<span>We are given the initial amount of 1 million carbon-14 atoms and the final amount which is 1/16 of the current atmospheric 14C levels. Also, the half life of carbon is </span>5,750 years. WE can use the decay formula
Aₓ = A₀e^-(ln2/t1/2)t
1,000,000(1/16) = (1,000,000)e^-(ln2/5750)t
t = 23,000 years
Answer:
The answer to your question is The honda civic hybrid weights 13181.8 N or 1318.2 kg
Explanation:
Data
Weight = 2900 lb
Weight = ? N
mass = ? kg
1 kg ------- 10 N
0.22lb ---- 1N
Use proportions to solve this problem
0.22 lb ------------------- 1 N
2900 lb ----------------- x
x = (2900 x 1) / 0.22
x = 2900 / 0.22
x = 13181.8 N
1 kg ----------------------- 10 N
x ----------------------- 13181.8 N
x = (13181.8 x 1)/10
x = 1318.2 kg
He used that name because if you lit hydrogen on fire it would catch. therefore, it was dangerous to be around. think of it as a kind of warning. :) hope that helps.
Answer:
N, O, R
Explanation:
Thanks for answering bro, you saved me
They should identify the confounding variable.
Some condition that is not examined by the scientist might alter the experiment result. That condition is called confounding variable. If the method of the experiment same but result is very different, there should be unidentified confounding variable. It could be air humidity, temperature, ventilation, light, time of the year or anything that might not be seen by naked eye.
Try to redo the experiment with controlling variable as much as possible.
