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.

Explanation:
1 billion years after the big bang, the temperature is 20K and some stars and galaxies began to contract due to the gravitational contraction of the over densities of the previous universe. At about 10 billion years after the big bang, our earth and sun form
"B" When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer.
Answer:
Explanation:
Mass of object = m
Height above planet = h
Mass of planet = M
Radius of planet = R
As we have to find out velocity, so let's apply the law of conservation of energies on initial( when the object was at height) and final( when object hit the surface points.
Initial energy = Final energy
