Due to diffraction effects at the aperture, the size of the smallest detail that a microscope can resolve equals one wavelength. since the wavelength of visible light is λ∼500nm, a light microscope cannot resolve any details smaller than this length. what must be the minimum energy of the electrons in an electron microscope if it is to attain a resolution as least as good as a light microscope? (in practice, energies used in electron microscopes are usually more than 10 kev, and their resolution is not limited by the wave properties of the electrons.)

A1000-kg weather rocket is launched straight up. the rocket motor provides a constant acceleration for 16-s, then the motor stops. the rocket altitude 20-s after launch is 510-m. you can ignore any effects of air resistance. a. what was the rocket’s acceleration during the first 16-s? b. what is the rocket’s speed as it passes through a cloud 5100-m above the ground?
