<u>B</u> option is correct .
assuming north-south along the Y-axis and east-west along the X-axis
X = total X-displacement
from the graph , total displacement along X-direction is given as
X = 0 - 20 + 60 Cos45 + 0
X = 42.42 - 20
X = 22.42 m
Y = total Y- displacement
from the graph , total displacement along Y-direction is given as
Y = 40 + 0 + 60 Sin45 + 50
Y = 90 + 42.42
Y = 132.42 m
magnitude of the net displacement vector using Pythagorean theorem is given as
magnitude : Sqrt(X² + Y²) = Sqrt(22.42² + 132.42²) = 134.31 m
Direction : tan⁻¹(Y/X) = tan⁻¹(132.42/22.42) = 80.4 deg north of east
Use direct proportionality: If 1.25 m = 72 N, then 0.55 m = y
0.55 m × 72 = 39.6.
39.6÷1,25 gives you your answer which is 31.68 N.
Answer:

A Eukaryotic cell
Explanation:
Animal cells don’t have cell walls and prokaryotic cells don’t have nuclei
C. Wavelength is the length of one complete wave cycle 
Wavelength of a sine wave, λ, can be measured between any two points with the same phase, such as between crests, or troughs, or corresponding zero crossings as shown
