Answer:
t=5.2seconds
Explanation:
First, we state our assumptions:
Given
and gas stream
We use the time constant to find the diameter of the junction:
Now, check the validity of the lumped system analysis. With
#Lumped Analysis is OK
Bi<<0.1, therefore the lumped approximation is excellent. The time required for the junction to reach :
It takes 5.2seconds for the junction to reach 199 oC

A. Bass Drum
Answer:
C = 1256.63 miles
Explanation:
This problem is solved by using the following formula for the relation between the arc length of a circle and its radius:
s: arc length
r: radius
In this case "s" is 600 miles, and the angle of the arc length is 3°. With this information you can calculate the radius of the planet X:
With the value of the radius of the planet you can calculate the circumference, by using the following formula:
1 kg = 1,000 grams
To get 75kg in units of grams, we just multiply 75 by 1,000
75* 1,000 = 75,000 grams
