During a drive by golfer Tiger Woods, the angular velocity of his club is zero at the top of his backswing and 30 rad/s at the b
ottom of his downswing just before impact with the ball. If his downswing lasts .30 s, what is the average angular acceleration of the club during the downswing?

The displacement is the straight-line distance it flew when everything is over. We don't count all of the turns that it made in the displacement. So if it's in an opposite corner we just need to know how far it is from one corner of a box to the opposite corner with the given dimensions. We use the Pythagorean Theorem for part a):
b). Since the displacement is the straight line path, there are no shorter paths that this.
c)All other paths are greater
d) if the fly flies this path, then they would be equal
in cartesian coordinates, the vector is the sum of the 3 components whose magnitudes are the wall lengths and whose directions are parallel to that wall:
The shortest walking path is 7.96m.

As we know that power is defined as rate of work done
so we will have
so in order to increase the power as per above formula we know that either we need to increase the work or we need to decrease the time to complete that work
So here the correct answer will be
increase the work being done or decrease the time in which the work is completed.
First, when the student added the layers of wax over each other, this became a representation of sedimentary rocks.
Then the student folded his/her palm and squeezed the layers of wax. This means that the student applied heat and pressure on the wax (sedimentary rocks)
Referring to the diagram below which represents the rock cycle, we will find that applying heat and pressure on sedimentary rocks would convert these rocks into metamorphic rocks.
Based on the above, the best choice would be:
<span>d. Heat and pressure can change sedimentary rocks into metamorphic rocks.</span>
