What's the example you are talking about?
Answer:
Explanation:
We know that the work could be calculate dby:
W =
where is the component of the force in the direction of the
displacement. and d is the displacement.
So, the total work () is:
Where is the force done by the first tugboat, is the angle of the force, d is the displacement and is the force done by the second tugboat.
Dr. Hewitt's experiment using the bowling ball to showcase the relationship between <em>momentum, energy and speed</em> of a body in motion. In his first attempt, the ball returns and stops almost exactly at the point it was launched.
- In Dr.Hewitt's first trial with the bowling ball, the ball was launched without any additional force applied, hence, the initial energy during the launch was converted to same amount of potential energy on the ball's return. Hence, stopping at the same point where the ball was launched.
- In subsequent trials, when extra force was applied, the ball went past the <em>initial launch position</em> as the potential energy as the ball returned was higher.
Therefore, the ball stopped at the <em>position of initial launch</em> during the first trial.

Answer: the lattice contains 1 magnesium ion for every 2 fluoride ions.
is an ionic compound. It contains positive ions of Magnesium and and negative ions of Fluorine. To balance the +2 positive charge of one magnesium ion, two (-1) negatively charged Fluorine ions are present. Hence, The correct interpretation of is that the lattice contains 1 Magnesium ion for every 2 Fluoride ions.
