Answer: Keith and Aaron only

Explanation:

Since the school record for the 100-meter dash is 18 seconds, while

Juan did 19 seconds;

Hans did 16 seconds;

Keith did 17 seconds; and

Aaron did ILELE (unknown value)

Based on this illustration, only Keith and Aaron finished the 100-meter race at a lesser time than the school record.

Thus, Keith and Aaron only are the students that have broken the school record.

How fast must a 56.5-g tennis ball travel in order to have a de Broglie wavelength that is equal to that of a photon of green li
nikklg [1K]

Answer:vv

v=2.17\times 10^{-26}\ m/s

Explanation:

The expression for the deBroglie wavelength is:

\lambda=\frac {h}{m\times v}

Where,  

\lambda is the deBroglie wavelength  

h is Plank's constant having value 6.626\times 10^{-34}\ Js

m is the mass of = 56.5\ g=0.0565\ kg

v is the speed.

Wavelength = 5400 Å = 5400\times 10^{-10}\ m

Applying in the equation as:-

5400\times 10^{-10}=\frac{6.626\times 10^{-34}}{0.0565\times v}

v=\frac{331300000}{10^{34}\times \:1.5255}\ m/s

v=2.17\times 10^{-26}\ m/s
