Hello!
Ok so for this problem we use the ideal gas law of PV=nRT and I take it that the scientist needs to store 0.400 moles of gas and not miles.
So if we have
n=0.400mol
V=0.200L
T= 23degC= 273k+23c=296k
R=ideal gas constant= 0.0821 L*atm/mol*k
So now we rearrange equation for pressure(P)
P=nRT/V
P=((0.400mol)*(0.0821 L*atm/mol*k)*(296k))/(0.200L) = 48.6 atm of pressure
Hope this helps you understand the concept and how to solve yourself in the future!! Any questions, please feel free to ask!! Thank you kindly!!!
Answer:
As Per Given Information
Mass of Car 4000 Kg
Acceleration of car 20m/s²
we have to find the force required to make the car car accelerate at given magnitude .
Using Formulae
- Force = Mass × Acceleration
On Putting the value we obtain
↝ Force = 4000 × 20
↝ Force = 80000 N
↝ Force = 80KN
So, the force required to maintain the given acceleration is 80 KiloNewton .
Answer:
Magma hot spot.
Explanation:
Hot spots stay always the same location because they are in the mantle, not in the crust. So, that's why hotspots stay while plates are moving over them.
