A block is placed against the vertical front of a cart. What acceleration must the cart have so that ablock A does not fall? The coefficient of static friction between the block and the cart is μ(static). How would an observer on the cart describe the behavior of the block?

Every morning and weigh yourself on your scales : Assume you are a fish. You get up every morning and weigh yourself on your scales, and find you weight 0.42N. You, being a boxfish, are a box measuring 4.174 cm per side. You see a poor, hungry fisherman, and decide to be his dinner.

Pass current through a standard coiled spring : If you pass current through a standard coiled spring, what happens to the spring? Will it expand as if pulled, contract as if compressed, or remain in its given state?

Net magnetic force per meter of wire length on wire : In Fig. 29-56, four long straight wires are perpendicular to the page, and their cross sections form a square of edge length a = 16.5 cm. Each wire carries 8.00 A, and the currents are out of the page in wires 1 and 4 and into the page in wires 2 and..

What is wavelength of electron that comes out of aluminum : An electron decays from the n = 4 orbit to the n = 1 orbit in the hydrogen atom. If the work function of aluminum is 4.3 eV, does the ensuing photon have enough energy to knock an electron out of aluminum? If so what is the wavelength of the electr..

How much power does this air conditioner draw : An air conditioner draws 12 A at 220 V ac. The connecting cord is copper wire with a diameter of 1.450 mm. how much power does this air conditioner draw? If the total length of wire is 18 m, how much power is dissipated in the wiring?

Charged particle moves through space with constant velocity : A charged particle moves through space with constant velocity (magnitude and direction). If the external magentic field is zero in this region, you can conclude that the external electric field in this region is also zero.

Light bulbs-which one burned out and why : You have two 120V light bulbs, one 25W and one 100W, that are normally connected in parallel with 120V across each. Your friend had what seemed like a good idea which was to connect them in series across a 240V power line. However, one of them burned..

What the angle between the current direction and due north : At a certain location, Earth's magnetic field of 53 µT is horizontal and directed due north. Suppose the net field is zero exactly 7.5 cm above a long, straight, horizontal wire that carries a constant current. What is (a) the magnitude of the curren..
