Answer:

<h2>option C </h2><h2>decreasing its thickness and increasing its temperature. </h2>

Explanation:

<h2>Resistance is directly proportional to length and temperature of the wire and inversely to area.</h2>

<h3>if you increase the temperature the resistance will increase.(resistance is directly proportional to temperature)</h3>

<h3>if you decrease its thickness (area) then the resistance will increase ( resistance is inversely proportional to area)</h3>

Sindrei [870]

Answer:

The correct answer is Option A (decrease).

Explanation:

  • According to Heisenberg's presumption of unpredictability, it's impossible to ascertain a quantum state viewpoint as well as momentum throughout tandem.
  • Also, unless we have accurate estimations throughout the situation, we will have a decreased consistency throughout the velocity as well as vice versa though too.

Other given choices are not connected to the given query. Thus the above is the right answer.

•<br> What happens to similar charged<br> particles and differently charged<br> particles
mixas84 [53]

Answer:

Like charges repel

Different charges attract

Explanation:

When particles of similar charges are brought together, they repel each other and increase the distance of separation. Repulsion occurs because both two electrons have negative electrical charge forcing their lines of force to repel. However, when particles of opposite charges are brought nearer to each other, they attract each other and reduce the distance of separation.
