The kinetic energy of a photon can be calculated from the product of the planck's constant and the frequency of the light. In this problem, we are given the wavelength. Frequency and wavelength are related. We do as follows:
E = hv where h is the Plank's constant and v is the frequency (v = speed of light / wavelength )
E = h (speed of light / wavelength)
E = <span>6.63x10^-34 ( 3x10^8 )/ (1.50x10^-7 )
E = 1.326x10^-18 J = 8.26 eV</span>
Answer: all atoms of the same element have the same atomic number.
Explanation:
atomic mass differentiates them, which is the same as the mass number.
Answer:cotton
Explanation: cotton absorbs sweat and heat . the sweat is evaporated and thus it cools the body . so cotton is best for summer
Answer:
A.) A cinder cone vocano
Explanation:
Cinder cone volcanos give off more ash, rather then an explosion, hense the name "cinder cone".
