Measurements show that the active proteins within a muscle cell such as myosin and actin can produce a force of about 7.5 pN and displacements of 7.0 nm Submit My Answers Give Up Signed in as fahad alkaltham Help l Close Resources previous l 9 of 10 l next Provide Feedback Continue

Explanation / Answer

we know, Workdone = F*d*cos(theta) (here F is force, d is displacemtn and theta is the angle between F and d)

= 7.5*10^-12*7*10^-3

= 5.25*10^-14 J
