Answer: The outer surface temperature is .
Explanation:
Given: Heat = 3 kW (1 kW = 1000 W) = 3000 W
Area = 10
Length = 2.5 cm (1 cm = 0.01 m) = 0.025 m
Thermal conductivity = 0.2 W/m K
Temperature (inner) =
Formula used is as follows.
where,
K = thermal conductivity
A = area
L = length
= inner surface temperature
= outer surface temperature
Substitute the values into above formula as follows.
Thus, we can conclude that the outer surface temperature is .
Answer: Why is even here then.
Explanation:
Answer:
3.75 amps per volts
Explanation:
Convert to a decimal by dividing the numerator by the denominator??
By applying the concepts of differential and derivative, the differential for y = (1/x) · sin 2x and evaluated at x = π and dx = 0.25 is equal to 1/2π.
<h3>How to determine the differential of a one-variable function</h3>
Differentials represent the <em>instantaneous</em> change of a variable. As the given function has only one variable, the differential can be found by using <em>ordinary</em> derivatives. It follows:
dy = y'(x) · dx (1)
If we know that y = (1/x) · sin 2x, x = π and dx = 0.25, then the differential to be evaluated is:
By applying the concepts of differential and derivative, the differential for y = (1/x) · sin 2x and evaluated at x = π and dx = 0.25 is equal to 1/2π.
