<span>uclear Physicist specializing inoffensive weapons systems - pretty obvious why this would be.
Highway Engineer - again, pretty obvious reasons.</span>
I'm pretty sure that the only right answer is <span>B) a north-seeking pole of unit strength with a south-seeking pole of the same strength. Because there are no single magnetic poles.</span>
Answer:
10 seconds
Explanation:
We can calculate the average speed by finding the total distance traveled divided by the elapsed time: Average speed=–s=Total distance Elapsed time
Answer: the correct answer is 7.8026035971 x 10^(-13) joule
Explanation:
Use Energy Conservation. By ``alpha decay converts'', we mean that the parent particle turns into an alpha particle and daughter particles. Adding the mass of the alpha and daughter radon, we get
m = 4.00260 u + 222.01757 u = 226.02017 u .
The parent had a mass of 226.02540 u, so clearly some mass has gone somewhere. The amount of the missing mass is
Delta m = 226.02540 u - 226.02017 u = 0.00523 u ,
which is equivalent to an energy change of
Delta E = (0.00523 u)*(931.5MeV/1u)
Delta E = 4.87 MeV
Converting 4.87 MeV to Joules
1 joule [J] = 6241506363094 mega-electrón voltio [MeV]
4 mega-electrón voltio = 6.40870932 x 10^(-13) joule
4.87 mega-electrón voltio = 7.8026035971 x 10^(-13) joule
You measure the total distance the bike travels, and the total time it takes to travel that distance. You then divide the distance by the time
