What is the charge value of 45 electrons

Physics
1 answer:
tamaranim1 [39]3 years ago
8 0

Answer:

7.2\times 10^{-18}C

Explanation:

-Let x be the charge of 45 electrons

-An electron has a relatively law mas.

-Using the law of proportions, the charge value of 45 electrons is calculated as:

1e=1.6 \times 10^{-19} coulomb\\45e=x\\\\x=\frac{45\times1.6 \times 10^{-19} coulomb}{1e}\\\\x=7.2\times 10^{-18}C

Hence, the electron charge of 45 electrons is 7.2\times 10^{-18}C

What distance is required for a train to stop if its initial velocity is 23 m/s and its
Varvara68 [4.7K]

-- The train starts at 23 m/s and slows down by 0.25 m/s every second.

So it'll take (23/0.25) = 92 seconds to stop.

-- Its average speed during that time will be (1/2)(23+0) = 11.5 m/s

-- Moving at an average speed of 11.5 m/s for 92 sec, the train will cover

(11.5 m/s) x (92 sec)  =  <em>1,058 meters</em> .

An oxygen atom picks up two additional, free-floating electrons. Is the charge of the newly formed oxygen ion positive, negative
MariettaO [177]

Answer: Negative

Explanation:

An oxygen atom has the chemical symbol O. Its atomic number is 8, with an electronic configuration of 1s2, 2s2 2p4.

Now, due to the incompletely filled p-orbital, oxygen picks up two additional, free-floating electrons (2e-) to complete its outermost shell. And since each electrons received carries a negative charge, oxygen atom becomes a negatively charged divalent ion, O2-

See the equation below

O + 2e- ---> O2-

tekilochka [14]

Answer:

i believe the answer is d.

Explanation:

its either d or its c. but based off of the fact the it is the only one with a positive charge and the one around it are negative then its most likely d.
