Answer:
0.81452 atm
Explanation:
= Initial pressure = 1.43 L
= Volume
= Initial temperature = (28+273.15) K
= Final temperature = (-35+273.15) K
= Final pressure
From the ideal gas law we have

The pressure in the cylinder is 0.81452 atm
Answer:
2000metres
Explanation:
Pressure= density x height x gravity
Gravity is always a constant = 10N/kg
so height= Pressure/( density x gravity)
h= 20000000/(1000 x10)
h= 2000 metres
Answer: A. Radiation can move through empty space to transfer heat; conduction cannot.
Now unlike convection and conduction, radiation does not require matter to transfer heat. It also does not require a medium to transfer heat, crossing off the other options regardless.
I hope this helps!
Answer:
k = 652 lb/ft
Explanation:
Given :
Weight of the collar = 1.6 lb
The upstretched length of the spring = 6 in
Speed = 16 ft/s
PA = 8 + 10
= 18 inch
Let the initial elongation be 
∴
= 18 - 6
= 12 inch = 1 foot

= 13.925 inch
Final elongation in the spring
inch = 0.66 feet
Applying the conservation of the mechanical energy between A and B is


![$\frac{1}{2}k[(1)^2-(0.66)^2]=\frac{1.6}{2}\times (16)^2-1.6 \times 32 \times \frac{5}{12}$](https://tex.z-dn.net/?f=%24%5Cfrac%7B1%7D%7B2%7Dk%5B%281%29%5E2-%280.66%29%5E2%5D%3D%5Cfrac%7B1.6%7D%7B2%7D%5Ctimes%20%2816%29%5E2-1.6%20%5Ctimes%2032%20%5Ctimes%20%5Cfrac%7B5%7D%7B12%7D%24)

k = 652 lb/ft
