How do you calculate the age of a rock? Where size, width, and peak are the scale of the gestational sac, all in the identical models. Zsa Zsa said that a younger woman ought to marry a man who’s in his 40s. She, then at her sexual peak, ought to marry a man who is 18, n...
The account’s value will be $101 after one year, due to the interest. Knowing this, we can calculate the growth constant. N(t) = A e(kt) 101 = 100 e(k * 1 year) ln(1.01) = (1 year) * k k = 0.00995 /years To find the value of the account at ten years, t = 10. ...
To make a finer point on their brushes, the girls would lick them. Sometimes to break up the monotony, the girls would paint their teeth and lips and turn off the lights. Although managers regularly tested the girls for radioactivity, the women never received the results of these tests. In...

As a rough rule of thumb, you can calculate the temperature at any altitude by subtracting 3.5F (or 2C) for every 1000 feet of altitude above sea level. (This is known as the lapse rate). So in general, the temperature at 30,000 feet is 105F of 60C below the ground temperature. ...
On testing the ore known as pitchblende, Marie Curie discovered that it produced more than four times the radioactivity that was expected from the uranium it contained. She correctly deduced that this must be due to another radioactive element contained within. In the coming months, the Curies ...
In how much is the quantity of the isotope reduce to 25% of the original amount? View Solution The half-life period of a radioactive element is 1.4×1010 years. Calculate the time in which the activity of the element is reduced to 90% of its original value. View Solution...
