Homework Statement A farsighted man uses eyeglasses with a refractive power of 2.20 diopters. Wearing the glasses 0.03 m from his eyes, he is able to read books held no closer than 0.28 m from his eyes. He would like a prescription for contact lenses to serve the same purpose. What is the...

wait oh yeah, but the Current through that point I2-I1 or I1-I2?

Alright can someone double check this? so i did for the first loop 10 - 15I1 - 10I1 + 10I2 - 10 = 0 25I1 = 10I2 then 2nd loop did 24 + 10 - 10(I2-I1) - 5I2 = 0 simplified it to => 34 = 15I2-10I1 and then to => 27.5*I1 = 34 plugged I1 in for I2 from the first equation and ended up with I1 =...

well for the first loop the +10 from the first voltage would cancel out with the one to the right of it correct? and am i looking for I2-I1 or I1-I2 when looking for the current in the 10 ohm resistor?

how do you set up the 2nd loop? V1 + 10 - 10*(I2-I1)? - 5.0*I2 ?? or is the bolded part +10*(I2-I1) or is it I2 + I1 ? or what? and does the rest of that equation look right?

Homework Statement Find the current in the 10.0 ohm resistor in the drawing (V1 = 24.0 V and R1 = 15.0 Ohm) Diagram: Homework Equations Kirchoffs loop ruleThe Attempt at a Solution well do i have to solve for both parts of the circuit if i just want to find the current at the 10.0 ohm...

also i think the 2nd one the conditional information of .7 is unecessary and it should just be that P(AB) = P(A)*P(B) = (.4)(.25) = .1?

^ that doesn't seem to work, like I'm still not clear on when I'm supposed to use baye's theorem? ah sorry forgot the final bracket it says this: Bayes Theorem : P(A|B)P(B) / [P(A|B)P(B) + P(A|B')P(B')] in the textbook it says that ah well here let me just take a picture of it:

Homework Statement I've attached both the problems into one image to make life easier since problem 1 has a diagram and the other does not. Homework Equations Bayes Theorem : P(A|B)P(B) / [P(A|B)P(B) + P(A|B')P(B')] B' = B Complement The Attempt at a Solution well for the first one i don't...

Homework Statement A sound source emits sounds of frequency 210 Hz that travel through still air at 340 m/s. The listener moves at 85 m/s relative to still air toward the stationary source. What is the wavelength of the sound between the source and the listener? Homework Equations f' = f[1+...

thank you guys, appreciate it a lot

wait so is it 3/2 or 5/2? because i have 2 equations from the formula sheet he gave us one says Cp = 5/2 * R and one says Cv = 3/2 * R ? or in this case is it the 3/2*5/2 or something?

Homework Statement If 650 J of heat are added to 21 moles of a monatomic gas at constant pressure, how much does the temperature of the gas increase? (in Kelvins) Homework Equations U = nRT Q=(5/2)nR(T2-T1) The Attempt at a Solution well how do you even know how much the...

thats what i was doing tho... 3/4 = .75 so if u do 196/.75 then square root both sides u still get like 16 something or even if u square root both sides first then multiply that fraction across its still doesn't end up with 14.46
