Answer:
Max kinetic energy for 340 nm wavelength will be
Explanation:
In first case wavelength of electromagnetic radiation
Plank's constant
Maximum kinetic energy = 0.54 eV
Energy is given by
We know that energy is given
, here
is work function
So
Now wavelength of second radiation = 340 nm
So energy
So
The ball will decelerate as it moves upwards.
The magnitude of the ball's acceleration is 0.3 m/s² and it directed backwards.
The given parameters;
As the ball rolls up the inclined plane, the velocity decreases and eventually becomes zero when the ball reaches the highest point of the plane.
Thus, the ball decelerate as it moves upwards.
The acceleration of the ball is calculate as;
<em>at the highest point on the incline plane, the final velocity </em><em> is zero</em>
Thus, the magnitude of the ball's acceleration is 0.3 m/s² and it directed backwards.
