Suppose the temperature inside a three dimensional ball is proportional to the square root of the distance from the center. Find
sesenic [268]

Answer:

The formula for the average temperature in the ball is \bar T = \frac{2\cdot k\cdot R^{1/2}}{3}. The limit of the average temperature for the ball does not exist.

Step-by-step explanation:

According to the statement, we have the following direct relationship:

T \propto \sqrt{r}

T = k\cdot \sqrt{r} (1)

Where:

T - Temperature, measured in degrees Celsius.

r - Distance from the center, measured in meters.

k - Proportionality constant, measured in degrees Celsius per meter.

Under the assumption that ball is a continuous entity, we find that average temperature in the ball (\bar T), measured in degrees Celsius, is represented by the following integral equation:

\bar T = \frac{1}{R}\cdot \int\limits^{R}_{0} {T(r)} \, dr (2)

By applying (1) in (2), we find that:

\bar T = \frac{k}{R}\cdot \int\limits^{R}_{0} {\sqrt{r}} \, dr

\bar T = \frac{2\cdot k}{3\cdot R}\cdot (R^{3/2})

\bar T = \frac{2\cdot k\cdot R^{1/2}}{3}

If the ball gets larger, then the limits associated to the average temperature diverges to the infinity as maximum exponent of the numerator of the rational function (n = \frac{1}{2}) is greater than the maximum exponent of the denominator (n = 0). Therefore, the limit of the average temperature for the ball does not exist.

At Chester’s Bakery, a box of 12 donuts sells for $8.50. What is the unit price of the donuts in the box, rounded to the nearest
Romashka-Z-Leto [24]
$.71 per donut because you divide $8.50 by 12 and it determines the price of one :)

Give three numbers whose product is 9000
Klio2033 [76]
<span>Product means, the answer of numbers being multiplied with each other.
In the given situation, we need to find three numbers that will be multiplied with each other to get a product which is 9000.</span> <span>Now, let’s find the possible numbers to be multiplied:
=> 300 X 30 X 1
=> 9000 x 1
=> 9000

Or this one also applies:
=> 4500 x 2 x 1
=> 9000 x 1
=> 9000</span> There are a lot of ways to get a product of 9000 by multiplying 3 digits.
