Answer:
is the photon energy of an x-ray
Explanation:
Given:
Energy of photon,
Then according to given:
is the wavelength
Again,
Energy of photon,
wavelength of the light,
<u>Now, photon energy for an x-ray:</u>
wavelength,
is the photon energy of an x-ray
Answer:
The height of the building is 88.63 m.
Explanation:
Given;
initial component of vertical velocity, = 12 m/s sin 26° = 5.26 m/s
initial horizontal component of the velocity, = 12 m/s cos 26° =10.786 m/s
horizontal distance traveled by the rock, x = 40.4 m
time of flight is calculated as;
x = t
t = x /
t = 40.4 / 10.786
t = 3.75 s
Determine the final vertical velocity of the ball;
Determine the height of the rock;
Therefore, the height of the building is 88.63 m.
