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:
a is x>3
b is _> x/4 +12
c is x>-3
Step-by-step explanation: hope this helps
Answer:1/3
its 1/3 because 4 dived by 4 = 1 and 12 dived by 4 =3 so answer is 1/3
No, a & b are not independent if they're mutually exclusive.
Mutually exclusive means the two events cannot occur simultaneously. So if "a" happens "b" cannot. In contrast, two events are independent if the occurrence of one has no effect on the occurrence of the other.
Answer:
d
Step-by-step explanation:
given that your slop is -4/3, plug the (x,y) point in to the equation of y = -4x/3 +b
-1 = -4 + b , b = 3
y = -4x/3 + 3
