Suppose there is a mineral body which contained some amount of superscript 238 baseline upper u, which has a half-life of 4.51 times 10 superscript 9 years, but has no lead, the end product of the radioactive decay of superscript 238 baseline upper u. if the ratio of superscript 238 baseline upper u to lead atoms today is 0.42, how long ago did the mineral body form?

lol for the pointsss

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .

the pseudoscience are like beliefs, theories, or like practices that are considered scientific
