So the equation for angular velocity is
Omega = 2(3.14)/T
Where T is the total period in which the cylinder completes one revolution.
In order to find T, the tangential velocity is
V = 2(3.14)r/T
When calculated, I got V = 3.14
When you enter that into the angular velocity equation, you should get 2m/s
A. Because that’s how the wild works.
Answer:
E = 5.5 10² N /C
Explanation:
For this exercise let's use Newton's second law
F = m a
the force is electric
F = q E
we substitute
q E = m a
E =
(1)
the acceleration can be found with kinematics,
v = v₀ + a t
as the particle starts from rest v₀ = 0
a = v / t
a = 160 / 2.90
a = 55.17 m / s²
the relationship
q / m = 0.100 C / kg
m / q = 10 kg / C
we use equation 1
E = 10 55.17
E = 551.7 N / C
E = 5.517 10² N / C
ask for the result with two significant figures
E = 5.5 10² N /C
Answer:
shift the wavelength of spectral lines
Explanation:
The Doppler effect is commonly used in the field of astronomy to study the motion of astronomical objects such as a star, planets, and distant galaxies. This results in the changing of wavelength and shifting of the spectral lines, due to the relative and continuous motion of the receiver and the source. This is known as the red-shifting, where the lights in the spectrum move towards the highest wavelength, i.e towards the red light. This Doppler effect signifies that the distance between the distant galaxies and earth increases with the increasing recessional velocity.
