Answer:
The boat won't be able to move if the oars were out and there was no thruster. If there was a flow of the water then yes there would be a moving boat.
<span>Two characteristics of regular, periodic waveforms are :
</span><span>1) Amplitude - It is the </span><span>the length and width of waves, such as sound
waves, as they move or vibrate. An example would be how
much a radio wave moving back and forth.

2) Frequency - It is the number of waves cycles per unit of time, passing a
point per unit time. It is usually measured in Hertz.</span>
Answer:
Explanation:
As with all atoms known, electrons moves in discrete energy levels round a well defined orbit.
Protons are restricted to the nucleus of an atom. They occupy this small and massive position along with the neutrons.
Metals, have a large dense cloud of electrons.
- Every atom is made up of three fundamental particles.
- Protons, neutrons and electrons are these particles.
- Protons are positively charged and they occupy the tiny nucleus. Neutrons are found in the nucleus with them. They do not carry any charge.
- It is correct to infer their position as being fixed.
- Electrons occupies the bulk of the volume of the atom.
- They orbit round the tiny nucleus.
Therefore, it is safe to conclude that in metal conductors, electrons move but protons do not just like in every other atom.
Is An object completely submerged in a fluid displaces its own volume of fluid ". This is: D
In the part of the spectrum our eyes can detect (a spectrum is an arry of entities, as light waves or particles, ordered in accordance with the magnitudes of a common physical property, as wavelength or mass) Hope this helps you :D
