if 1.5kg block is pulled across a horizontal surface that has a coefficient of kintic friction of 0.60. if a block is pulled by a 12n force, what is the net force acting on the block
Answer:
3.2N
Explanation:
Given parameters:
Mass of block = 1.5kg
Coefficient of kinetic friction = 0.6
Force of pull on block = 12N
Unknown:
Net force on the block = ?
Solution:
Frictional force is a force that opposes motion:
Net force = Force of pull - Frictional force
Frictional force = umg
u is coefficient of kinetic friction
m is the mass
g is the acceleration due to gravity
Frictional force = 0.6 x 1.5 x 9.8 = 8.8N
Net force = 12N - 8.8N = 3.2N
What is one way skin, muscle, and nerve cells similar?
Answer:
For starters the membrane voltage is the same in nerve cells as in muscle cells.
As for skin and muscle cells, both cells arise from the same type of embryonic layer, the ectoderm and both which produces energy, though skin cells eventually lose their organelles.
