There's a crest and a trough in each complete wave. So the question is describing 10 complete waves.
After that, the question becomes somewhat murky. It goes on to say "its time period is 0.2 seconds".
-- The "time period" of a wave is usually defined as the time for <u><em>one</em></u> complete wave. If that's what the phrase means, then ...
Frequency = ( 1/0.2sec )
<em>Frequency = 5 Hz.</em>
<em>= = = = = = = = = =</em>
<u>BUT</u> ... Is the question awkwardly trying to tell us that the <u><em>10 waves</em></u> take 0.2 seconds ? If that's what it's saying, then ...
Frequency = (10) / (0.2 sec)
<em>Frequency = 50 Hz .</em>
Substances that move to the stronger parts of a magnetic field are termed paramagnetic substances; the atomic feature responsible for this property is presence of unpaired electrons in atoms.
<h3>What is a paramagnetic substance?</h3>
A paramagnetic substance is the substance that possess unpaired electrons that are heavily attracted in a magnetic field.
A magnetic field is defined as the field that exists around a magnet that produces a field of force.
Examples of paramagnetic substance include the following:
- aluminum,
- gold,
- copper.
- Chromium, and
- Manganese.
These substances are known as paramagnetic substances because they possess a high number of unpaired electrons.
Other properties of a paramagnetic substance include the following:
- They have a permanent dipole moment or permanent magnetic moment.
- They are weakly magnetized in the direction of the magnetizing field.
- They usually have constant relative permeability (μr) slightly greater than 1.
Therefore, Substances that move to the stronger parts of a magnetic field are termed paramagnetic substances; the atomic feature responsible for this property is presence of unpaired electrons in atoms.

The currents responsible for powering the movement of tectonic plates is convection currents which occur in the mantle. As the hotter, less dense liquid rises it displaces the cooler more dense liquid which moves the tectonic plates out of allignment
The boat's initial velocity is:
While the boat's acceleration is
with a negative sign, since the boat is slowing down, so it is a deceleration. The distance traveled by the boat until it comes to a stop can be found by using the following equation:
where vf=0 is the final velocity of the boat and S is the distance covered. Re-arranging the formula, we can find S:
Answer:
They investigated Hooke's law.
Explanation:
