Answer:
Explanation:
Given
According to the Faraday law of induction, induced emf is given by
Magnetic field
Amplitude of EMF induced
<em>To understand the passage between two blades, it is required </em>
<em>to travel the distance of the circumference equivalent to the </em>
<em>segment of the diameter that exists between them,</em>
Where
Ball diameter
Space time
So the angle swept out by either a blade or a space is:
Through the angular velocity
So,
In short: Electromagnetic radiation is energy that is propagated in the form of electromagnetic waves
Best example of electromagnetic radiation is sunlight. Vsible light of sunlight is only a small portion of the EM spectrum. EM radiation is a form of energy that takes many forms, f.e.: microwaves, radiowaves, etc.
Answer:
F = m a = m v / t where v is the change in velocity in time t
F = p / t since m v is equal to p
F = 2.2 (kg m / s) / 1.1 s = 2 kg-m / s^2 = 2 N
Or you can use the impulse equation
Answer:
Explanation:
the speed of the tsunami will be
v = distance / time
v = s/t
v = 2300 / 5.3
v = 434 miles/hour
To convert this to m/s, we should note that, 1 mile = 1609 m, and thus
434 miles/hr = 434 * 1609/3600
434 miles/hr = 194 m/s
The frequency, f is given by the formula
f = velocity * wavelength
f = vλ
f = 194 * 470
f = 91180 Hz = 91 kHz
Period, T = 1/f
Period T = 1.096*10^-5 s or
Period T = 1.096*10^-5 / 60
Period, T = 1.828*10^-7 minute
