The elastic potential energy of the spring is 0.31 J
Explanation:
The elastic potential energy of a spring is given by
where
k is the spring constant
x is the compression/stretching of the spring
For the spring in this problem, we have:
k = 500 N/m (spring constant)
x = 0.035 m (compression)
Substituting, we find the elastic potential energy:

Answer: <em> a). Grip</em>
The grip is the important thing to be consider for golfer. It is the most fundamental important aspects to the game, because it provides the solid contact.
Applying the correct grip, results in better golf shots and an increased confidence to the golfer, to address the ball in the right direction.
Simply the grip is the pressure applied to the club with the hand such that the golfer feels comfortable to make a brilliant shot.
Answer:
because it’s suppose to be red like a stop light.
Explanation:
So it tells you to stop
Answer:
True.
Explanation:
Total internal reflection is bound to occur when light travels from dense medium to less dense.
From the table given in the question above, we obtained:
Refractive Index of Crown glass = 1.52
Refractive Index of Asphalt = 1.635
From the above, Crown glass has a lower refractive index when compared to Asphalt. This means that Crown glass is less dense than Asphalt.
Therefore, total internal reflection will not occur when light travels from Crown glass to Asphalt because Crown glass is less dense than Asphalt.
