Let FAB, be the force exerted on body B by body A and FBA be the force exerted by body B on A. Suppose that due to these forces FAB and FBA, dp1/dt and dp2/dt be the rate of the change of momentum of these bodies respectively.
Answer:
3 Cycles
Explanation:
Every cycle on a cosine function are marked by the completion of 5 key points when moving along the x-axis:
(5, 0, -5, 0, 5)
This cycle has a frequency of 2, occurring once every second, thus answering our question easily.
The answer is that they both have rings.
Saturn has a tilted axis of 26.73 degrees and Uranus is tilted by 98 degrees.
Only two of eight planets rotate backwards, which are Venus and Uranus.
Saturn has more than a dozen rings and Uranus has 9 bright rings as well as several fainter rings.
Saturn and Uranus are outer planet meaning it is found outside the asteroid belt.
The frequency of sodium light in vacuum is 5 × Hz.
Answer:
Option e
Explanation:
It is known that frequency of a wave is inversely proportional to the wavelength of the wave. And the proportionality constant is the speed of light in vacuum. As the speed of light in vacuum is known as 3× m/s and the wavelength of the light in vacuum is given as 6 × m, then the frequency of the light is determined as
Frequency = Speed of light in vacuum/Wavelength of light
Frequency =
Frequency = 0.5× = 5 × Hz.
So the frequency of sodium light in vacuum is 5 × Hz.
I am not 100% sure but i would say D, since it is a smaller object than the test thus needing a shorter wavelength
