Homework Statement Johnny Jumper's favorite trick is to step out of his high-rise window and fall 56.0 m into a pool. A news reporter takes a picture of 70.0 kg Johnny just before he makes a splash, using an exposure time of 7.00 ms. Find the following. (a) Johnny's de Broglie wavelength...

Homework Statement If X radiation ionizes 26.2 X 1012 atoms per cemtimeter cubed, what is the ionizing intensity of the radiation measured in roentgens ? Homework Equations The Attempt at a Solution Help, I have never seen atoms per centimeter cubed before, I know that 1...

oops :) my bad

Homework Statement A converging lens with a 50.0 mm focal length is used to focus an image of a very distant scene onto a flat screen 37.0 mm wide. What is the angular width of the scene included in the image on the screen? Homework Equations The Attempt at a Solution Basically...

Homework Statement A diffraction pattern is produced on a screen 130 cm from a single slit, using monochromatic light of wavelength 460 nm. The distance from the center of the central maximum to the first-order maximum is 2.20 mm. Calculate the slit width. (Hint: Assume that the first-order...

Homework Statement Which of the following are true for the Crystal Field Model of an octahedral complex ion? Consider ions to be from first-row transition metals. a) Two of the 3d orbitals point directly at ligands b) t2 orbitals are less stable than e orbitals...

Homework Statement Two parallel conductors carry currents in opposite directions, as shown in Figure P19.56. One conductor carries a current of 10.0 A. Point A is the midpoint between the wires, and point C is 5.00 cm to the right of the 10.0 A current. I is adjusted so that the magnetic...

Homework Statement 2. [1pt] Which of the following solutions result in a buffer ? a) 0.100 L of 0.250 M NH3 + 0.050 L of 0.250 M HCl b) 0.100 L of 0.250 M NH3 + 0.100 L of 0.250 M HCl c) 0.100 L of 0.250 M NH4Cl + 0.050 L of...

Homework Statement In Figure P18.50, suppose that the switch has been closed for a length of time sufficiently long enough for the capacitor to become fully charged. (R = 12.0 k, R2 = 17.0 k, R3 = 1.00 k, V = 9.70 V) The picture is under attachment a) Find the steady-state current in...

since the voltage is 4 V and the charge is .0001 then the total capacitance would be .000025 F. Since it's parallel C eq = C1 +C2. so C2 s 15 uF. I got it now, thank you.

what's next?

The charge for the first single cap is .0001 C

Homework Statement A 10.0 µF capacitor is fully charged across a 10.0 V battery. The capacitor is then disconnected from the battery and connected across an initially uncharged capacitor with capacitance C. The resulting voltage across each capacitor is 4.00 V. What is the value of C...

Ohh I understand it now, thank you very much

Homework Statement A solid conducting sphere of radius 2.00 cm has a charge 6.70 µC. A conducting spherical shell of inner radius 4.00 cm and outer radius 5.00 cm is concentric with the solid sphere and has a charge -3.50 µC. Find the electric field at the folowing radii from the center of...
