The calculated de Broglie wavelength is 14.0 pm. Given the mass of a proton at 1.673 x 10⁻²⁷ kg and its velocity of 2.83 x 10⁴ m/s, the de Broglie wavelength is derived from the formula defined by Planck's constant.
Answer:
a) The frequency is 3.191x10^11.
b) The type of radiation is microwave radiation.
c) The energy of one quantum of this radiation amounts to 1.32x10^-3ev.

Answer:
Explanation:
As the baseball ascends, gravitational forces as well as air resistance act downward, whereas the displacement is moving upward which results in an angle of 180° between the force and displacement. Therefore, the work done by both the gravitational force and air resistance is negative, confirming option (d) as accurate.
