Please solve this question with showing the intermediate process. Thank you. 2) 18 p Thick copper...
please show work when possible so that I may better understand. Thank you. x=L The rail gun consists of two thick conducting rails connected to a power supply and there is a magnetic field assumed to be uniform and constant in the direction shown. A short conducting bar that is to be (or carry) the projectile is placed across the bars at x -0. The current flows through the bars as shown. The magnetic force on the bar causes it...

Can you help me to solve question B4 , please:) please B1. (a) A DC circuit is shown in Figure Bl. 1092 B A 802 702 1402 18V Figure B1 Calculate (i) the total resistance across A and B (RT); (5 marks) (11) the total current from the DC supply (Is); (3 marks) (111) the potential difference(p.d.) across the 1422 resistor (V149); (2 marks) (iv) the current flowing through 1022 (11092); (3 marks) (v) the power dissipated by RI (PT)...
Bob places a neutrally charged conducting ball next to a large, charged plate. The conducting ball is weakly attracted to the plate. What is the net charge on the plate? 1. a) Positive b) Negative c) Neutral (i.e., zero charge) d) Either positive or negative, but it is impossible to tell which A +1 C charge is at the origin, and a second +1 C charge is at position (x,y)-(2 m, 0). How much work is required to move the...
Problem 4: Read Appendix 2 below (Sec. 1.4.1 of Kasap) and then solve. A metallic back contact is applied to the CdTe solar cell of Problem 1 using a set up similar to that described in Figure 1.74 (b) on the next page. To form the metallic back contact, two evaporation sources are used, Cu and Au. An initial 3 nm layer of Cu is deposited first and then 30 nm of Au is deposited. After these depositions, the sample...
summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
