<span>longitudinal waves is the answer hope this helps</span>
Answer:
Explanation:
Given that:
The energy of the photon = 2.3 eV
Energy in eV can be converted to energy in J as:
1 eV = 1.60 × 10⁻¹⁹ J
So, Energy = 
Considering
Where,
h is Plank's constant having value 
c is the speed of light having value 
is the wavelength of the light being bombarded
Thus,
Also,
1 m = 10⁻⁹ nm
So,
The circulatory system is responsible for bringing food and oxygen to every cell in your body. The respiratory system is responsible for carrying oxygen and carbon dioxide in and out of your body.

Explanation:
In the chemical industry, acids react in neutralization reactions to produce salts. For example, nitric acid reacts with ammonia to produce ammonium nitrate, a fertilizer. Additionally, carboxylic acids can be esterified with alcohols, to produce esters.
Acids are used to remove mineral deposits, rust stains, and hard water deposits. They can remove discoloration from some metals, such as aluminum, brass, bronze, and copper. Some acids are effective both in cleaning and disinfecting surfaces.
The energy released by 1 atom of Uranium is Q=185.*10^6-25.
The energy needed for U.S. that I will name Q2, in eV is: 1*10^19J* (1eV/(1.602*10^-19))=6.2422*10^37eV
Q=mc^2
Q2=mc^2
m is the mass of Uranium in kg that we calculated at 3.90*10^-25. We need to fund m2 because that is the unknown mass in the equation for Q2 to give us the energy for the U.S. and remember, Q is the energy that 1 atom of Uranium gives out which is why we took a ratio.
m2=Q2/Q*m=1.3*10^5 kg (final answer)
