A Myocyte is probably the best answer for this question
Answer:
a) 0.040625 m
b) 5.02272 J
Explanation:
k = Spring constant
x = Stretched length
F = Force
a)


Extension of the spring would be 0.040625 m
b) Work done in a spring

The work done by the shopper to stretch this spring a total distance of 8.00 cm is 5.02272 J
The answer is refraction. When a wave from one medium enters another medium, its direction changes due to the change of speed (phase velocity changes but frequency remains the same). The wave slows down when it enters a denser medium from the one it came from hence its path seems to bend.
Answer = 6.24x10^18 x ((2 x 3600) + (47 x 60) + 10)
A ) <em>Speed</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>scalar quantity and velocity is a vector quantity.</em>
