Answer:A loudspeaker produces a musical sound by means of the oscillation of a diaphragm. The loudness of sound produced depends upon Amplitude of vibration.
<u>Explanation:</u>
The loudness of a sound depends upon the amplitude of vibrations. A sound will be louder if the amplitude of vibration is greater but if it is smaller than sound will not be louder.
Now it is the vibration of a sound that determines it's amplitude. Amplitude signifies the maximum distance moved. It means the extent of vibration If is vibrations have more amplitude than sound will be louder but if the amplitude of vibrations is shorter than the sound will be softer.
The answer should be 11,460 because the first half-life leaves 50 percent left and the next half-life would leave 25 percent which dates the bones at 11,460 years old.
Answer:
only long-range force that affects all particles is the gravitational force.
Explanation:
In nature there are four fundamental forces: nuclear, weak, gravitational and electrical.
The last two are long-range, that is, the forces are zero for infinite distances, the current gravitational on all the particles and the electric one acts on the charged particles, without the chosen charge it is zero, the forces is also zero.
Consequently the only long-range force that affects all particles is the gravitational force.
Answer:
The force of the weight
Explanation:
When we are lying on the bed, our weight is distributed along of our body and the equivalent of the force is given by the following expression.
w = m*g
where:
m = mass [kg]
g = gravity acceleration [m/s^2]
w = weight of the body [N]
At the moment when we are sleeping our body is at equilibrium, because the mattress is exerting a force with the same amount of the weight but in the opposite direction.
