The worker that is Most likely to be paid at the legal minimum wage rate would be letter D. This is because the person has a highschool diploma but he or she did not continue to college so he or she does not specialize or train for the work he or she will be applying for. So he or she must have the minimum wage.
Answer:
1. Letter A indicates the crest.
2. Letter E indicates the wavelength.
3. Letter C indicates the trough.
Explanation:
1. Determination of the the crest.
A crest is simply defined as a point on a wave where the displacement is maximum (i.e highest).
Considering the diagram given above, the point where the displacement is maximum is A. Therefore, A is the crest of the wave.
2. Determination of the wavelength.
The wavelength of a wave is simply defined as the distance between two successive crest or trough.
Obeserving the diagram above, we can see that E gives the distance between two successive crest. Therefore, E is the wavelength of the wave.
3. Determination of the trough.
A trough is simply defined as a point on a wave where the displacement is minimum (i.e lowest). Thus we can say that the trough is the opposite of the crest.
Considering the diagram given above, the point where the displacement is minimum is C. Therefore, C is the trough of the wave.
Answer:
The ratio of gravitational force is 0.8920
Explanation:
The gravitational force is given by F=![\frac{GMm}{R^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BGMm%7D%7BR%5E%7B2%7D%20%7D)
The gravitational force on the astronaut when he is in
Surface of earth F₁ =
eqn 1
Circular orbit F₂ =
eqn 2
Where M is mass of earth,
m is mass of astronaut
R is radius of earth 6380 km,
h is the distance from earth surface 315 km.
Dividing eqn 1 and 2
= ![\frac{R^{2} }{(R+h)^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BR%5E%7B2%7D%20%7D%7B%28R%2Bh%29%5E%7B2%7D%20%7D)
=
=0.8920
The ratio of gravitational force is 0.8920
