Describe in which situation the following fire extinguishers are used: Water (Red Label), Powder (Purple Label) and Carbon Dioxide (Black Label). (150 words) Design a modulo-6 counter (count from 0 to 5 (0,1,2,3,4,5,0,1...) with enable input (E) using state machine approach and JK flip flops. The counter does not count until E =1 (otherwise it stays in count = 0). It asserts an output Z to "1" when the count reaches 5. Provide the state diagram and the excitation table using JK Flip Flops only. (Don't simplify) Use the following binary assignment for the states: Count 0 = 000, Count 1= 001, Count 2010, Count 3 = 011, Count 4 = 100, Count 5 = 101). An ultra-fast pulse lasers emits pulses of 13 fs.

Taking VRY-400/0 V as reference, calculate: (a) the line currents (IR, IY & IB); (b) the power factor of the load; (c) the total active power of the load (W).

Calculate the Fourier series of the function:Use Dirichlet's theorem to find the exact value of: 5. A chemical enterprise has a capital of 1000 yuan, the annual nominal interest rate of 12%, the interest will be counted monthly, how much capital it can get according to the deposit after 3 years? How does the allocation and deallocation for stack and heapmemory differ? Frazier, Thomas R., ed. Readings in African American History. 3rd ed. Belmont (CA):Wadsworth Cengage Learning, 2001 read Chapter 11. Summarize the experiences of African American during the time of Civil Rights Movement and the development of organized protest. Describe in detail what organization were developed and their approach. Explain The organizations purpose Discuss the student sit ins Briefly discuss the Black Political Action in the South When the price of a chess set is $20 per set, 80,000 units are bought and sold. When the price increases to $50 per set, only 30,000 units are bought and sold. 1a) Recall that the regular formula for the percentage change in X is: %X= X 1X 2X 1+100% where X could be price, quantity, etc. If $20 is P 1and 80,000 is Q 1, while $50 is P 2and 30,000 is Q 2, what are the percentage changes in price and quantity, using the above formula? [3+3=6 pts. 1b) Based on your answers to 1 a), calculate the price elasticity of demand of chess sets [5 pts.]. Include the simple formula forr the price elasticity of demand in your answer. Does your answer fall in the elastic, unit elastic, or inelastic range? [2 pts.] 1c) Now, redo part 1a) but let $50 be P 1and 30,000 be Q 1, while $20 acts as P 2and 80,000 is Q 2. What are the percentage changes in price and quantity, using the formula in 1a) ? [3+3=6 pts.] 1d) Based on your answers to 1c), calculate the price elasticity of demand of chess sets [3 pts.]. Does your answer fall in the elastic, unit elastic, or inelastic range? [2 pts.] 1e) You should've gotten two very different answers for 1b) and 1d). This highlights the problems with using the regular formula for percentage change when calculating elasticities (it is widely used, however, for calculating all kinds of things in economics and finance, so don't forget it!). Recall that we modified the simple percentage change formula so that it is more robust to the choice of which values are the starting values, with the modified version: %X= (X 1+X 2)/2X 2X 1100% where the denominator has been replaced by an average of the two values of X rather than a single value of X. Using this more robust formula, calculate the percentage changes in price and quantity [3+3=6 pts.]. 1f) Finally, using your answers from 1e), once again calculate the price elasticity of demand of chess sets [3 pts.]. Does your answer fall in the elastic, unit elastic, or inelastic range? [2 pts.] How does your answer compare with your answers from 1b) and 1d)?
