Answer 1

Answer:

1)

Frustum A.

2)

The liquid pressure increases as depth increases.

3)

The ball will accelerate as the velocity changes.

Explanation:

1)

Frustum A is somewhat more streamlined and it'll be easy for it to go deeper because of its shape.

2)

This shows us that water pressure increases as depth increases because the water is coming out with more pressure from the bottom and with less pressure from the top. the equation for this relation is p= h×rho×g where p is pressure, h is height, rho is density and g is the gravitational force.

3)

As we apply the force on the ball from the left side the ball following the Newton's third law of motion will move in the opposite direction accelerating as it changes its initial velocity from 0 m/s to unknown m/s
