Problem: An unstable atomic nucleus of mass 1.60 10-26 kg initially at rest disintegrates into three particles. One of the particles, of mass 5.08 10-27 kg, moves along the y-axis with a speed of 6.00 106 m/s. Another particle, of mass 8.50 10-27 kg, moves along the x-axis with a speed of...
I have used up two more of my answers on:
8 and -8 it gave me this error
"Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize...

All of this was very helpful. I did the math on my own and my answer matched yours. I went to enter it in and this is what I got.
Attempt 1:
(c) Find the number of balls (order of magnitude only)
1.56e6 Balls
Your response differs from the correct answer by 10% to 100%.
Attempt 2: (I...
This was a lot of help. When I got to the end I got +- (7.48331). When I inputed +- (7.5) as the answer it marked it wrong. What should the answer be if this is incorrect?
