Answer:
The maximum temperature is 90.06° C
Explanation:
Given that
t= 0.1 mm
Heat generation
Heat transfer coefficient
Here one side(left side) of the wall is insulated so the all heat will goes in to right side .
The maximum temperature will at the left side.
Lets take maximum temperature is T
Total heat flux ,q
So the total thermal resistance per unit area
R=0.002 K/W
We know that
q=ΔT/R
30=(T-90)/0.002
T=90.06° C
The maximum temperature is 90.06° C
Answer:
4m/s approx
Explanation:
Step one
Given data
m1=71kg
m2=65kg
v1=3.4m/s
v2=??
We are required to find the Velocity of the second person
By applying the conservation of momentum principles
P=mv
m1v1=m2v2
Substitute
71*3.4=61*v2
241.4=61v2
Divide both sides by 61
v2=3.95m/s
v2=4m/s approx
Potential Energy is a type of energy that is "possessed" by a body of its position, electrical charge, etc.
