Answer:
b) Springs oscillate with the same frequency,
Explanation:
expression for frequency of vibration of mass hanging from a spring is given as follows
f =
k is force constant of spring and m is mass vibrating .
In the present case, if mass stretches the spring by x and remains balanced
mg = k x
g and x are same for both cases
will also be same for both cases .
Hence frequency of vibration will also be same for both the balls .
Technology has affected almost every aspect of modern sports.
Answer: Option A
<u>Explanation:</u>
Modern sports consists of outdoor games and games related to having physical exercise of the body. But nowadays, technology had made the outdoor games as video games and these video games are so realistic to view that it makes the player addicted and attracted to the video games.
So in this technology, the player should use less or no physical strength to win a video games related to modern sports instead it is played on smart phones, laptops or other visible devices.
Thus, the environment of playing in a group and doing physical work for playing different games are mostly affected with rise in technology which produced realistic video games. Thus technology affects the aspects of modern sports.
Answer:
212.5 N/m
Explanation:
Work, W = 1700 J
y1 = 2 m
y2 = 6 m
y = y2 - y1 = 6 - 2 = 4 m
Let K be the spring constant.
Work done is given by
W = 1/2 Ky²
1700 = 0.5 x K x 4 x 4
K = 212.5 N/m
Thus, the spring constant is given by 212.5 N/m.
