2 criticalF m 2m2 A) For a frictionless system, resonance occurs when the system is driven at the natural frequency wo vk/m. If we take the friction out of the spring-mass system. we're studying, we have m 1 and k 26 still. Calculate the natural frequency of this frictionless system, compare it to the critical driving frequency for the system with friction included, and draw a conclusion about the effect of friction on the frequency at which resonance occurs. B)...

PLEASE ANSWER A-E
Worksheet for Exploration 31.7: RLC Circuit Assume ideal components. The graph shows the voltage across the source (red) and the current from the source (black) as functions of time (voltage is given in volts, current is given in milliamperes, and time is given in seconds). Restart Ta 000 An RLC circuit is similar to an oscillating spring or Hal child on a swing. If you push the swing at exactly the same frequency as the natural frequency...

M i ques more work: Stretching a stiff spring a certain distance or stretching a weak spring the same distance? Defend your answer. - Stretching a stiff spring. This is simply because a stiff spring is more resistant to movement which requires more force or work to move it. 3. An object that has a small mass and...

Learning Goal: To understand the use of phasor diagrams in calculating the impedance and resonance conditions in a series L-R-C circuit. At resonance, XL = Xc. The voltage across the capacitor exactly cancels that across the i have the same amplitude. Thus, the inductor and capacitor effectively cancel out in the formu not come as a surprise that the resonant frequency equals the natural frequency of the oscilla In this problem, you will consider a series L-R-C circuit, containing a...

Question 1: Motion on a horizontal plane [25] On a horizontal plane, a force of 58 N in the horizontal direction acts on an object of mass 10 kg. (1) Find the magnitude of the normal force N acting on the object from the plane. (2) Neglecting friction, find the magnitude of the acceleration a of the object. (3) Assuming that the coefficient of friction between the object and the plane is 0.50, find the magnitude of the acceleration a...

4. A spring is stretch 10 cm by a force of 3 N. A mass of 2 kg is hung from the spring and is also attached to a viscous damper that exerts a force of 3 N when the velocity of the mass is 5 m/s. If the mass is pulled down 5 cm below its equilibrium position and given an initial donward velocity of 10 cm/s determine its position u at any time t. Find the quasi-frequency μ...

3. A spring stretches 3.0 cm from its relaxed length when a force of 7.5 N is applied. A particle with a mass of 0.5 kg rests on a frictionless horizontal surface and is attached to the free end of the spring: The particle is pulled horizontally so that it stretches the spring 5.0 cm and is then released from rest at t 0. (a) What is the force constant of the spring? (b) What are the period, frequency, f,...
