Removing salt from water would decrease molarity, molality and ossmotic pressure.
Answer:
4.14 eV
Explanation:
f = 1.0 ×10^15 Hz
h= 6.63×10^-34 J s ( this is called PLANCK 'S CONSTANT)
ENEGY = E = ?
E = hf ( THIS IS FORMULA FOR ENERGY OF ONE QUANTA OR ONE PHOTON )
E= 6.63×10^-34×1.0 ×10^15
E = 6.63×10^-19 J
As 1eV = 1.6×10^-19 J so changing energy in eV from joules we will divide energy by 1.6×10^-19
hence E in eV = 6.63×10^-19/(1.6×10^-19)
E = 4.14 eV
Answer:
The correct answer is option B) Mechanical waves tend to have longer wavelengths.
Explanation:
Before we begin, let's clarify what these two types of waves are.
Both electromagnetic waves and mechanical waves are classified by their ability to transmit energy in empty space.
<u>Electromagnetic waves are capable of doing that, but mechanical waves are not.</u>
The light waves that reach our planet are an example of electromagnetic waves.
On the other hand, mechanical waves need a medium to be able to move energy, it is not the same as with electromagnetic waves that are capable of transporting it on their own.
An example of a mechanical wave is sound. Sound is not capable of traveling in empty space.
This leads us to the conclusion that Mechanical waves tend to have longer wavelengths.
Answer:
Sempre que os corpos vibram e as vibrações se propagam num meio material como o ar, produzem ondas sonoras que são ondas de pressão?
Explanation:
The potential difference between the two points if the work done on the charge is +3.4×10^7 joules would be A. 10volts.
