Answer:
The answer to your question is the letter A) F = 9.23 x 10⁻⁷ N
Explanation:
Data
q₁ = -6.25 x 10⁻⁹ C
q₂ = -6.25 x 10⁻⁹ C
d = 0.617 m
k = 9 x 10⁹ Nm²/C²
F = ?
Formula
F = k q₁q₂ /r²
-Substitution
F = (9 x 10⁹)(-6.25 x 10⁻⁹)(-6.25 x 10⁻⁹) / (0.617)²
-Simplification
F = 3.512 x 10⁻⁷ / 0.381
-Result
F = 9.227 x 10⁻⁷ N ≈ 9.23 x 10⁻⁷ N
-- If the field were inclined to the surface, then it would have
some component parallel to the surface.
-- Then, since we're talking about a conductor, the charges
on the object would move in response to that component
of the field, until there was no longer any component of the
field trying to move them.
I think it would be the scientific method.
Answer:
Potential energy. Releasing it, the potential energy would convert into motion, kinetic energy.
Potential energy is when an object has some sort of potential eg. for motion such as in this example.
Based on the formula for calculating impulse, the impulse of the speed bump to the car is 2500 Ns.
<h3>
What is the impulse of the speed bump?</h3>
- Impulse = change in momentum
- momentum = mass * velocity
Change in momentum = mu - mv
where u is initial velocity
v is final velocity
Impulse = 500 * 20 - 500 * 15
Impulse = 2500 Ns
Therefore, the impulse of the speed bump to the car is 2500 Ns.
