Answer: The final volume V₂ of the container is 0.039 m³.
Explanation:
Since the temperature is constant, the gas would expand isothermally.
For isothermal expansion,
P₁V₁=P₂V₂
Where, P₁ and P₂ are the initial and final pressure and V₁ and V₂ are initial and final volume.
It is given that:
V₁ = 0.0250 m³
P₁ = 1.5 × 10⁶ Pa
P₂ = 0.950 × 10⁶ Pa
V₂ = ?
⇒ 1.5 × 10⁶ Pa × 0.0250 m³ = 0.950 × 10⁶ Pa × V₂
⇒V₂ = 0.039 m³
Hence, the final volume V₂ of the container is 0.039 m³.

In order to chase the fish the distance traveled by sea lion in time t must be equal to the distance of sea lion from the fish and distance traveled by fish in the same time.
So here we can say let say sea lion chase the fish in time "t"
then here we have
here
d1 = distance covered by sea lion in time t
d2 = distance covered by fish in the same time t
L = distance between fish and sea lion initially = 60 m
So it will take 9 s to chase the fish by sea lion

velocity of truck on road = 25 m/s along North
velocity of dog inside the truck = 1.75 m/s at 35 degree East of North
we can write the relative velocity as
now plug in the velocity of truck in this
so it is given as
direction will be given as
so with respect to ground dog velocity is 26.44 m/s towards 2.2 degree East of North

Answer: They will repel each other.
Explanation:
Two inflated balloons when rubbed with woolen cloth will lead to repeal each other because of the similar charges on both the balloons.
Rubbing both the balloons together by the woolen cloth will introduce negative charge in the balloons.
As, we know that the same charges repeal each other both of the balloons with be apart from each other.
This is due to the static electricity, the negatively charged particles jump to the positive one. When balloons are rubbed they become negatively charged.
