In the following image, what conclusion can you draw about the speed of the planet at location A compared to location B? (2 poin

ts)
A diagram showing the orbit of a planet around the sun. When the planet moves through the part of its orbit labeled A, it is closer to the sun than it is when it moves through the part of its orbit labeled B.

When the planet is at A it is moving faster than at B.

When the planet is at A it is moving slower than at B.

There is no change in speed for the planet at either A or B.

The orbital speed of the planet is the square of the distance between A and B.

The answer is; When the planet is at A it is moving faster than at B.

This is because when the planet is closer to the sun at point A, it is experiencing a stronger gravitation, by the sun, pull than at point B. Therefore, its acceleration due to gravity at point A is higher than at point B.

Answer:

When the planet is at A it is moving faster than at B.

Explanation:

<u>From Kepler's second law,</u> the line joining planet to the star sweeps equal area in equal amount of time. This decides the speed of the planet at different locations in its elliptical orbit around the star. The position closer to the star (At A) the speed would be greater as compared to the position away from the star (At B) in accordance with the law.

In a certain species of plant, the allele to produce green melons (G) is dominant over the allele to produce yellow melons (g).
marishachu [46]

Answer:

4.26

Explanation:

Let the green-melon parents be Gg, then we expect the cross with the yellow-melon plant gg so as to produce 50% Gg and other 50% of gg offspring. What we observed was that 53 green and a 41 yellow. Based on the total number of 94 offspring , we expected half and a half ratios to be 47 of each color.

                                Observed(o)   Expected(e)   (o-e)    $(o-e)^2$      $(o-e)^2/e$

Green-melon plant        53                    47               6          36             0.766

Yellow-melon plant        41                    47              -6          36             0.766

Therefore the chi-square value is 1.53 which is less than the critical value of 3.84. Therefore, the null hypothesis is accepted.
