Explanation:
Answer:
x = 16 [m]
Explanation:
This problem can be solved using the following equation of kinematics.
where:
Vf = final velocity [m/s]
Vo = initial velocity = 5 [m/s]
a = acceleration = 3 [m/s²]
t = time = 2 [s]
Now we can find the displacement using the following equation of kinematics.
Answer:
(a)
(b)
(c)
Explanation:
The Planck-Einstein relation allows us to know the energy (E) of a photon, knowing its frequency (f). According to this relation, the energy of the photon is defined as:
Here h is the Planck constant.
(a)
(b)
(c)
