There are two things in life, physics and everything else is stamp collecting.
Use kinematic equations for 1. Then you can work out the radius. For 2 what is the equation for potential energy of a magnetic field?
You have a pulley 13.9 cm in diameter and with a mass of 1.7 kg. You get to wondering whether the pulley is uniform. That is, is the mass evenly distributed, or is it concentrated toward the center or the rim? To find out, you hang the pulley on a hook, wrap a string around it...
2 moles of helium (He) are pumped from a gas canister into a weather balloon. The balloon at this point has a volume V1. 1 mole of nitrogen gas (N2) is added at the same temperature and pressure. The volume of the balloon changes to V2. How will the new volume of the balloon c...

When NH3 is added to solid Hg2Cl2, some of the mercury ions are oxidized and some are reduced. A reaction where the same substance is both oxidized and reduced is called a disproportionation reaction. Write equations for each of these half-reactions. HELP
just like normal equations
