Acar and its suspension system act as a block of mass m= on a vertical spring with k 1.2 x 10 n m, which is damped when moving in the vertical direction by a damping force famp =-rý, where y is the 1200 kg sitting 4. (a) damping constant. if y is 90% of the critical value; what is the period of vertical oscillation of the car? () by what factor does the oscillation amplitude decrease within one period? ( how long does it takes for the amplitude to decrease by a factor of 1000? (50 marks) a harmonic oscillator with mass of 1 kg and a spring constant of 8.75 n m (b) is subject to a damping force fmp =-y, with y=6 kg s. the system is in equilibrium (x = 0) at time t= (0)=-45 cm s. determine the displacement x(t) and velocity (t) thereafter

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
