Nevermind, I managed to figure the problem out myself.

Homework Statement A solenoid with a radius of 8.0 10-3 m and 170 turns/cm is used as an inductor in a circuit. When the solenoid is connected to a source of 15 V rms at 22 kHz, an rms current of 3.7 10-2 A is measured. Assume the resistance of the solenoid is negligible. (a) What is the...

I'm trying to finish my ochem homework, but I'm having difficulty solving these 3 problems. I'm suppose to name 2 of them while the third asks me to draw the model. Hopefully someone can take their time and help me. First problem: http://imgur.com/3FJEi.png Second problem...

ok thanks, that was my mistake.

Trying to finish some online ochem homework, but I'm having trouble with this one. I'm suppose to name the compound shown in the diagram attached, but apparently it's not right. Can someone help me with this one? (Diagram: http://imgur.com/n2yGz.png )

Both parents are heterozygous dominant and have the disease for dentinogenesis imperfecta.

Homework Statement What is the probability that two children have detinogenesis imperfecta and four are normal Homework Equations variables: n= # of offsprings k= certain phenotype binomial coefficient: n!/k!(n-k)! This probability is given by: Prob(Offspring has...

ok I finally figured out the second question two, it took me a few attempts because I was confused with the SI units. I pretty much used this equation: sqrt (EA^2+EB^2)

Homework Statement 1. A tiny sphere with a charge of q = +8.2 µC is attached to a spring. Two other tiny charged spheres, each with a charge of -4.0 µC, are placed in the positions shown in the figure, in which b = 4.2 cm. The spring stretches 5.0 cm from its previous equilibrium position...

ok, i tried to work out a and b, but still no luck. here's my work: (a) Given: r=.23m, q1=q2, f=.04N Equations needed:F=k((q1q2)/r^2), where k is approx 8.9910^9 Nm^2/C^2 Solution: Since q1=q2, we can substitute q2 for q1 in the equation F=k((q1q1)/r^2) F=k*((q1^2)/r^2) F/k=(q1^2)/r^2...

These are the problems I have left to do, but I have no clue as to how to solve them. Homework Statement a. Two small metal spheres are 23.0 cm apart. The spheres have equal amounts of negative charge and repel each other with a force of 0.040 N. What is the charge on each sphere? b.A tiny...
