Remember
(ab)/(cd)=(a/c)(b/d)
and
1kg=1000g=1*10^3g
hmm, I estimate, 4 of them
x=number of attoms
mass of 1 times x=1*10^3
3.95*10^-22 times x=1*10^3
divide both sides by 3.95*10^-22
x=
=
=
a million has 9 zeroes
so 24 zeroes is alot that is a <span>septillion, so there are 2.5316 septillion uranium atoms in 1kg
a. 4
b. underestimate

The quadratic model is f(x) = -5x^2 + 200.
f(x) = 50 meters
x = time in seconds
50 = -5x^2 + 200
5x^2 = 150 // Here, divide both side by 5
x^2 = 30
x =
seconds
Or approximately 5.48 seconds
