Answer: I would say static electricity.
Explanation:
Answer:
frequency of the first tuning fork can be 274 Hz or 266 Hz
Explanation:
Given data :
we have number of beats per second = 4
thus, it can also be written as
Beat frequency of the tuning fork, v = 4 Hz
Frequency of the tuning fork, f = 270 Hz
now, the beat frequency is actually the difference of the consecutive frequency.
thus, we have
Frequency of the first tuning fork as = 270 Hz + 4 Hz = 274 Hz
or
Frequency of the first tuning fork as = 270 Hz - 4 Hz = 266 Hz
Therefore, the frequency of the first tuning fork can be 274 Hz or 266 Hz
The existence of photosynthetic organisms, particularly the blue-green algae, are the organisms responsible for changing the early atmosphere of the Earth. These organisms came from rock formations found throughout Earth and are responsible for feeding off on the carbon dioxide that was abundant in its atmosphere. As they have learned to feed-off carbon dioxide, they in turn have transformed this compound and produced oxygen.
Scientists have also proven that rocks and other sediments contained abundant amounts of trapped oxygen. Through time when the rocks have withered and formed into sediments these oxygen gases are released into the air and got trapped within the atmosphere overpowering the levels of carbon dioxide.
This phenomenon is very important throughout the history of Earth because the Earth became a habitable planet where several species can thrive. This phenomenon has also led to the several geographical changes that the Earth has undergone to because it cooled-down its overall temperature.
Answer:
Price=$7×10⁷
Explanation:
Step 1: Estimate the volume of the pile,
Step 2: Multiply it by the density to get its mass
Step 2: Then multiply the mass by the price per gram to get the total price
So
The average pile dimensions are=45.7×45×172.7
Price=m×$10
Price=(7×10⁶)×$10
Price=$7×10⁷
