What is one of Kepler's laws of planetary motion?
1 answer:
The Kepler laws of planetary motion are:
1) The planets revolve around the Sun following elliptical orbits, in which the Sun occupies one of the two focii
2) A line segment connecting the Sun with the center of each planet sweeps out equal areas in equal intervals of time --> this means that the speed of the planet changes according to its distance from the Sun: the closer to the Sun, the faster the planet
3) The square of the orbital period of the planets is proportional to the cube of the semi-major axis of the orbit. In formula
and the constant in the equation has the same value for every planet orbiting around the Sun.

Answer:
m = 9795.9 kg
Explanation:
v = 35 m/s
KE = 6,000,000 J
Plug those values into the following equation:
6,000,000 J = (1/2)(35^2)m
---> m = 9795.9 kg
Answer: attached
Explanation:
It is determined by the nature of the green light. Because lasers create light at almost a single frequency, green laser light would appear as a thin line of pure green. Other sources of "green" light emit light at a variety of frequencies, including yellow and blue, resulting in a strong green band in the center that fades into blue-green and yellow-green at the borders.
For example, here’s a graph of the spectrum of a green LED, showing the color range: Attachment #1
and here’s a graph of the transmission spectra of several standard photographic filters, including green: Attachment #2
