What is one of Kepler's laws of planetary motion?

Physics

VikaD [51]3 years ago
4 0

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

\frac{T^2}{r^3} = const.

and the constant in the equation has the same value for every planet orbiting around the Sun.

5. Find the mass of a car that is traveling at a velocity of 35 m/s West.
sattari [20]

Answer:

m = 9795.9 kg

Explanation:

v = 35 m/s

KE = 6,000,000 J

Plug those values into the following equation:

KE = \frac{1}{2} mv^{2}

6,000,000 J = (1/2)(35^2)m

---> m = 9795.9 kg

What would happen if you tried to use a prism to disperse a beam that contained only green light?​
Margaret [11]

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
