What do the astrometric, doppler, and transit methods share in common? a. what do the astrometric, doppler, and transit methods share in common? b. they all allow us to measure a planet's size (radius). c. they all search for planets by measuring properties of a star rather than of the planets themselves. d. they all require very high-resolution imaging. e. they all require high-resolution spectroscopy. f. all of the above.

Astrometric, Doppler, and transit methods share in common as they all search for planets by measuring properties of a star rather than of the planets themselves.

Option C

Explanation:

Astronomers always try to discover new planets and galaxies. They employ various methods for finding new planets which include astrometric, transit and Doppler method. All these methods have one common aspect in their approach for finding new planets is that they measure the properties of star instead of planets.

Planets are smaller compare to its parent stars. Therefore, it is difficult to detect light from planets as the light of their parent star washes out the light of planet hence making it difficult to detect the planets.

marginal cost is a microeconomic measure that us to evaluate the extent to which the level of production of a good is sustainable in accounting, that is, to how many quantities the company plans to profit from the production of the good.

the concept of marginal cost is simple, it means the cost of producing one more item. for example, in the case of pies, the marginal cost is the cost of producing one more pie than those that have already been produced.

it is important to understand that productive activity influences marginal cost. the marginal cost of some goods can be very high, while others may be insignificant. for example, the marginal cost of producing an extra plane is very high. already the marginal cost of a water company to provide 1l more water is derisory.

in the case of pies, the cost involves the inputs, the labor and the fixed cost, which involves the fixed space of the bakery. the level of production initially has the marginal cost decreasing because there is space and manpower available. however, to produce more you have to hire more workers and buy more inputs. if physical space is limited, workers will conflict with places, inputs and their productivity will decrease, meaning there is an optimum point of production for each level of space and manpower. from this point on, the productivity of the workers will be getting smaller because of lack of space, so that the marginal cost of producing one more pie will be increasing. so, although you have not posted the chart, but if you have the answer, you can see that my explanation goes according to the marginal cost curve that will increase from the 4th pie, answer (c).
