You have just isolated a new radioactive element. If you can determine its half-life, you will win the Nobel Prize in physics. Y
Troyanec [42]
Staals half
1 gram left
0.3 grams left
half lives are normally written in years
it goes likt this

A=P( \frac{1}{2})^ \frac{t}{h}
A=final amount
P=initila amount
t=time elapsed
h=time half life is (same units as time)

let's use days as the units of time


we are given
initial amount=1gram
final amount=0.3gram
time=4 days

so
0.3=1( \frac{1}{2})^ \frac{4}{h}
solve for h
0.3=( \frac{1}{2})^ \frac{4}{h}
take the ln of both sides
ln(0.3)=ln( \frac{1}{2})^ \frac{4}{h}
ln(0.3)=\frac{4}{h}ln( \frac{1}{2})
times both sides by h
hln(0.3)=4ln( \frac{1}{2})
divide both sides by ln(0.3)
h= \frac{4ln( \frac{1}{2}) }{ln(0.3)}
use calculator
h=2.30287
3 sig figs
h=2.303 days

Prism A is similar to Prism B. The volume of Prism A is 2720 cm³.
ZanzabumX [31]

Note that  the scale factor of B to A  is  (4 / 8)  =  1/2

So....the volume of B  =

Volume of A  *  (scale factor)^3  =

2720  *  (1/2)^3  =

2720 * 1/8  =
