I have to draw a wave on a separate sheet of paper given the following measurements down below. I'm a bit confused, do I just us
e a ruler and make the crest 1 cm long across along with the trough and wave length like I did in the pic. Did I do it correctly?
Wave #1:
1 cm Crest
1 cm Trough
2 cm Wavelength
Wave #1:
1 cm Crest
1 cm Trough

Answer:
The solution and the explanation are in the Explanation section.
Explanation:
According to the diagram that is in the attached image, the EFFORT force at point A and the load is at O point. The torque due to weight is:
TA = W * (a * cosθ)
The torque due to effort at C point is:
TC = E * (b * cosθ)
The net torque is equal to 0, we have:
Tnet = 0
W * (a * cosθ) - E * (b * cosθ) = 0
From the figure, you can observe that a/b < 1, thus E < W
Answer:
195.168 m
Explanation:
To find the magnitude of the vector you can use the Pythagorean Theorem since you have the height and base and the vector is really just the hypotenuse
Pythagorean Theorem:
Plug values in
Simplify
Add the two values
Take the square root of both sides
