In,radioactive decay,the half-life is the length of time after which there is a 50 percent chance that an atom will have undergone nuclear decay.It varies depending on the atom type and isotope,and is usually determined experimentally.
<span>L = m r X v ................this is the cross product of two vectors r and v
L = mvr sin(angle) = (2)(12)(8)sin(143.1degrees) = 115.28 kgm^2/s

b)greater
c) greater
d) force*distance
e)Nm
Answer:
hello
Explanation:
for average speed the total distance is important so.
and you must convert min to hour 15 min is 1/4 or 0.25 hour

for average velocity the straight line distance is important so

hope you understand
Given:
Sample 1:
Chloroform is 
12 g Carbon
1.01 g Hydrogen
106.4 g Cl
Sample 2:
30.0 g of Carbon
Solution:
mass of chloroform from sample 1:
12 + 1.01 +106.4 =119.41 g
Now, for the total mass of chloroform in sample 2:
mass of chloroform 

mass of chloroform = 119.41 
= 298.53 g
