When compressed forms diamonds
Speed= freq x wavelength
if freq is doubled the wavelength will halve for constant speed
Option B
Electrons has a negative charge
<u>Explanation:</u>
Electrons are the negatively charged shreds of an atom. Collectively, the positive charge of the protons in the atomic nucleus are neutralized by each of the electrons of an atom engenders a negative charge. Electrons are notably meager associated with all of the distinct components of the atom.
Electrons enclose the nucleus. Because electrons travel so speedily, it is improbable to discern where they are at a distinct instant in time. Electrons perform a dominant position in whole chemical bonds.
<span>The change in the electron's potential energy is equal to the work done on the electron by the electric field. The electron's potential energy is the stored energy relative to the electron's position in the electric field. Vcloud - Vground represents the change in Voltage. This voltage quantity is given to be 3.50 x 10^8 V, with the electron at the lower potential. The formula for calculating the change in the electron's potential energy (EPE) is found by charge x (Vcloud - Vground) = (EPEcloud - EPE ground) where charge is constant = 1.6 x 10^-19. Filling in the known quantities results in the expression 1.6 x 10^-19 (3.50 x 10^8) = (EPEcloud - EPEground) = 5.6 x 10^-11. Therefore, the change in the electron's potential energy from cloud to ground is 5.6 x 10^-11 joules.</span>
