The people use Earth's motion to determine units of time because of its uniform motion which is consistent.
<u>Explanation:</u>
In earlier days, people used to observe the motion of Earth to measure time. This is because, the Earth is moving at constant speed and at constant acceleration. So the change in position of the sun or stars can be easily correlated to the time.
Due to the consistency in the Earth's motion and the accurate repetition of the time period along with the seasons, the Earth's motion can be considered as a responsible source to determine the units of time.
2AgBr+Cl2=2AgCl+Br2
You want everything to be the same on both sides the easiest way to do that is draw a line down the equal sign and write out all you compound and how many there are and do the same on the other side until there even
Answer:
Sound waves travelling through the air: Sound waves travelling through air are just like longitudinal waves lacking compressions and rarefactions. The speed of sound waves in air is approximately 332 metres per second.
Light waves travelling through air: Light waves travel in air at a much faster rate than sound waves. Light waves can travel with a speed of 300 000 kilometres per second through air.
Sound waves traveling through metal: Sound waves travel about 17 times faster in metal as compared to air. The sound waves travel with an approximate speed of 5,960 meters per second in metals.
Light waves travelling through metal: The speed of light waves in a metal medium is usually at a net speed which is less than 3.00 x 108 m/s.
Light travels faster than sound waves because light waves are not pressure waves like the sound waves. They also do not require a medium as the sound waves.
Research and new advancements in discoveries like fingerprint unlock for phones.And 3d printers.They were made by researching and discovering new things.
14040/4=3510 wheels per 4 nuts
3510/4=877.5 cars per 4 wheels
877 possible cars.
actual yield 850/theortical yield 877=96.92%
