Answer:

Moment of inertia and angular velocity.

Explanation:

The translational kinetic energy of an object is possessed when the object is showing rotational motion. It can be given by the formula as :

$KE=\dfrac{1}{2}I\omega^2$

Here,

I is the moment of inertia of the object

$\omega$ is the angular velocity of the object

So, the translational kinetic energy of an object is given by moment of inertia and angular velocity of the object. Hence, this is the required solution.

The water in a lake is at 5 °C. A diver measures the pressure of the water at two different depths in the lake. He repeats the m

Dmitrij [34]

The combination of depth at 10 m and the temperature of 15 °C will produce the greatest water pressure.

Explanation:

The pressure in any liquid is directly proportional to the depth of the water body. This is because, the more the depth, the more the buoyant force will be acting on the liquid surface. So if the water is kept constant at 15 °C, the volume is said to increase with increase in temperature as volume is directly proportional to the temperature. The same goes for pressure, the pressure of liquid increases with increase in temperature. So the combination of depth at 10 m and the temperature of 15 °C will produce the greatest water pressure.
