A would be the wavelength, C would be a crest, D would be the amplitude, leaving B which is the trough.

Answer: B. B

Explanation:

The trough is B because it is the "minimum" amplitude of a wave since amplitude is D which is the displacement of wave from its initial position. The minimum value of the amplitude will be at B which is the trough.

Note that the maximum value of the amplitude will be the crest which at C.

How do you calculate the net force when there are multiple forces in different directions?

Artyom0805 [142]

To find $F_{net}$ we need to use vector addition and use the x and y components. First we subtract vector 2 from vector 5 which results in a vector with a length of 3 pointing directly east, then we use the distance formula to find the length of the net force $F_{net} = \sqrt{(3)^2+(4)^2} \\$ which gives $F_{net} = 5$ . We now have a magnitude but we also need a direction, since vector 4 and vector 5 are perpendicular. Using $\theta = \tan^{-1} (\frac{4}{3})$ where tan^-1(y/x) we get an angle of 53 degrees. The resultant force vector is 5 distance with an angle of 53 degrees north east.
