Answer:
I'M SORRY I CAN'T SEE THE PICTURE BUT IT WILL MOST LIKELY BE THE DIFFERENCE BETWEEN THE NUMBERS
Explanation:
for instance if there was someone pushing a desk with a net force of 9 towards the right, the net force would come to a total of 9 since there is no one on the other side pushing the desk. Meaning the desk would go right. I'm sorry if this isn't what you needed D:
Answer:
23.64 m
Explanation:
Potential energy is given by
PE=mgh
Where m us the mass of snowball, g is acceleration due to gravity, h is height.
Also, the weight of an object is given by W=mg hence replacing mg in the above equation with W we obtain
PE=Wh
Making h the subject of the formula then
Substituting 520 J for PE and 22 N for W then
<h2>
All of these</h2>

Answer:
Explanation:
Given that,
The half-life of Barium-139 is
A sample contains nuclei.
We need to find the decay constant for this decay. The formula for half life is given by :
Put all the values,
So, the decay constant is .
