Answer:

2 more neutrons

Explanation:

To obtain the answer to the question, let us calculate the number of neutrons in carbon–14 and standard carbon (i.e carbon–12). This can be obtained as follow:

For carbon–14:

Mass number = 14

Proton number = 6

Neutron number =?

Mass number = Proton + Neutron

14 = 6 + Neutron

Collect like terms

14 – 6 = Neutron

8 = Neutron

Neutron number = 8

For carbon–12:

Mass number = 12

Proton number = 6

Neutron number =?

Mass number = Proton + Neutron

12 = 6 + Neutron

Collect like terms

12 – 6 = Neutron

6 = Neutron

Neutron number = 6

SUMMARY:

Neutron number of carbon–14 = 8

Neutron number of carbon–12 = 6

Finally, we shall determine the difference in the neutron number. This can be obtained as follow:

Neutron number of carbon–14 = 8

Neutron number of carbon–12 = 6

Difference =?

Difference = (Neutron number of carbon–14) – (Neutron number of carbon–12)

Difference = 8 – 6

Difference = 2

Therefore, carbon–14 has 2 more neutrons than standard carbon (i.e carbon–12)

Considering only the earth's rotation, determine how much later the asteroid would have had to arrive to put the explosion above
tangare [24]

Answer:

5.1 hours

Explanation:

The only fact we need to know about such a question is that when gazing down at the north pole, the earth spins longitudinally at 360 degrees / day in the clockwise direction.

The planet would have to spin an additional 77 ° to strike the asteroid at 25° E. If the earth rotates in 24 hours 360 degrees, then it must it rotates in 5.1 h at 77 degrees.

Vitek1552 [10]
Base on your question where as a mass m is 15kg is pulled along a horizontal floor, with a coefficient of kinetic friction 0.06 and for a distance of D = 8.5 so the ask of the problem is to calculate the work done by tension before the bock. <span>Base on my calculation and through step by step procedure and with the guidance of the theories and by the use of formulas, I came up with an answer of 313 joules. </span>

In the form of radioactive decay known as alpha decay, an unstable nucleus emits a helium-atom nucleus, which is called an alpha
trapecia [35]

Answer:

Velocity will be v=4.06\times10^7m/sec

Explanation:

We have given mass of alpha particle m = 4 u =4\times 1.67\times 10^{-27}kg=6.68\times 10^{-27}kg

Charge on alpha particle q=2e=2\times 1.6\times 10^{-19}C=3.2\times 10^{-19}C

Charge on thorium particle =90\times 1.6\times 10^{-19}=144\times 10^{-19}C

Diameter is given as d = 15 fm

So radius r=\frac{d}{2}=\frac{15}{2}=7.5fm=7.5\times 10^{-15}m

Potential energy is given by E=\frac{1}{4\pi \epsilon _0}\frac{q_1q_2}{r}=\frac{Kq_1q_2}{r}=\frac{9\times 10^9\times 144\times 10^{-19}\times 3.2\times 10^{-19}}{7.5\times 10^{-15}}=5.529\times 10^{-12}J

From energy conservation \frac{1}{2}mv^2=5.529\times 10^{-12}

\frac{1}{2}\times 6.68\times 10^{-27}v^2=5.529\times 10^{-12}

v=4.06\times10^7m/sec

An electron shell can hold 2(n^2) electrons (technically) where n is the shell number, i.e. shell 1 can hold 2, shell 2 can hold 8, 3 holds 18 and so on.
The atomic number of Nitrogen is 7, i.e. it has 7 electrons (to match its 7 protons, assuming it isn't an ion).

With the atomic number, you simply start from shell 1 and work out. So we put 2 electrons in shell 1, leaving us with 5 left. Shell 2 can hold 6 so we can fit all 5 in.

In other words, you should have 2 electron shells on the atom, shell 1 with 2 e- and shell 2 with 5 e-.
