You rubbed two identical balloons in your hair's friend. This causes the balloons to become charged negatively with a magnitude

dem82 [27]

Answer:

a) F = 2.25 10³ N, b) REPULSIVE.

Explanation:

a) The electric force is given by coulomb's law

F = $k \frac{q_1q_2}{r^2}$ k q1q2 / r2

in this case nso indicate that the two charges have the same value

q₁ = q₂ = 2.5 10⁻⁶ C

Let's reduce the magnitudes to the SI system

r = 0.5 cm (1m / 100cm) = 5 10⁻³ m

let's calculate

F = $9 \ 10^9 \frac{(2.5 \ 10^{-6})^2 }{(5 \ 10^{-3})^2}$

F = 2.25 10³ N

b) In electricity, electric charges of the same sign repel and those of the opposite sign attract

In this exercise, the balls are equal and are rubbed with the same material, for which it acquires charges of the same type, consequently, as the charges are of the same type, they indicate that the negative force is REPULSIVE.

You are riding on your bike and stop pedaling , coasting along the road. eventually, your bike slows down and stops. what happen

andrew11 [14]

<span>When still rolling your bike had kinetic energy, or energy in the form of motion. The forces resisting this motion--a mixture of many factors including air resistance, tire friction, friction in the hubs of the wheels, etc...--eventually decrease the kinetic energy of the bike to zero as it reaches a complete stop.</span>
