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>
Answer:
37/200
Step-by-step explanation:
Event/Sample Space = .185 = 18.5%
Answer: It’s c
Step-by-step explanation:
Answer:
There are 52 possible outcomes when you draw one card from a standard deck. Hence, 52 is the denominator of your probability fraction.
Parallel lines have the same slope. So if a line has a slope of 2, a line parallel to it also has a slope of 2.
