Answer:
8.79*10^6 rad/s
Explanation:
To find the frequency of the circular orbit for an electron you use the following expression, for the radius of the trajectory of an electron, that travels trough a constant magnetic field:
(1)
r: radius of the trajectory
m: mass of the electron = 9.1*10^-31 kg
v: speed of the electron = 1.0*10^6 m/s
q: charge of the electron = 1.6*10^-19 C
B: magnitude of the magnetic field = 5.0*10^-5 T
You use the fact that the angular frequency in a circular motion is given by:
Then, you solve the equation (1) in order to obtain v/r:
Finally, you replace the values of the parameters:
hence, the angular frequency is 8.79*10^6 rad/s
The frequency is:
Answer:
if he is chasing his tail faster with each circle, then that would be acceleration, If not then no
Answer:
It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
The brainstem is the innermost region of the brain. Considered to be the "trunk" of the brain, the brainstem is the posterior region of the brain composed of three main parts: medulla oblongata, pons, and midbrain. It is a continuous structure connected to the spinal cord.
1. Single dental x-rays: 
The energy of the photon is
Using the conversion factor
we can convert it into Joules:
The relationship between photon energy and wavelength is
where
is the Planck constant
is the speed of light
E is the energy
Substituting into the formula, we find
2. Microtomography: 
The energy of these photons is 2.5 times greater, so
And by applying the same formula used at point 1, we find the corresponding wavelength:
