Which group includes the most complex body structures A: cardiac tissue, bone marrow, Epithelial tissue
B: neuron, White blood cell, smooth muscle cell
C:Brain cells, red blood cells, white blood
cell
D: skin, small intestine, lungs

C.

explanation: Brain cells are the most complex body structure because they control everything.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
