The work-done by the wind as the bug undergoes the displacement is 80 J.
The given parameters;
- Mass of the bug, m = 45 g
- Force exerted, F = (4.0 î – 6.0j) x 10⁻² N
- Displacement of the bug, r = (8.0î - 8.0j) m
The work-done by the wind as the bug undergoes the displacement is obtained by finding the dot product of the force and the displacement;
Work done = F. r
Work done = (4.0 î – 6.0j) x 10⁻² . (8.0î - 8.0j)
Work done = (32i²) + (48j²)
Work done = 32(1) + 48(1)
Work done = 80 J.
Thus, the work-done by the wind as the bug undergoes the displacement is 80 J.

Displacement is the distance between the starting and ending points, in the direction from the starting point to the ending point, all regardless of the route followed from the starting point to the end point.
The woman's displacement is therefore 30 meters north.
Answer:
C. reflects one or more visible light frequencies.
Explanation:
The color that we see is the color that is deflected from the RGBHSB.etc. This means that the light has all the colors within, and the object it hits absorbs all but one color, in which it deflects for our eyes to see.

Answer:
The balloon expands in the number of particles per cubic centimeter decreases. This happens because as it expands there is a decrease in the density of area. The Dead Sea is a solution that is so dense that you easily float on it.
