Sladkaya [172]

Answer:

One might think of a plucked guitar string - the sound would depend on the original amplitude of the disturbance -

Speed and velocity would still be the same

(b) is correct because the energy transfer depends on the original energy applied.

denpristay [2]

Answer:

 U = 25 J

Explanation:

The energy in a set of charges is given by

          U = k \sum \frac{q_i}{r_i}

in this case we have three charges of equal magnitude

          q = q₁ = q₂ = q₃

with the configuration of an equilateral triangle all distances are worth

          d = a

          U = k ( \frac{q_1q_2}{ r_1_2 } + \frac{q_1q_3}{r_1_3} + \frac{q_2q_3}{r_2_3} )

we substitute

           15 = k q² (3 / a)

            k q² /a = 5

For the second configuration a load is moved to the measured point of the other two

          d₁₃ = a

The distance to charge 2 that is at the midpoint of the other two is

          d₁₂ = d₂₃ = a / 2

           U = k (\frac{q_1q_2}{ r_1_2 } + \frac{q_1q_3}{r_1_3} + \frac{q_2q_3}{r_2_3})

            U = k q² (  \frac{2}{a} + \frac{1}{a} + \frac{2}{a} )

            U = (kq² /a) 5

substituting

            U = 5 5

            U = 25 J

If two ends A and B are connected through a metallic wire. If electrons flows from point B to point A. What can you say about th
Ivan

Answer:

Point A is at higher potential than point B

Explanation:

Electrons are negatively charged - this means that they are attracted by positive charges and repelled by negative charges.

This also means that they tend to move in a direction opposite to the electric field lines (because electric field lines point away from a positive charge and toward a negative charge). So, they also tend to move from a point at lower potential to a point at higher potential.

In this problem, the electrons flow from point B to point A: therefore, point A must have higher potential than point B.
