Answer:
V₂=4.57 x 10³ L
Explanation:
Given that
V₁= 2.88 x 10³ L
P₁=722 mm Hg
T₁ = 19°C
T₁ =292 K
P₂=339 mm Hg
T₂= - 55°C
T₂=218 K
Lets take final volume = V₂
We know that ideal gas equation
PV = m R T
By applying mass conservation


V₂=4.57 x 10³ L
Therefore volume will be 4.57 x 10³ L
The object is at rest.
This is due to the fact hwen two forces act upon each other on opposite sides, the movement of the object does not change due to the net force equaling 0.
Applying
v=u+a.t
(all the symbols are bearing their conventional meaning)
Here,u=2ms−1,t=5,a=4ms−2
So,v=2+4⋅5=22ms−1
