The spring constant is 147 N/m
Given the mass of the block is 2.00 kg , the mass of the body is 300 g and the length of the spring is 2.00 cm
We need to find the spring constant
A spring is an object that can be deformed by a force and then return to its original shape after the force is removed.
The force required to stretch an elastic object such as a metal spring is directly proportional to the extension of the spring
We know that F = kx
300(9.8)= k (0.02)
k = 147.15 N/m
Rounding off to the nearest is 147N/m
The spring constant is 147N/m

Answer:
r = 22.3 cm
Explanation:
given,
angular speed = 45 rev/s
tangential speed = 63 m/s
length of the rotating string
angular velocity =
ω = 2 π N
ω = 2 π x 45
ω = 282.74 rad/s
we know,
v = r ω
r = 22.3 cm
The answer is C, because it hits a dense medium, which causes it to bounce off.
Hope I helped. :)
No, since their gravity is powerful enough to keep them together even while the universe expands as a whole. Space is not expanding within clusters of galaxies.
<h3>What is a galaxy?</h3>
A galaxy is a massive clump of gas, dust, and billions of stars and their solar systems bound together by gravity.
No, since their gravity is powerful enough to keep them together even while the universe expands as an entire.
Hence,space is not expanding within clusters of galaxies.
