Answer:

q_end = q / 4  

Explanation:

Since the balls are in insulating barrels, it has no charge exchange with the earth, so it maintains its initial charge.

 

When the ball a touches the ball b and since the two are metallic the charge is distributed over the entire surface, by separating the two spheres that are of the same radius, the load was distributed between the two,

           

              q_end = q₀ / 2

              q_end = (q / 2) / 2

              q_end = q / 4

This is the charge on each ball.

If we keep touching the balls nothing else happens because the charges are already equal in both.

Does gravity have an effect on the potential difference of a battery?
Sonja [21]

Answer: The correct answer is "No".

Explanation:

Gravity: It is the force which causes object to fall on the earth. It is the force which attracts bodies towards each other.

Potential difference: It is defined as the potential acting between the two points. The work done in moving the unit positive charge from one location to the another location.

The potential difference in battery is caused by the electrodes. There are two terminals in battery: Negative terminal which is at lower potential and Positive terminal which is at higher potential. It forces the electrons to flow in the circuit which constitutes the current.

The gravity and the potential difference have no relation between them.

Therefore, gravity have no effect on the potential difference of a battery.

You have a string with a mass of 0.0127 kg. You stretch the string with a force of 9.33 N, giving it a length of 1.93 m. Then, y
melomori [17]

Answer:

wavelength = 0.968 m

frequency = 39.02 Hz

Explanation:

given data

mass = 0.0127 kg

force = 9.33 N

length = 1.93 m

to find out

wavelength and Frequency

solution

we know here linear density that is

linear density = \frac{mass}{length}   .........1

linear density = \frac{0.0127}{1.93}

linear density = 6.5803 × 10^{-3} kg/m

so

wavelength will be here

wavelength = \frac{2L}{n}   ..............2

here n = 4 for forth harmonic

wavelength = \frac{2*1.93}{4}

wavelength = 0.968 m

and

frequency will be for 4th normal mode of vibration is

frequency = \frac{4}{2L} \sqrt{\frac{tension}{linear\ density} }    ..........3

frequency = \frac{4}{2*1.93} \sqrt{\frac{9.33}{6.5803*10^{-3}} }

frequency = 1.036269 × 37.654594

frequency = 39.02 Hz

Technician A says the charging system recharges the battery by supplying a constant and relatively low charge to the battery. Te
brilliants [131]

Answer:

Technician B is correct

Explanation:

Charging systems works on the principle of magnetism. Charging system uses electromagnetic induction to generate electrical energy.

Electromagnetic principles states that voltage will be produced when there is a motion between conductor and the magnetic field.
