a typical muscle fiber is 2.0 cm long and has a cross-section area of 3.1×10−9m2. when the muscle fiber is stimulated, it pulls with a force of 1.2 mn.

Respuesta :

The muscle fiber expends 4.80 x 10 J worth of energy. When the cross-sectional area of a typical muscle fiber is 3.1109m2 and it is 2.0 cm long.

What three types of muscle fibers are there?

Slow oxidative (SO), fast oxidative (FO), and quick glycolytic are the three different types of muscle fibers (FG). All three types are present in the majority of a human's skeletal muscles, though in varied amounts.

When a muscle fiber contracts to a length, it works on:

W= F.d

F = 1.2 x 10-3N

d= (2-1.6)10-2=0.004m

W=1.210-3(0.004)=4.8 x 10 -6 J
