Simple machines help reduce the amount of work being done, as they help by using a simple function. One disadvantage is that they do not help completely.
This problem is providing information about the mass of a tennis ball, 56.6 g (0.0566 kg) and asks for the velocity it will have to equal the wavelength of green light, which is 5400 A or 540 nm (5.4x10⁻⁷ m). Thus, after doing the math, the result is 2.17x10⁻²⁶ m/s.
<h3>
Broglie's wavelength:</h3>
In this case, we recall the formula of the Broglie's wavelength as shown below:
Whereas lambda is the wavelength, h is the Planck's constant, m the mass and v the speed; thus, we solve for the speed according to the question:
<h3>Calculations:</h3>
Then, we just plug in the numbers we were given to get the answer:

D)polar covalent because ionic and metallics include metals and nonpolar covalent wouldn’t work because it’s lewis for structure and en doesn’t match its requirements.
