The kinetic energy of the ejected electrons will be 2782.5 ×10⁻²² eV.
<h3>What is threshold frequency?</h3>
The threshold frequency of incoming radiation is the lowest frequency at which photoelectric emission or electron emission is impossible.
The threshold frequency is the light frequency that causes an electron to dislodge and emit from the metal's surface.
From the photoelectric effect, the equation obtained as;
Hence,the kinetic energy of the ejected electrons will be 2782.5 ×10⁻²² eV.

<span>If
you notice that two waves combine and a part of the resulting wave has
less light intensity than either of the individual waves, you're
observing destructive interference. </span><span>Destructive interference happens when the two waves that combine have amplitudes with opposite signs,which results in subtraction- combined wave with a lower amplitude.</span>
The same thing that holds everything else 'down' --- gravity.
Answer:
A. you would want to use the 12 ound ball and the 18 mph speed in order to transfer the most kinetic energy
B. KE= 1/2 MV^2 so you would want to maximize both your Mass(weight of the ball) and Velocity(speed of the roll) in order to achive the greatest KE.
C. see image
Explanation:
Full disclosure not totally sure what you are being asked in the last one but I put togethere a rough sketch that is my best guess.
Answer:
Radio waves are electromagnetic waves
Explanation:
•Radio waves are electromagnetic waves.
•Satellites are located within our atmosphere.
•Radio waves are very high energy mechanical waves.
•Radio waves are changed to gamma rays for transmission.
