Suppose we produce X-rays not by smashing electrons into targets, but by smashing protons, which are far more massive. If the same accelerating potential difference is used for both, how would the cutoff wavelengths of the two X-rays compare? Explain. (Hint: the accelerating potential difference causes electrical potential energy to be converted into kinetic energy, that is, Δ? = −Δ? where electrical potential energy ? = ?V and V is the electrical potential difference the charged particles travel through.

. Suppose a quanton's wavefunction at a given time is y(x) = A[1 + (x/a)2]-¹, where A is an unspecified constant and a = 4.0 nm. According to the table integrals dx √ [1 + (x/a)²]² = 1 + (x/a)²+2tan ¹ (2) If we were to perform an experiment to locate the quanton at this time, what would the probability of a result between x = 0 and x = 8.0 nm?
