The answer would be Conduction
Answer:
The magnitude of the velocity is approximately 11.45 units
Explanation:
Since they give us the x and y components of the vector velocity, we can find its magnitude via the Pythagorean theorem:

Answer:
at its centre
Explanation:
The centre of gravity is a point inside the body where entire weight os the body is said to be concentrated. For geometrical symmetric bodies it lies at the geometric centre of the body.
The base ball is a spherical body, so its centre of gravity lies at its centre.
