Q. If the mass of both weights is 225 gm, the first mass is located 20 north of east, the second mass is located 20 south of east, and the transducer sensitivity is 0.5 volts/Newton, how large a voltage do you expect to measure? Assume the transducer has been properly zeroed so that V = 0 when F3=0.
Q. Two long parallel wires carry currents of 20 A and 5 A in opposite directions. The wires are separated by 0.2 m. At what point between the two wires are the contributions into the field from the two wires the same?
A swimming pool has dimensions 32 m 11 m and a flat bottom. When the pool is filled to a depth of 2.10m with fresh water, what is the force caused by the water on the end that is 11m.
A car of mass M = 800kg travelling at 50km/hour enters a banked turn covered with ice. The road is banked at an angle 20degrees, and there is no friction between the road and the car's tires.
How will their speeds to relate to each other when they land? Ignore air resistance. Clarify with graph. Draw a graph and explain why it happens.
A 2.62 kg mass attached to a light string rotates on the horizontal, frictionless table. The radius of the circle is 0.4207 m, and string can support a mass of 14.70 kg before breaking.
A gas expands from I to F. The energy added to the gas by heat is 442 J when the gas goes from I to F along the diagonal path. What is the change in internal energy of the gas.
An electric field of 8.55x10^5 V/m is desired between two parallel plates, each of area 35.00 cm^2 and separated by 2.45mm of air. What charge should be on each plate.

The two forces in each pair could have different physical origins (for instance, one of the forces could be due to gravity, and its pair force might be due to friction or electric charge).
One mole of an ideal gas does 1408 J of work on the surroundings as it expands isother- mally to a final pressure of 1.6 atm and vol- ume of 29L. Find out the initial volume.
