Response:
E = ρ ( R1²) / 2 ∈o R
Clarification:
Provided information
Two cylinders are aligned parallel
Distance = d
Radial distance = R
d < (R2−R1)
To determine
Express the response using the variables ρE, R1, R2, R3, d, R, and constants
Solution
We have two parallel cylinders
therefore, area equals 2 
R × l
And we apply Gauss's Law
EA = Q(enclosed) / ∈o......1
Initially, we calculate Q(enclosed) = ρ Volume
Q(enclosed) = ρ ( R1² × l )
Thus, inserting all values into equation 1
produces
EA = Q(enclosed) / ∈o
E(2 R × l) = ρ ( R1² × l ) / ∈o
This simplifies to
E = ρ ( R1²) / 2 ∈o R
Response:
The population mean is parameter = 65 c
Explanation:
In the analysis of samples and inferring population behavior, two key elements are essential.
To ascertain the population mean, we typically extract various samples and calculate their average. The average of all these means will serve as an estimate for the population mean. According to the central limit theorem, as sample sizes increase, the average of a sample tends to follow a normal distribution with an estimated mean being the sample mean.
A statistic pertains to a sample, while a parameter refers to the whole population.
In this case, 65 degrees C represents the entire population; thus, it constitutes a parameter.
Answer:
The surface area of the dog changes from A to 3A
Explanation:
It is stated that the dog's surface area has increased by a factor of 3 over four years.
We need to calculate the change in the relative surface area of the dog over this timeframe.
Let’s assume the initial surface area is A.
Since the surface area has been multiplied by 3,
it follows that the surface area after four years is equal to 3×A = 3A.
Thus, the dog's surface area transitions from A to 3A.
