Final temperature of puddle once it settled to equilibrium : A 0.5750-kg ice cube at -12.40°C is placed inside a chamber of steam at 365.0°C. Later, you notice that the ice cube has completely melted into a puddle of water. If the chamber initially contained 6.430 moles of steam (water) molecules before the ic..

Mass are acted on with the same magnitude net force : A 10 kg and a 4 kg mass are acted on with the same magnitude net force (which remains constant) for the same period of time. Both masses are at rest before the force is applied. After this time, the 10 kg mass moves with a speed v1 and the 4 kg mass ..

Closer to either of the charges : A +60 µC charge is placed 48 cm from an identical +60 µC charge. How much work would be needed to move a +0.59 µC test charge from a point midway among them to a point 5.0cm closer to either of the charges?

Positively charged conducting spheres fixed in space : There are two identical, positively charged conducting spheres fixed in space. The spheres are 48.8 cm apart (center to center) and repel each other with an electrostatic force of F1 = 0.0795 N. Then, a thin conducting wire connects the spheres, redi..

What is the actual separation of the slits : Images of a slit pair and a transparent scale, with centimetre graduations, are projected onto a distant screen. If a length of 2 cm on the scale is magnified to a length of 36.1 cm on the screen, and the separation of the slit centres is magnified t..

Fixed charge does particle obtain before it comes to rest : A positive charge of 5.50 C is fixed in place. From a distance of 3.70 cm a particle of mass 5.60 g and charge +3.10 C is fired by an initial speed of 80.0 m/s directly toward the fixed charge. How close to the fixed charge does the particle obtain b..

Compute the potential difference between the two plates : Two plates of area 7.00×10-3 m2 are separated with a distance of 4.80×10-4 m. If a charge of 3.40×10-8 C is moved from one plate to the other, compute the potential difference (voltage) between the two plates. Suppose that the separation distance is ..
