Bits of paper are attracted to an electrified comb or rod, even though they have nonet charge. How is this possible?

Physics
1 answer:
SashulF [63]3 years ago
7 0

Explanation:

An electrified comb is charged comb ( let say by running it through the hair) and when it is brought in the proximity of  pieces of paper, the pieces tend to cling to it. This happens because the charged comb induces an opposite charge in the paper pieces and as opposite charges attract each other, the pieces are clinged.

hoa [83]

Answer:

Stress = 4.67 * 10^-7 N/m²

Explanation:

Young's modulus of the material = Stress/Strain

Given

Young's modulus  = 228 x 10^9 Pa

Stress =  106,483 Pa

Required

Strain

From the formula;

Strain = Stress/Young modulus

Strain =  106,483 /228 x 10^9

Stress = 4.67 * 10^-7 N/m²

In a given chemical reaction, the energy of the products is greater than the energy of the reactants. Which statement is true fo
Flura [38]

Energy is released in the reaction

Explanation:

In a given where the energy of the products is greater than that of the reactants, we can infer that energy is released in the reaction.

This indicates that the reaction is an exothermic or exergonic reaction.

These reaction types are accompanied by release of energy.

  • In an exothermic change energy is released to the surroundings.
  • The surrounding becomes hotter at the end of the change.
  • This applies in exergonic reaction which leaves a reaction having more energy than it originally started with.

Describe an application where a parallel circuit might work better than a series circuit
babunello [35]
In rooms where there are multiple lights, a parallel circuit is better.

In a series circuit, if one light broke, all of the lights would turn off, as the circuit would be broken.

However, in parallel, if one bulb broke, the circuit could still be complete through the other bulbs, so they will stay on.
