Ans: Radiocarbon dating uses carbon isotopes.
Radiocarbon dating relies on the carbon isotopes carbon-14 and carbon-12. Scientists are looking for the ratio of those two isotopes in a sample. Most carbon on Earth exists as the very stable isotope carbon-12, with a very small amount as carbon-13.
Answer:
Your answer is B.!
When things in general get hotter, the atoms inside move faster and vise versa with cold.
(for example water); if you put water in a pot on a stove to boil, its gets so hot to where the atoms are moving really fast to get it to look like that.
Please mark brainiest! if this answer is wrong, (which I'm pretty sure it isn't) then pick D. :D
Answer:
R = 620.0 Ω +/- 5%
Explanation:
According to the standard color coding for carbon resistors, the first color represents the first digit, the second the second digit, the third is the multiplier factor (10*x), and the fourth (if existing) defines the tolerance.
In our case, we have:
Blue = 1st digit = 6
Red = 2nd digit = 2
Brown = Multiplier = 10*1 = 10
Gold = Tolerance = +/- 5%
⇒ R = 62*10 = 620.0 Ω
Tolerance = +/- 5%
Because lighter coloured backgrounds make our brain think that the text in the darker colour is bigger and bolder.
By conservation of momentum :
By conservation of energy :
Solving equation 1 and 2, we get :
v = 1.23 m/s
Therefore, the initial speed of 96 kg car is 1.23 m/s .
