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
Electromagnetic force between the molecules!
Answer:
The main reason is that very young calves are more noticeable to predators when mixed with older calves from the previous year
Explanation:
<span>"Time is like wax, dripping from a candle flame. In the moment, it is molten and falling, with the capability to transform into any shape.

It becomes the past, a solid single record of what happened, still holding in its wild curves and contours the potential of every shape it could have held."</span>
