What is an example of chemical potential energy in humans?
Brilliant_brown [7]
During cellular respiration, our bodies take glucose molecules and breaks the bonds holding the molecules together. When these bonds are broken, the chemical energy stored in these bonds are released and used to make ATP molecules, a form of useable energy for us.

Radio Waves If your favorite FM radio station broadcasts at a frequency of 104.5 MHz, what is the wavelength of the station’s si
kompoz [17]

Answer:

The wavelength of the station’s signal is 2.9 meters

The energy of a photon of the station’s electromagnetic signal is 6.9\times10^{-26}J

Explanation:

Wavelength \lambda is inversely proprtional to frequency (f) and directly proportional to velocity of the wave (v).

\lambda=\frac{v}{f} (1)

But electromagnetic waves as radio signals travel at speed of light so using this on (1):

\lambda=\frac{c}{f}=\frac{3.0\times10^{8}}{104.5\times10^{6}}\approx2.9\,m

Albert Einstein discovered that energy of electromagnetic waves was quantized in small discrete packages of energy called photons with energy:

E=hf=(6.6\times10^{-34})(104.5\times10^{6})\approx6.9\times10^{-26}J

with h the Planck's constant.

What is the nuclear binding energy in joules for an atom of helium–4? Assume the following: Mass defect = 5.0531 × 10-29 kilogra
Romashka [77]
The equation given, E = mc², can be directly used to determine the unknown amount of nuclear binding energy. Substitute the values given to the equation,
               E = (5.0531 x 10^-29 kg) x (3 x 10^8 m/s)² = 4.548 x 10^-12 J
Thus, the nuclear binding energy is equal to 4.548 x 10^-12 J.
