Answer:

b. 375 N

Explanation:

System of forces in balance

ΣFy = 0 Equation (1)

Forces acting on the board

T₁: Tension in the  left chain ,  vertical and upward

T₂ = 250 N : Tension in the right chain ,  vertical and upward

W₁ = 125 N : Weight of the  board , vertical and downward

W₂ =  500 N : Weight of the  person , vertical and downward

Calculation of the T₁

We apply the Equation (1)

ΣFy = 0  

T₁+T₂-W₁-W₂ = 0

T₁ = -T₂+W₁+W₂

T₁ = -250 N+ 125 N+ 500 N

T₁ = 375 N

Insect A moves 5.0 m/min and insect B moves
mezya [45]

Answer:

insect B by 12m

Explanation:

30min = 1800s (times by 60)

5m/min x 30min = 150m

9cm/s x 1800s = 16,200cm = 162m

162m - 150m = 12m
