Explanation:
Given that,
Wavelength = 6.0 nm
de Broglie wavelength = 6.0 nm
(a). We need to calculate the energy of photon
Using formula of energy
(b). We need to calculate the kinetic energy of an electron
Using formula of kinetic energy
Put the value into the formula
(c). We need to calculate the energy of photon
Using formula of energy
(d). We need to calculate the kinetic energy of an electron
Using formula of kinetic energy
Put the value into the formula
Hence, This is the required solution.
Answer:
t = 36π seconds
Explanation:
For resolving this problem, we are going to consider a representative stadium of the United States. The Mercedes-Benz Stadium located in Atlanta, Georgia has an average radius of 90 m.
Then, its circumference measures:
L = 2πr
L = 2π(90)
L = 180π m
First, we estimate the wave's velocity: the average width of an person is 0.5 m, then the velocity is:
v = x/t
Where x: person's width
t: time
v = 0.5/0.1 = 5 m/s
The time required for the pulse to make one circuit around the stadium is:
t = x/v = 180π/5 = 36π seconds
Answer:
<h3>Motion which repeats itself after regular intervals of time is known as periodic motion.</h3>
