Please round to 4 decimal places, thank you so much!!! (1 point) If I,-(6260°) A in the circuit below, use phasors and nodal analysis to find ½. IB -,5 Ω 3Ω 6Ω 1020° A V2
I am having trouble understanding how the value for k3 is found in this problem. I understand the rest of the problem. If someone could explain the part to me instead of just copying and pasting the solution that would be great. Three springs and a mass are attached to a rigid, weightless bar PQ as shown in Fig. Find the natural frequency of vibration of the system. k2 ki
I have two questions I'm having trouble understanding. I greatly appreciate any help you all can give me! I'm not great at physics so the more details the better. THANKS!!! In the RC circuit of Figure WG32.6, the emf of the AC source is given by 'E = Emax sin ω| t. The emf amplitude is Emax = 10 V, and the angular frequency is ω,-100 s-1 when the angular frequency is changed to a new value ω2, the time...
Hey guys, I am having a lot of trouble with my homework. Could you please help? I thumbs up anyone who gives a thorough explanation and shows the work! I really need to understand these concepts! Thank you! 1) At 25 °C, the Ka for formic acid (HCO2H) is 1.8 x 10-4. What is the pH of a 0.10 M aqueous solution of lithium formate (LiHCO2)? 2) What is the pH (aq., 25 °C) of this solution: adding 1.64 grams...
I have asked this question before but I am having trouble understanding it. If anyone could help explain it to me it would be appreciated please! What is the gauge pressure just behind a closed faucet (at sea level) that supplies water from a water tower whose top water surface is 31 m above? a. 6 atm b. 3 atm c. 7.2 atm d. 4.8 atm
Hey guys, I am having a lot of trouble with my homework. Could you please help? I thumbs up anyone who gives a thorough explanation and shows the work! I really need to understand these concepts! Thank you! 1) At 25 °C, the pH of a 0.15 M aqueous solution of CsZ (the cesium salt of HZ) is 10.70. What is the Ka for HZ? 2) Calculate the pH of 0.586 M anilinium hydrochloride (C6H5NH3CI) solution in water at 25...
I am having trouble understanding and interpreting relative risk in a cohort study. From my understanding, it is the ratio of the risk of an exposed group to a risk of a nonexposed group. I do not understand how to interpret the ratio if it's more than 1, less than 1, or equals 1. I do not understand what it means when something has a positive association or negative association.
I have been looking over and interpreting some sample code and am having some trouble understanding what is going on with a bit of slicing syntax. For some context I am working on a computational program that uses method of finite differences approximating temperatures over a square region. Here is some of the code: maxIter = 500 lenX = lenY = 20 delta = 1 Ttop = 100 Tbottom = 0 Tleft = 0 Tright = 0 Tguess = 30...
Hey. I am having trouble with a finance question: ----------------------------------------------------------------------------------------------------------------------------------------- Consider two bonds. The first is a 6% coupon bond with six years to maturity, and a yield to maturity of 4.5% annual rate, compounded semi-annually. The second bond is a 2% coupon bond with six years to maturity and a yield to maturity of 5.0%, annual rate, compounded semi-annually. Given the data for the first two bonds, now consider a third bond: a zero coupon bond with six years...
I am having trouble understanding the right hand rule and determining the missing B-field or velocity. Please explain teh simplistic terms of using the right hand rule
