Answer:

<u><em>The answer is</em></u>: <u>The twelfth part (1/12) of the mass of an atom, neutral and unbound, of carbon-12.</u>

<u></u>

Explanation:

<em>The unit of unified atomic mass - symbol "u" -1 or dalton - symbol "Da" - is a standard unit of mass defined as</em> the twelfth part (1/12) of the mass of an atom, neutral and unbound , of carbon-12,<em> in its fundamental electrical and nuclear state, and is equivalent to 1,660 538 921 (73) × 10-27 kg (value recommended by CODATA). </em>

<u><em>The answer is</em></u>: <u>The twelfth part (1/12) of the mass of an atom, neutral and unbound, of carbon-12.</u>

An atomic mass unit (symbolized AMU or amu) is defined as precisely 1/12 the mass of an atom of carbon-12. The carbon-12 (C-12) atom has six protons and six neutrons in its nucleus.

5. A ball is sitting at rest on the floor. What will happen if a balanced force is applied to the ball? *
Leno4ka [110]

When the balanced force is applied on the ball It will roll away from the force.

<u>Explanation:</u>

  • A ball lies on the floor in rest. If the balanced force is applied to

         the ball, the force will push away.

  • The forces would include gravity and the forces of air particles entering the ball from almost all directions.
  • And the ground is exercising the force and shifting away from the impact.

How could you test the hypothesis that elephants interpreted the ground signal as being farther away than the air signal?
bekas [8.4K]

Answer:

One way to test the hypothesis is to create two waves, one in the air and one on the ground at the same time. One of them for the elephant to get closer and another for the elephants to move away. Observe the reaction of the animal and with this we know which sound came first.

Explanation:

This hypothesis is based on the fact that the speed of sound in air is v = 343 m / s with a small variation with temperature.

The speed of sound in solid soil is an average of the speed of its constituent media, giving values ​​between

 wood      3900 m / s

 concrete 4000 m / s

 fabrics     1540 m / s

 earth       5000 m / s wave S

 ground    7000 m / s P wave

 

we can see that the speed on solid earth is an order of magnitude greater than in air.

One way to test the hypothesis is to create two waves, one in the air and one on the ground at the same time. One of them for the elephant to get closer and another for the elephants to move away. Observe the reaction of the animal and with this we know which sound came first.

From the initial information, the wave going through the ground should arrive first.
