Tipos de energías alternativas como el hidrogeno, la biomasa y la energía nuclear.

wavelength divides in half and speed stays the same.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

e/c, where e is its total energy

answera compound;
