As shown in the figure, a metal bar is in contact with a pair of parallel rails and is in motion with an upward velocity of magnitude v. A uniform magnetic field is present, directed downward as shown. The direction of the induced magnetic field (as a result of the induced emf) is Upward No magnetic field is induced. From b to a о не 1. What is the aldol addition product formed from the reaction of the following compound...
Please solve this question with showing the intermediate
process.
Thank you.
2) 18 p Thick copper wire Conducting connections between rails A current I, = 10 kA is flowing through a thick copper wire. Parallel to the wire, a conducting bar of width w = 10 cm is moving with speed v = 10 m/s, dragged by an external force guided by conducting rails with the same distance as the width of the bar. The rail closer to the copper...
Will someone please solve this and explain every single step? I
keep getting lost. Thank you!
The figure shows the magnetic flux through a single loop coil as a function of time. If phi_0 = 2 times 10^-2 Wb, calculate the induced emf in the coil at the following times. t = 0.05 s Your response differs from the correct answer by more than 10%. Double check your calculations. V t = 0.15 s t = 0.5 s V
PLEASE HELP ME AND SHOW STEPS. THANK YOU
1) It is desined to step up a vollage of 120 V to 96,000 v. The turns ratio N/N, of the transformer a) I/28 b) (64 x 10y )28 d) 8001 if the voltage is stepped that power is not lost in an ideal transformer, consider the situation in the above question. 2) Starting from the idea t up 800 times, the current is a) the same, since power is the same...
I need help to write a nice introduction for experiment 6
please ( no hands write ) typing
Thank you
HEAT TREATMENT OF STEELS EXPERIMENT 6 EXPERIMENT 6 HEAT TREATMENT OF STEELS THEORY The Effect of Cooling Rate One of the most convenient methods for controlling the properties of a given steel, i.e., a steel whose composition is already fixed, consists of austenizing the steel and ten cooling to room temperature at some predetermined rate. A variation of cooling rates...
