Answer: option D) 42.4 N
The weight of the frame is balanced by the vertical component of tension.
W = T sin θ + T sin θ = 2 T sin θ
The tension in each cable is T = 30 N
Angle made by the cables with the horizontal, θ = 45°
⇒ W = 2×30 N × sin 45° = 2 × 30 N × 0.707 = 42.4 N
Hence, the weight of the frame is 42.4 N. Correct option is D.
Answer: Scientists believe the missing carbon has found a sink in the Northern Forest. Scientist have come up with this idea because they believe consequences of global warming contributed to significant extent to the northern forest carbon sinking processes.
