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>
B. $0.35
since to find the unit rate of one candy bar, you have to divide $350 by 1000 and you get $0.35
the rate is 350/1000 = 0.35/1
Answer:
It may be 71.78 cm square
5=100%
5/100=0.05=1%
7.5/0.05=150%
Answer: +50%
First solve to your equation by step by step.
1/5(2x-10)+4x=-3(1/5x+4)
= x=-2
Answer is x=-2
It will help you.
