Answer:
C
Explanation:
Vector A points up
Vector B points right
The combination must be both up and right which is C
Well, it would be fossilization. <- If I spelled it correctly.
Supposing that the spring is un stretched when θ = 0, and has a toughness of k = 60 N/m.It seems that the spring has a roller support on the left end. This would make the spring force direction always to the left
Sum moments about the pivot to zero.
10.0(9.81)[(2sinθ)/2] + 50 - 60(2sinθ)[2cosθ] = 0 98.1sinθ + 50 - (120)2sinθcosθ = 0 98.1sinθ + 50 - (120)sin(2θ) = 0
by iterative answer we discover that
θ ≈ 0.465 radians
θ ≈ 26.6º
Answer:
61.0168 g/mol Explanation:
Yes, you're correct. If you put all of them on the K scale, then 0C is at 273, 0F is at 255, and 0K is at zero.
