Only electrons can be lost or gained because the other particle, the proton, resides inside the nucleus.
What is the electrons?Particles that lose electrons obtain a positive charge as a result since they are cleared out with less adversely charged electrons to adjust the positive charges of the protons within the nucleus, atoms (and atoms) ordinarily procure charge by picking up or losing electrons.
An atom that picks up one or more electrons will show a negative charge and is called an anion. Electrons are adversely charged particles that are included in chemical responses and the arrangement of chemical bonds.

region is enclosed by the z-axis, the y-axis, the line, and the curve y = cos. When this region is rotated around the z-axis, what expression represents the volume of the solid?
The volume of the solid produced by rotating the region contained by the z-axis, y-axis, line, and curve y = cos around the z-axis is π.
How to determine volume of the solid?To find the volume of the solid generated by rotating the region enclosed by the z-axis, the y-axis, the line, and the curve y = cos around the z-axis, use the method of cylindrical shells.
The region is bounded on the left by the y-axis (x=0) and on the right by the line y=1. The height of the region is given by the curve y=cos(y) and the region is enclosed by the z-axis.
To use cylindrical shells, imagine slicing the region into thin vertical strips of thickness dy. Each strip is at a height y above the x-axis, has a height given by cos(y), and has a width given by the difference between the right and left bounds of the region at that height: 1 - 0 = 1.
The volume of each shell is then given by the formula for the volume of a cylinder:
V = 2πrhdy
where r = distance from the z-axis to the edge of the shell (i.e. the right bound of the region at that height), and h = height of the shell (i.e. cos(y)).
In this case, r is simply the value of y, since the region is enclosed by the z-axis:
r = y
h = cos(y)
dy = dy
Plugging these values into the formula for the volume of a cylinder:
dV = 2πy×cos(y)×dy
To find the total volume, we integrate this expression over the range of y values that define the region:
V = ∫[0, π/2] 2πy×cos(y) dy
Evaluating the integral:
V = 2π[cos(y) + ysin(y)]|[0, π/2]
V = 2π[(cos(π/2) + π/2sin(π/2)) - (cos(0) + 0sin(0))]
V = 2π[(0 + π/21) - (1 + 0)]
V = π
Therefore, the volume of the solid generated by rotating the region enclosed by the z-axis, the y-axis, the line, and the curve y = cos around the z-axis is π.

I need help on this, I couldn’t find the write subject for this but it’s sociology and no amount of good going answers this question properly
Sociologists use three levels of cultural complexity to study different cultures:
Surface levelIntermediate levelDeep levelWhat are these cultural complexity?Surface level: This refers to the visible and tangible aspects of culture, such as behaviors, artifacts, and symbols. Examples of surface-level cultural practices might include the way people dress, the food they eat, the language they speak, and the types of music they listen to.
Intermediate level: This level involves examining the underlying values, beliefs, and norms that inform and shape surface-level cultural practices. For example, in American culture, the value of individualism may inform the way people greet one another, with a focus on individual expression and personal space.
Deep level: This level involves looking at the underlying assumptions and worldviews that inform and shape the intermediate level of culture. For example, the deep level of American culture might include examining the history of colonization and its impact on cultural values around individualism and independence.

For large populations, 1000 is the best sample size. The given statement is False.
The ideal sample size for a population relies on a number of variables, including the size of the population, the level of population variability, and the level of accuracy required for population parameter estimates. In general, sample sizes would need to be bigger for larger populations and smaller for smaller populations. There is no universally applicable "best" sample size. When a population is too vast for all of the members or observations to be included in the test, a sample is employed in statistical analysis.

Synthetic pesticides, fertilizers, and other chemicals are used in agriculture, which has enhanced crop yields and helped feed a growing population, but it has also resulted in soil and water resource pollution, harm to non-target species, and the emergence of pests that are pesticide-resistant.

For a population of leghorn chickens, the mean number of eggs laid per chicken is 0. 70 with standard deviation 0. 20 egg. For a population of Sussex chickens, the mean number of eggs laid per chicken is 0. 50 with standard deviation 0. 10 egg. Two independent random samples of chickens were taken from the populations. The following table shows the sample statistics. Mike claims that for all samples of size 36 from the population of leghorn chickens and all samples of size 36 from the population of Sussex chickens, the mean of all possible differences in sample means (leghorn minus Sussex) is 0. 30 eggs per chicken. Is Mike’s claim correct?
Using a calculator or statistical software, we find that the p-value is very small as per hypothesis, much smaller than the conventional significance level of 0.05.
To determine if Mike's claim is correct, we need to perform a hypothesis test. Let's define the null and alternative hypotheses as follows:
Null Hypothesis: The mean difference in egg production between leghorn and Sussex chickens is not significantly different from 0.30 eggs per chicken.
Alternative Hypothesis: The mean difference in egg production between leghorn and Sussex chickens is significantly different from 0.30 eggs per chicken.
We can use a two-sample t-test to test these hypotheses. First, we need to calculate the pooled standard deviation:
sp = sqrt(((n1-1)*s1^2 + (n2-1)*s2^2)/(n1+n2-2))
where n1 and n2 are the sample sizes, s1 and s2 are the sample standard deviations, and sp is the pooled standard deviation.
Using the given information, we have:
n1 = n2 = 36
s1 = 0.20
s2 = 0.10
sp = sqrt(((36-1)*[tex]0.20^2[/tex] + (36-1)*[tex]0.10^2[/tex])/(36+36-2)) = 0.147
Next, we can calculate the t-statistic:
t = (x1 - x2 - d) / (sp * sqrt(2/n))
where x1 and x2 are the sample means, d is the hypothesized difference (0.30), sp is the pooled standard deviation, and n is the sample size.
Using the given information, we have:
x1 = 0.70
x2 = 0.50
d = 0.30
n = 36
t = (0.70 - 0.50 - 0.30) / (0.147 * sqrt(2/36)) = 5.65
Finally, we can calculate the p-value:
p = 2 * (1 - tdist(abs(t), n1+n2-2))
where tdist is the t-distribution function with n1+n2-2 degrees of freedom.
The p-value is very small, much smaller than the conventional significance level of 0.05.
Therefore, we reject the null hypothesis and conclude that the mean difference in egg production between leghorn and Sussex chickens is significantly different from 0.30 eggs per chicken. Mike's claim is not correct.

Excerpt from Ronald Reagan’s Speech on the Air Traffic Controllers Strike, 1981
This morning at 7 a.m. the union representing those who man America's air traffic control facilities called a strike. This was the culmination of 7 months of negotiations between the Federal Aviation Administration and the union. At one point in these negotiations agreement was reached and signed by both sides, granting a $40 million increase in salaries and benefits. This is twice what other government employees can expect. It was granted in recognition of the difficulties inherent in the work these people perform. Now, however, the union demands are 17 times what had been agreed to—$681 million. This would impose a tax burden on their fellow citizens which is unacceptable.

Let me make one thing plain. I respect the right of workers in the private sector to strike. Indeed, as president of my own union, I led the first strike ever called by that union. I guess I'm maybe the first one to ever hold this office who is a lifetime member of an AFL-CIO union. But we cannot compare labor-management relations in the private sector with government. Government cannot close down the assembly line. It has to provide without interruption the protective services which are government's reason for being.
