Answer:
2.2 m/s
Explanation:
<u>solution:</u>
To calculate change in stored energy at desired extension
ΔU = 1/2*k*(δx)^2
= 1/2*3700*(0.37^2-0.180^2)
= 201 N.m
use work energy theorem
ΔU = ΔK = 1/2*m*v^2 = 201
= 2.2 m/s
<u>note:</u>
calculation maybe wrong but method is correct.
Infrared waves are further apart and ultra violeet are close together
Buffers neutralize the acid and the bases
