Ejemplo 1: ¿Cuál es el tiempo que tarda el hombre para alcanzar una distancia de 3 m a una velocidad de 1.5 m/s ? Ejemplo 2: ¿Cuál será la distancia que recorre el hombre a una velocidad de 0.75 m/s y un tiempo

de 3 s?

Ejemplo 3. ¿Cuál será la velocidad que alcanza el hombre al recorrer 5 m durante 3 s?

Glass is transparent to visibile light under normal conditions; however, at extremely high intensities, glass will absorb most of the light incident upon it. this works through a process known as multiphoton absorption. in this process, several photons are absorbed at the same time. if very intense light whose photons carry 2ev of energy is shined onto a material with a band gap of 4ev, that light can be absorbed through two-photon absorption, because two photons have the right amount of energy to bridge the band gap. what is the minimum number of photons of 800-nm light that are needed to equal or exceed the band gap of fused silica glass

Suppose that f : rn → rm and that a ∈ k, where k is a connected subset of rn . suppose further that for each x ∈ k there exists a δx > 0 such that f(x) = f(y) for all y ∈ bδx (x). prove that f is constant on k; that is, f(x) = f(a) for all x ∈ k

In a hydrogen molecule there are a total of four charges, 2 protons in the two nuclei, and 2 electrons. how many unique charge-pairs are there (without double counting)?
