Answer:
1 750 g
Step-by-step explanation:
hhhahahahahahahaha
It could be 10.11 10.12 10.13 10.14
as long as the number next to the one is less than five it will become 10.1
For the answer to the question above,
<span>a) Use F = k * q1 * q2 / d²
where k = 8.99e9 N·m²/C²
and q1 = -1.602e-19 C (electron)
and q2 = 1.602e-19 C (proton)
and d = distance between point charges = 0.53e-10 m
The negative result indicates "attraction".
b) Here, just use F = ma
where F was found above, and
m = mass of electron = 9.11e-31kg, if memory serves
a = radial acceleration
c) Now use a = v² / r
where a was found above
and r was given
d) period T = 2π / ω = 2πr / v
where v was found above
and r was given </span>
Yes, you are correct, because -2 is 2 spaces away from the number line.
16/21 is the correct answer
