Velocity of efflux through a hole does not, depend on

Explanation

According to Torricelli's theorem, the velocity of efflux, v, through a hole in the side of a container is given by the formula v = √(2gh), where g is the acceleration due to gravity and h is the height of the fluid above the hole. This implies that the velocity of efflux is dependent on the height of the fluid and the acceleration due to gravity, but not on the size of the hole. The size of the hole affects the flow rate, not the velocity. Option A is correct because the size of the hole does not affect the velocity of efflux.Option B is incorrect because height is a factor that directly influences the velocity. Option C is incorrect because acceleration due to gravity is a fundamental factor in determining the velocity of efflux. Option D is incorrect because it suggests that there are no dependencies, which is not true according to Torricelli's theorem.
