Angular velocity is the rate of change of angle of a body, i.e. omega = v / r = (2*pi*r)/ r*t = (2*pi)/ T. where T is the time period of whatever is rotating and r is the radius of the circle. So if a circular disc is spinning at 1 m/s then the angular velocity of it is 2*pi radians/ second.
First shell hold up to 2 electrons.
Answer:
the correct answer is C v = 60 cm / s
Explanation:
The speed of a wave is related to the frequency and the wavelength
v = λ f
They indicate that the object performs 20 oscillations every second, this is the frequency
f = 20 Hz
the wavelength is the distance until the wave repeats, the distance between two consecutive peaks corresponds to the wavelength
λ = 3 cm = 0.03 m
let's calculate
v = 20 0.03
v = 0.6 m / s
v = 60 cm / s
the correct answer is C
Answer:both are body waves often associated with seismic waves
Explanation:
Both are body waves often associated with seismic waves as in earthquakes
Hi there!
We can begin by calculating the voltage drop across the 30 Ω resistor using the equation:
V = IR
V = Potential Difference (V)
I = Current (A)
R = Resistance (Ω)
Calculate the voltage. Recall that the current is CONSTANT across a series circuit.
V = 0.12 × 30 = 3.6 V
Voltage ADDS UP in a series, so:
Total V = V1 + V2
6 = 3.6 + V2
<u>V2 = 2.4V. The correct answer is A.</u>
