... (a) So, E = − 2r Ḃ, and taking the derivative gives Ḃ = 40π cos (20πt), and so E = −20πr cos (20πt) V/m, which has it’s maximum value when 20πt = π, 3π, · · · . In this case the cosine term is 1, and so Emax = 20πr V/m. So, at r = 1.5 cm, then Emax = 20π (0.015) = 0.94 V/m. (b) The electric field ...

Notes on Newton`s Laws of Motion
... Newton’s Second Law of Motion • “The acceleration of an object is equal to the net force acting on it divided by the object’s mass” • Acceleration = net force/mass, or a = F/m • Mass is the amount of matter in an object and stays constant • Weight is the force of gravity on an object and can change ...

... (e) (10 points) Resonance behavior means that the amplitude of the oscillations becomes large at a specific frequency (the resonance frequency) of the applied force. We can see that the first term indeed shows resonance at ω = ω0 . When ω = ω0 the amplitude goes to infinity. This is not physical: it ...
