One hundred students attended at least one of three concerts: Pep Band, Country Sizzle, and Blue Mood. 48 heard the Pep Band concert. 36 heard the Country Sizzle concert. 60 heard the Blue Mood concert. 12 heard the Pep Band and Country Sizzle concerts. 20 heard the Country Sizzle and Blue Mood...

Here is the problem: A coil containing 590 turns with radius 3.85 cm, is placed in a uniform magnetic field that varies with time according to B=( 1.20×10−2 T\s)t+( 3.40×10−5 T\s^4)t^4. The coil is connected to a resistor of resistance 690 Ohms, and its plane is perpendicular to the magnetic...

Yes I was using the product rule. It has been a while since I last did derivatives so I need some refreshing. I was using a as f and the sin as G But what I get from you is that the derivative would be: bcos(bt)?

ok thanks. My math is a little rusty. right now I have B = 0.0000197*sin(2*pi*f*t) if i remember correctly the derivative of this would be f'(x)*g(x) + f(x)*g'(x)?

and for the last part ould it be taking the derivative of B and the derivative of the area? Then using the equation -N(d(BA)/dt) ?

Ok so the are of the loop. I would assume that the area of the loop is pi*r^2 with the radius being that of the smaller loop which is 1.5cm?

Alright there is a problem I was given and it has four parts, I got the first two but am having trouble with the last two. A)Consider a circular current loop of radius 10.5 cm with 200 total turns. Assume that the current through the coil is I. What is the magnitude of the magnetic field at...

I have this problem: An object is undergoing simple harmonic motion with period 0.330 s and amplitude 5.95 cm. At t=0 the object is instantaneously at rest at x= 5.95 cm. i need to find : the time it takes the object to go from x= 5.95 cm to x= −1.49 cm. I have tried using x = A cos(wt +...

for some reason that is not working for me.

sorry i guess i typed it wrong. the dampening force: F = -bv I need to find the magnitude of the dampening constant b.

Here is my problem: A hard-boiled egg of mass 45.0 g moves on the end of a spring with force constant k = 24.7 N/m. Its initial displacement is 0.290 m. A damping force F = - bv acts on the egg, and the amplitude of the motion decreases to 0.120 m in a time of 5.10 s. I need to find the...

nm I was stupid and not doing the math correctly.

That does not work out. I get an incredibly small number which I know is wrong.

Here is my problem: The star is 59 light years from the Earth and has a mass of 1.90×1030 kg. A. A large planet of mass 1.20×1028 kg is known to orbit this star. The planet is attracted to the star by a force of 3.50×1026 N when their centers are separated by a distance equal to the...

That pretty much is the complete question but I will type it out exaclty: A. What is the maximum value the angle \theta can have if the stick is to remain in equilibrium? B. Let the angle between the cord and the stick is theta = 17.0 degrees. A block of the same weight as the meter stick is...
