Answer:

D. When its weight is equal to the buoyant force exerted by the water.

Explanation:

A fluid exerts an upward force on a body submerged in it. This force that tends to lift the body is called floating force.

The flotation force that acts on a body submerged in a fluid is equal  to the weight of the fluid displaced by the body and acts upward passing through the centroid of the displacemented volume.

Vaselesa [24]

Answer:

12.7m/s

Explanation:

Given parameters:

Mass of diver  = 77kg

Height of jump  = 8.18m

Unknown:

Final velocity  = ?

Solution:

To solve this problem, we apply the motion equation below:

             v²   = u²  + 2gH

v is the final velocity

u is the initial velocity

g is the acceleration due to gravity

H is the height

 Now insert the parameters and solve;

       v² = 0²  +  2 x 9.8 x 8.18

     v  = 12.7m/s

When a neutrally charged atom loses an electron to another atom, the result is the creation of
asambeis [7]
ionic compound. The atom that lost the electron becomes a cation, and the atom that gains an electron becomes an anion. The cation and anion bond together because they have opposite charges to form an ionic compound. The question may be looking for just cation or anion, though.
