Answer:
<u>b. 2.27 N</u>
Explanation:
Fe = (k)(Q1)(Q2) / d²
k ≈ 9 × 10⁹ N m² / C² [Coulomb's Constant] or 8.98 × 10⁹ (nearest hundredth).
q = particle charge [Coulombs; C]
d = distance [Meters; m]
Fe = Electrostatic force [Newtons; N]
________________________________
Fe = (9×10⁹)(3.5 × 10^(-8)(-4.5 × 10^(-6))/(.25)² N =
(9)(3.5)(-4.5) × (10^(9))(10^(-8))(10^(-6) / (.25)² N =
(9)(3.5)(-4.5) × (10^(9 - 8 - 6)) / (.25)² N =
(-141.75) × 10^(-5) / (.0625) N =
141.75 × 10^(-5) / (.0625) N
[opposite direction] =
(1.4175 × 10^(2)) × 10^(-5) / (.0625) N
[opposite direction] =
1.4175 × 10^(-3) / .0625 N
[opposite direction] =
1.4175 × 10^(-3) / 6.25 × 10^(-2) N =
14.175 / 6.25 N [opposite direction] =
2.268 N ≈ 2.27 N [opposite direction].
02 is oxygen gas , having 2 particles of O, whereas F2 is Fluorine gas having two particles of F.
Answer:
Momentum of bullet
momentum of baseball
Explanation:
As we know that momentum is defined as the product of mass and velocity
here we know that
mass of the bullet = 8 gram
velocity of bullet = 340 m/s
momentum of the bullet is given as
Now we have
mass of baseball = 0.2 kg
velocity of baseball = 40 m/s[/tex]
momentum of baseball is given as
