U=mgh
U=10*9.8*20
U=1960
Answer is D
Farenheit is the best to measure accurate temperature because, It can go into the negatives(-) and unlimited positives(+). Celcius(C) only goes from 0-100°C Stating that water freezes at 0°C and Boils at 100°C. Farenheit has unlimited temperatures because as time goes by we continue making new discoveries in science.
I Hope This Helps!!! :)
Answer:
No
Explanation:
Acceleration = Velocity/Time
An example of where the velocity would be different is:
Acceleration = (automobile 1)
Acceleration = (automobile 2)
As you can see, the velocity for the first automobile is 10 m/s while the second one has a velocity of 25 m/s (with a greater time travelled) and both resulted in the same acceleration of 5 m/s².
Answer:
the second time there is a gas between you and the star,
Explanation:
When you observe the star for the first time you do not have a given between you and the star, therefore you observe the emission spectrum of the same that is formed by lines of different intensity and position that indicate the type and percentage of the atoms that make up the star.
When you observe the same phenomenon for the second time there is a gas between you and the star, this gas absorbs the wavelengths of the star that has the same energies and the atomisms and molecular gas, therefore these lines are not observed by seeing a series of dark bands,
The information obtained from the two spectra is the same, the type of atoms that make up the star
