Answer:
The age of the fossil be 
.
Explanation:
Formula used :
where,
= initial mass of isotope C-14 = x
N = mass of the parent isotope left after the time, (t) = 70.0% of x=0.07x
= half life of the isotope C-14 = 5730 years
= rate constant
Let the age of the fossil be t.
Now put all the given values in this formula, we get t :
The age of the fossil be .
False! The three states of matter are solid, liquid, and gas. We can not touch gas, so it can not be compressed.
Do DIMENSIONAL Analysis what comes up must come down
Explanation:
mass = desity × volume
volume = mass/density...
i believe thats right...
btw u means Physics formulae only..lol
Answer:
0.4 * 10^-12 m
Explanation:
Frequency of the given Electromagnetic radiation is 7.50* 10^20 Hz
Speed of the electromagnetic radiation is 3*10^8 m/s
Hence wavelength is given by the formula: Speed/Frequency
Substituting the required values:
Wavelength = 3 * 10^8/7.50 * 10^20
=3/7.5 * 10^-12 = 0.4 * 10^-12 m
Hence the required wavelength of the electromagnetic radiation is 0.4*10^-12 m/s
