Cutting and polishing exposed rock
Taking notes,because you can read back on what you learned
To solve this problem we will apply the Newtonian concept of gravitational acceleration produced by a planet. This relationship is given by:
Where,
G = Gravitational Universal Constant
M = Mass of Earth
r = Radius
The values given are based on the constants of the earth, so they can be expressed as
The relationship of gravity would then be given:
The relationship with the new planet, from the gravity of the earth would be given
The relationship with the weight of the earth would be given as:
Therefore the weigh on this planet would be 96N
Answer:
I'm not sure what your answer choices are but I would consider it a conductor.
Explanation: Things that conduct anything are conductors.
I hope that this will help, good luck.
Answer:
455.9 Hz, Flat
Explanation:
The beat frequency is basically the difference between the frequency of the B4 note and the frequency of the A4 tuning fork. This means the B4 note is 15.9 Hz off of 440Hz, and 67.4 Hz off of 525.3 Hz. As B4 is between the two notes, it would make sense to find its frequency by adding 15.9 to 440 and subtracting 67.4 from 523.3, both if which give us a frequency 455.9 Hz for the B4 key. This is because the note doesn't change for the different turning forks so both differences should result in the same frequency. Because the note should be 493.9 frequency but instead has a frequency of 455.9 Hz, it is flat because the frequency is lower than it is supposed to be.
Hope this helped!
