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

The closeness of measured values to an accepted value is the BLANK of the data ?
wlad13 [49]
When you refer to how close a measured value is to a standard, accepted or known value, you are talking about the ACCURACY of the data. This is the definition of accuracy when it comes to engineering and other fields of science. 

Accuracy is usually associated or with the term precision, as their definitions are often interchanged.
