The equation to use is v=fλ where v is the speed of light, f is the frequency, i.e. the rate at which they vibrate, and λ is the wavelength in meters.
Rearrange the above equation and you get f=v/λ. So the answer is f=300000000/0.001 or 300GHz.
The potential energy is 6 joules
Gravity is equal to 9.8 m/s
The height from where it is from is 3 meters
The mass = 6/(9.8 x 3) =
6/(29.40) = 0.204 kg!
Longer I took a little physics but I remember them saying that a small star lasts longer than a larger star
Knowing the distance may only give you the relative locations between two points, but not the exact location. So, the answer to his question is no. Knowing the distance does not give enough information. If perhaps the coordinates of both points were given, then that would be considered enough information.
When practicing an oral presentation, you can prepare by writing a draft and practice reading aloud what you are going to say before your oral presentation.
