When an object absorbs heat, it results to increase in object’s internal energy. This increase will make kinetic energy to incre

ase, therefore the temperature will also increase. Molecules move faster and faster causing the object to expand (also known as thermal expansion)How is this concept applied in loosely hung electric transmission cable wire?
a. There is more than enough budget for the cable wires
b. Tightly hung electric cable wires may snap or break due to exposure to heat
c. It is designed as provision for many users
d. It is what the law requires​​

Which of the following statements concerning the nuclear force is false? O The nuclear force is attractive and not repulsive. O
Ulleksa [173]

Answer:

  • The nuclear force is attractive and not repulsive.
  • The nuclear force is very weak and much smaller in relative magnitude than the electrostatic and gravitational forces.

Explanation:

  • Nuclear force is the strongest existing force in the nature.
  • It has the shortest range.
  • Its main function is to hold the subatomic particles together in nature.
  • The nuclear force is created  by the exchange of pi mesons between the nucleons of an atom, but for this exchange to happen the particles must be close to one another of the order of few femtometer.
  • At about 1 femtometer the nuclear force is very strongly attractive in nature but at distance greater than 2.5 femtometer it fades away.
  • The force becomes repulsive in nature at distance less than 0.7 femtometer.
  • This force holds the likely charged protons together in the nucleus.

in terms of the wavelength of the sound wave, about how far below the open end of the resonance tube is the first resonant posit
notka56 [123]

The first resonant position below the open end of the resonance tube is; <em><u>one-quarter of the wavelength</u></em>

In the event of the first resonant position in a resonance tube, there will be a maximum air displacement which is only one antinode right at the open end where the motion is constrained.

However, there will be no displacement at the closed end which means another one node right at the closed end where air is halted.

This means that the standing wave will have one-quarter of the wavelength in the test tube.

Thus;

L = ¼λ

An opera singer breaks a crystal glass with her voice. Which best explains why this occurs? The pitch of her voice matches the p
aalyn [17]

The frequency at which the body vibrates breaks is natural frequency. The glass with her voice because the frequency of her voice matches the natural frequency of the glass.

<h3>What is the natural frequency?</h3>

When there is no external force acting on the body unless the body vibrates is known as the natural frequency of vibration.it is denoted by \rm w_n.

when the frequency of a body matches the natural frequency a condition occurs known as resonance.

To learn more about the natural frequency refer to the link;
