Hello!
The slope of the line given by graphing pressure vs 1/Volume at constant temp for one mole of gas will give you the value for nRT from equation PV=nRT
So set nRT=slope and take the constant number mole of gas and the constant temp and solve for R the universal gas constant. You arm for pressure and litters for volume to get R in units of L*atm/mol*k
Hope this helps you! Thanks!!
Answer:
the result = g .The correct answer is d
Explanation:
For this problem let's start by finding the center of mass of objects
= 1 / M ∑
we apply this equation to our case
M = m + 2m + 3m
M = 6m
x_{cm} = 1 / 6m (x₁ m + x₂ 2m + x₃ 3m)
x_{cm} = 1/6 (x₁ + 2 x₂ + 3x₃)
We apply Newton's second law to this center of mass
dp / dt = M a
d (M v_{cm}) / dt = M a
let's find the speed of the center of mass
v_{cm} = 1 / 6m (m v + 2m 0 - 3m v)
v_{cm} = ⅓ v
M d v_{cm}/ dt = M a
d v_{cm} / dt = a
at the center of mass the external force of the system is applied, which is the force of gravity
dv_{cm} / dt = g
therefore the result
a = g
The correct answer is d
Because gas particles in the air like particles of all fluids are constantly moving and bumping into things, they exert pressure. The pressure exerted by the air in the atmosphere is greater close to Earth's surface and decreases as you go higher above the surface.
<u>Explanation</u>:
- Fill roughly one-third of a cup with water. Then, cover the mouth of the cup completely with a flat, hard cardboard. Using your hand to keep it in place, turn the cup upside down. When you remove your hand, the the cardboard stays in place.
-
One would expect that due to gravity, the water will fall, and even the cardboard will. However, it does not, which means that something must be applying an upward force on the cardboard. This is nothing other than air pressure, which applies a force across the surface of the cardboard in an upward direction.
- Thus we can demonstrate that air exerts pressure, because otherwise, the water would have fallen.
Answer:
B) 71.5 [km]
Explanation:
To solve this problem we will decompose each of the directions in the x & y axes.
To solve this problem we will decompose each of the directions in the x & y axes. also for a greater understanding of the angles, you should look at the attached image, which contains the orientations for each angle (clockwise or counterclockwise).
<u>59.0 km in a direction 30.0° east of north</u>
<u />
<u>58.0 km due south</u>
<u />
<u>It flies 100 km 30.0° north of west</u>
<u />
<u /><u />
<u />
Now we sum algebraically the components
Using the Pythagorean theorem we can find the magnitude of the displacement.
Answer:
I suppose because buttering a cake pan reduces the amount of friction that occurs when taking the finished-baked cake out of the pan.
