Answer:
Explanation:
Work is given by the equation where
is force and
is displacement.
Displacement is defined as change in position. In this case, the box moves from 5m to 20m. Its displacement is .
The force acting on the box is the force of gravity, given as .
Therefore, the total work done is:
(two significant figures).
Answer:
V=9.60m/s
Attached is the solution
Answer:
V₂= 1 L
Explanation:
Given that
Volume occupies V₁= 6 L
Initial pressure = P₁
Initial temperature = T₁
The final pressure =P₂ = 2 P₁
Final volume =V₂
Final temperature = T₁/3
As we know that equation for ideal gas
P V = m R T
P=pressure, V=volume, T=temperature
m=mass ,R=gas constant
Now from mass conservation
6 = 3 x 2 V₂
V₂= 1 L
So the final volume will be 1 L
