Makayla deposits $300 in a different savings account that accrues 6% interest compounded quarterly. After m years, makayla has $613. 4. What is the approximate difference in the number of years that calvin and makayla have their money invested? makayla invests her money 1 year longer. Makayla invests her money 2 years longer. Calvin invests his money 1 year longer. Calvin invests his money 2 years longer
Using compound interest, it is found that the approximate difference in the number of years that calvin and makayla have their money invested is given as follows:
Makayla invests her money 2 years longer.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year. t is the time in years for which the money is invested or borrowed.For Calvin, the parameters are given as follows:
[tex]P = 400, r = 0.05, n = 12, A(t) = 658.8[/tex]
Hence:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]658.8= 400\left(1 + \frac{0.05}{12}\right)^{12t}[/tex]
[tex]\left(1 + \frac{0.05}{12}\right)^{12t} = \frac{658.8}{400}[/tex]
[tex](1.00416666667)^{12t} = 1.647[/tex]
[tex]\log{(1.00416666667)^{12t}} = \log{1.647}[/tex]
[tex]12t\log{1.00416666667} = \log{1.647}[/tex]
[tex]t = \frac{\log{1.647}}{12\log{1.00416666667}}[/tex]
[tex]t = 10[/tex]
For Makayla, the parameters are given as follows:
[tex]P = 300, r = 0.06, n = 4, (t) = 613.4[/tex]
Hence:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]613.4 = 300\left(1 + \frac{0.06}{4}\right)^{4t}[/tex]
[tex]\left(1 + \frac{0.06}{4}\right)^{4t} = \frac{613.4}{300}[/tex]
[tex](1.015)^{4t} = 2.0447[/tex]
[tex]\log{(1.015)^{12t}} = \log{2.0447}[/tex]
[tex]12t\log{1.015} = \log{2.0447}[/tex]
[tex]t = \frac{\log{2.0447}}{4\log{1.015}}[/tex]
[tex]t = 12[/tex]
12 - 10 = 2, hence Makayla invests her money 2 years longer.

The net forces exerted on the horse and cart are the same, but they are in the same direction. The net forces exerted on the horse and cart are not the same, so the two forces cancel out. The net forces exerted on the horse and cart are not the same, so they are not balanced forces
The statement which best describes the forces acting on the horse and buggy is: D. The net forces exerted on the horse and cart are not the same, so they are not balanced forces.

Unbalanced forceBalanced forceWhat is a balanced force?A balanced force refers to a type of force that is only produced when two or more forces (net forces) that are acting on an object (buggy) are equal in magnitude and as such, it does not result in a change of motion (acceleration).
In this scenario, the net forces exerted on the horse and cart are not equal or the same in magnitude, so they are not balanced forces. Thus, resulting in a change of motion of the buggy.

In a fixed volume, when temperature decreases, pressure
Explanation:
the pressure increases. Because the temperature of a gas is proportional to the average kinetic energy of the gas molecules. The particles moving faster collide with the walls of the container frequently with greater force. This causes the force on the walls of the container to increase so as the pressure increases.

An equation can have zero or as many solutions as possible
The equation 5x + 2 − 2(x − 1) = 3x + 4 has infinitely many solutions
How to determine the number of solutions?From the complete question (see attachment), we have the following equation
5x + 2 − 2(x − 1) = 3x + 4
Open the bracket
5x + 2 − 2x + 2 = 3x + 4
Collect like terms
5x − 2x + 2 + 2 = 3x + 4
Evaluate the like terms
3x + 4 = 3x + 4
The expressions on both sides of the equation are the same.
Hence, the equation has infinitely many solutions

A person weighing 0. 70 kn rides in an elevator that has an upward acceleration of 1. 5 m/s2. What is the magnitude of the force of the elevator floor on the person?
The magnitude of the force of the elevator floor on the person is; 807.13 N
What is the Magnitude of force?We are given;
Weight; W = 0.7 KN
Acceleration; a = 1.5 m/s²
There are only two forces acting on the person: which are his weight W (downward) and the normal force N of the floor against the body (upward). Thus the equilibrium equation here is;
N - W = F
N - W = ma
Here, m is the mass of body, and its value is calculated as;
W = mg
0.7 = 9.81m
m = 0.7/9.81
m = 71.42 kg
Thus;
N - 0.7 = 71.42 * 1.5
N = 0.7 + (71.42 * 1.5)
N = 807.13 N

The table below lists the means and standard deviations for 5th graders in the district and for the norm group for student performance in four different subjects. According to the table, the performance of the 5th graders in the district is more variable than that of the norm group in which subject(s)?
Using the coefficient of variation, it is found that the performance of the 5th graders in the district is more variable than that of the norm group in Geography and Science.
What is the coefficient of variation of a distribution?It is given by the division of the standard deviation by it's mean.
Researching this problem on the internet, we have that for geography, the class mean and SD are given, respectively, by 75 and 12, while the norm is of 10 and 85, hence:
[tex]CV_c = \frac{12}{75} = 0.16[/tex]
[tex]CV_n = \frac{10}{85} = 0.12[/tex]
In English, the mean and SD are 100 and 10, respectively, for both, hence:
[tex]CV_c = \frac{10}{100} = 0.11[/tex]
[tex]CV_n = \frac{10}{100} = 0.11[/tex]
In Spelling, they are for the class of 125 and 12, for the norm 15 and 120, hence:
[tex]CV_c = \frac{12}{125} = 0.096[/tex]
[tex]CV_n = \frac{15}{120} = 0.125[/tex]
In Science, they are for the class of 90 and 20, for the norm 15 and 90, hence:
[tex]CV_c = \frac{20}{90} = 0.2222[/tex]
[tex]CV_n = \frac{15}{90} = 0.1667[/tex]
Hence the class is more variable in Geography and Science.
