Answer:
The mass number is the product of number of protons and number of neutrons
The atomic number is the same as the mass number but just put amu next to the number
Answer:
The path separation is 0.10 m
Solution:
As per the question:
Mass of
, m = ![2.66\times 10^{- 26}\ kg](https://tex.z-dn.net/?f=2.66%5Ctimes%2010%5E%7B-%2026%7D%5C%20kg)
Ratio of the masses, R = 16:18
Velocity, v = ![4.9\times 10^{6}\ m/s](https://tex.z-dn.net/?f=4.9%5Ctimes%2010%5E%7B6%7D%5C%20m%2Fs)
Magnetic field, B = 1.05 T
Now,
Mass of
, m' = m\frac{1}{R} = 2.66\times 10^{- 26}\times \frac{18}{16} = 2.99\times 10^{- 26}\ kg[/tex]
Now, centripetal force here is provided by the magnetic force on the charge 'q' and is given by:
![\frac{mv^{2}}{r} = qvB](https://tex.z-dn.net/?f=%5Cfrac%7Bmv%5E%7B2%7D%7D%7Br%7D%20%3D%20qvB)
![r = \frac{mv}{qB}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7Bmv%7D%7BqB%7D)
Now, for
:
![r = \frac{2.66\times 10^{- 26}\times 4.9\times 10^{6}}{1.6\times 10^{- 19}\times 1.05} = 0.77\ m](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B2.66%5Ctimes%2010%5E%7B-%2026%7D%5Ctimes%204.9%5Ctimes%2010%5E%7B6%7D%7D%7B1.6%5Ctimes%2010%5E%7B-%2019%7D%5Ctimes%201.05%7D%20%3D%200.77%5C%20m)
Now, for
:
![r' = \frac{m'v}{qB}](https://tex.z-dn.net/?f=r%27%20%3D%20%5Cfrac%7Bm%27v%7D%7BqB%7D)
![r' = \frac{2.99\times 10^{- 26}\times 4.9\times 10^{6}}{1.6\times 10^{- 19}\times 1.05} = 0.87\ m](https://tex.z-dn.net/?f=r%27%20%3D%20%5Cfrac%7B2.99%5Ctimes%2010%5E%7B-%2026%7D%5Ctimes%204.9%5Ctimes%2010%5E%7B6%7D%7D%7B1.6%5Ctimes%2010%5E%7B-%2019%7D%5Ctimes%201.05%7D%20%3D%200.87%5C%20m)
Now, the separation distance of the path is given by:
![\Delat D = r' - r = 0.87 - 0.77 = 0.10\ m](https://tex.z-dn.net/?f=%5CDelat%20D%20%3D%20r%27%20-%20r%20%3D%200.87%20-%200.77%20%3D%200.10%5C%20m)
The temperature of the copper sample increases by ![172.9^{\circ}C](https://tex.z-dn.net/?f=172.9%5E%7B%5Ccirc%7DC)
Explanation:
When energy is supplied to a substance, the temperature of the substance increases according to the equation:
![\Delta T = \frac{Q}{m C_s}](https://tex.z-dn.net/?f=%5CDelta%20T%20%3D%20%5Cfrac%7BQ%7D%7Bm%20C_s%7D)
where
is the increase in temperature
Q is the amount of energy supplied
m is the mass of the substance
is the specific heat capacity of the substance
For the sample of copper in this problem,
m = 538.0 g
Q = 8373 cal
![C_s = 0.09 cal/gC](https://tex.z-dn.net/?f=C_s%20%3D%200.09%20cal%2FgC)
Therefore, substituting we have:
![\Delta T = \frac{8373}{(538.0)(0.09)}=172.9^{\circ}C](https://tex.z-dn.net/?f=%5CDelta%20T%20%3D%20%5Cfrac%7B8373%7D%7B%28538.0%29%280.09%29%7D%3D172.9%5E%7B%5Ccirc%7DC)

Answer:
Monitoring water quality is an important part of helping us determine whether or not we are making progress in cleaning up our waterways. It reveals the health and composition of streams, rivers, and lakes at a snapshot in time, as well as over weeks, months, and years. Dirty water could be dangerous to us, and our environment!
