<span> The term for the depth of the water needed to make a boat afloat is called the draft of the boat. It can be measured as the distance from the water surface down the lowest point of the vessel. It can be imagined as the submerged portion of the boat during navigation.</span>
Answer:
The average speed of the Earth in its orbit is 4.74 km/s.
Explanation:
Distance between the Earth and the Sun ,r= 149.60 million km = 
Considering the movement of Earth around the Sun follows circular path.
The circumference of circular path will be give by :
Time taken by Earth to complete revolution around earth ,T= 1 year
1 year = 365 days
1 year = 31,536,000 seconds
T = 31,536,000 seconds
Speed of the Earth around the Sun :S
The average speed of the Earth in its orbit is 4.74 km/s.
You don't need both. GPE is the gravitational potential energy caused by the fact that an object is not touching the ground of the earth. KE is caused by an object moving. This problem says that the bowling ball "sits" meaning that you only need the GPE because it's not moving and it is not touching the surface. You would use the GPE equation to find how much Potential energy an object has. If you want its velocity, you would set the answer to the GPE equation equal to the KE equation to find its velocity.
Conservation means to improve something to prevent loss or decay
That's why energy can't be created or destroyed
