Answer:
160N
Explanation: When 80kg mass is one group . It's reaction force acting on a ground.
Weight of the object = 80*10
= 800 N
Here we are given cofficient of static friction its 0.2. It should be smaller than 1
Friction force = Reaction * Friction Cofficient
Reaction = 800N ( Considering Vertical Equilibrium )
F = 800* 0.2
F = 160N
Answer:
4N to the left. No it is not balanced.
Explanation:
8 -4 = 4 N of force
Balanced would be if they equaled zero, so 8 to the left and 8 to the right
Wooden desk it doesn’t conduct or absorb heat as much as metal or plastic
Answer:
D. Output force
Explanation:
The input force is the effort used to run the machine and this results in an output force.
