    L, E and i: 50.0mH Inductor and 24.0V AC Voltage Source

    So is it , V/I=Lw then V/LI=w=2pi*f .

    Diffraction pattern of a light beam from a narrow slit

    Actually, I'm studying for my entrance exams to college. I think the professor made a mistake. So , the question says : A diffraction pattern of a light beam from a narrow slit and from a thread are : a)Completely identical b)Totally different c)Identical except for the center. He...

    L, E and i: 50.0mH Inductor and 24.0V AC Voltage Source

    So,impedance is : z=Lw = L*2pi*f ... A guess , z = V/I = E/i ! but V(max)/I(max)

    L, E and i: 50.0mH Inductor and 24.0V AC Voltage Source

    A 50.0mh inductor is connected to an ac voltage source of 24.0V.The current flowing in this circuit is 0.60A.The frequency of the voltage source is : a)50Hz b)60Hz c)1.27*10^3 Hz My Work so far ! : f = w/2pi. But here we have L , E and i. Any help will be welcomed.

    Power mechanics physics problem

    A 50kg student climbs a 5.0m long rope and stops at the top.What must her average speed be in order to match the power output of 200w. a)0.20m/s b)0.41m/s c)0.10m/s My Work : And stops at the top => v=0 and h=5m so I'll use mgh. Now power output = variation of energy/1 But average...

    Calculating Spring Constant for Mechanical Oscillation

    A 4.0kg block extends a spring 16cm from its unstretched position.The block is removed and a 0.50Kg body is hung from the same spring.If the spring is stretched and released,the period of oscillation is : a)0.28s b)0.02s c)0.42s My Work : T = 2pi/w T = 2pi*sqrt{Mass Totall/K} I...
