The circuit below consists of three identical resistors each with resistance R=7 Ohm, two identical batteries with emfs E=9 V, and a capacitor with capacitance C=651 μF. The capacitor is initially uncharged at t = 0. (a) After a very very long time, t≫RC,...

The average energy flux in the sunlight on the Earth is ⟨S⟩=1.4×103 W/m2. You might need to use some of the following constants: Distance from earth to the sun=AU=150×109m REarth=6.4×106m RSun=7.0×108m G=6.67×10−11m3/(kgs2) MEarth=5.97219×1024kg MSun=1.98...

The magnetic vector of a plane electromagnetic wave is described as follows: B⃗ =Bmxˆsin[13 rad/m z− 3.90e9 rad/sec t] where Bm>0. This represents the full magnetic field, so that By=Bz=0. (a) What is the wavelength λ of the wave, in meters? (b) What is t...

A circuit consists of a resistor of R=7 Ω, a capacitor of C=7 μF, and an ideal self-inductor of L=0.04 H. All three are in series with a power supply that generates an EMF of 5sin(ωt) Volt. The internal resistance of both the power supply and the inductor...

An infinite straight wire carrying a current I=5 A flowing to the right is placed above a rectangular loop of wire with width w=11 cm and length L=27 cm, as shown in the figure below. The distance from the infinite wire to the closest side of the rectangl...

Two charged particles initially are traveling in the positive x direction, each with the same speed v, and enter a non-zero magnetic field at the origin O. The magnetic field for x>0 is constant, uniform and points out of the page. In the magnetic field,...

We have an infinite, non-conducting sheet of negligible thickness carrying a uniform surface charge density +σ=7.00e-6 C/m2 and, next to it, an infinite parallel slab of thickness D=17 cm with uniform volume charge density ρ=−4.94e-5 C/m3 (see sketch). No...

A circuit is composed of a capacitor C=2 μF, two resistors both with resistance R=11 Ohm, an inductor L=4.00e-2 H, a switch S, and a battery V=5 V. The internal resistance of the battery can be ignored . Reminder: The "L=x.xxenn H" notation means "L=x.xx×...

i would like to post the photo of it but i have no clue how

maybe R=Req? i'm not sure

the parentheses are confusing me for (Q_0*(1+2*T/T))

question 7 anyone?

sorry i mean question 6, question 6 anyone?

thanks a lot phy. any idea about the rest/some others?
