The correct answer is C) frequency.
In fact, the frequency is the number of wave crests (or pulses) per seconds. In our problem, the machine that produces the wave pulses two times per second, so this is exactly the frequency of the compression wave.
Answer:
Mass
Explanation:
The total sum of atoms in an object is the mass of the object. There are several ways to quantify the number of atoms in a substance.
- In chemical calculations, the number of moles is a good representation of the number of atoms contained in a body.
- Mass is the amount of substances a body has.
- If we can sum up all the atoms in a substance, one will arrive at the mass of the substance
Answer:
Explanation:
We have,
Speed of an electron is 
It is required to find the De Broglie wavelength of electron. The formula for the De- Broglie wavelength is given by :
h is Planck's constant
m is mass of an electron
Plugging all the values we get :
So, the De-Broglie wavelength of an electron is 
Answer:

radiation.
conduction.
convection.
