Thank you very much. I now understand the concepts of Lenz's law and magnetic fields much better, and I was able to obtain the correct answer. :)

So, the x's in the picture represent the original magnetic field, right? I assume that means the induced magnetic field (which should point out of the page) is not shown. Lenz's law says that the induced magnetic field changes in response to an induced current. I don't understand how the...

33.6 There is a ccw-induced current in the conducting loop shown in the figure. Is the magnetic field inside the loop increasing in strength, decreasing in strength, or steady? I don’t understand if the problem is referring to the induced magnetic field or the pre-existing magnetic...

Got it!

One form of nuclear radiation, beta decay, occurs when a neutron changes into a proton, an electron, and a chargeless particle called a neutrino: n -> (p+) + (e-) + tex]\upsilon[/tex] where nu is the symbol for a neutrino. When this change happens to a neutron within the nucleus of an atom, the...

QUOTE: Remember that the potential energy term on the left was from all four particles. Ah! Thank you! I now have the correct answer!

There are four spheres arranged as the four corners of a square, each sphere having a charge of 10 nC and separated from each other by a distance of 1 cm. The four 1.0 g spheres are released simultaneously and allowed to move away from each other. What is the speed of each sphere when they are...

Got it! Thanks!

n_1 moles of a monatomic gas and n_2 moles of a diatomic gas are mixed together in a container. Derive an expression for the molar specific heat at constant volume of the mixture. Expression must be in terms of n_1, n_2, and the gas constant R. I know that the molar specific heat of the...

Got it! I made an error in the above calculation when typing it in. I fixed it, and got the correct answer. Thank you for your help!

The weight of the boat is equal to the weight of the base (rho*v*g) plus the weight of the sides (rho*v*g). The volume of the sides is equal to 0.187x, where x is the height of the sides. So the weight of the boat is 216776 + 14477.5x, and this is the weight of the water displaced. The volume of...

Air flows through this tube at a rate of 1200 cm^3/sec. Assume that air is an ideal fluid. What is the height h of mercury (in cm) in the right side of the U-tube? In case the picture doesn't show up, the tube is a Venturi tube. Wide end has diameter of 2cm, narrow diameter is 4 mm, and...

I don't quite understand. The water displaced will not hold the weight of the metal base (7*10*0.4), so how could adding weight onto the boat make it float if it doesn't increase the surface area? I'm picturing a rectangular base with four sides that extend upwards, forming an open-topped box...

Got it. I was off by a factor of 10. Thanks

[SOLVED] Simple volume flow rate calculation A 1.0-cm-diameter pipe widens to 2.0 cm, then narrows to 0.5 cm. Liquid flows through the first segment at a speed of 4.0m/s. The speed in the second segment is 1m/s, and the speed in the 3rd segment is 16 m/s I thought that volume flow rate was...
