Consider three resistors with unequal resistances connected in series to a battery. Which of the following statements are true? 1. The current flowing through each of the resistors is the same and is equal to the current supplied by the battery. 2. The voltage across each of the resistors is the same and is equal in magnitude to the voltage of the battery. 3. The algebraic sum of the currents flowing through each of the three resistors is equal to the current supplied by the battery. 4. The equivalent resistance of the combination of resistors is less than the resistance of any one of the three resistors. 5. The equivalent resistance of the combination of resistors is greater than the resistance of any one of the three resistors. 6. The algebraic sum of the voltages across the three resistors is equal to the voltage supplied by the battery.

Evaluate the heat loss per meter for each of the combinations you can figure out. Summarize the result in a graphical way, such as a table, such that they are easy to read and understand.
A 280-kg piano slides 4.3 m down a 30o incline and is kept from accelerating by a man who is pushing back on it parallel to the incline. The effective coefficient of kinetic friction is 0.40.
An 18-year-old runner can complete a 10.0 km course with an average speed of 4.30 m/s. A 50-year-old runner can cover the same distance with an average speed of 3.85 m/s. How much later (in seconds) should the younger runner start in order to fini..

A singly charged ion of unknown mass moves in a circle of radius 14cm in a magnetic field of 8.2 T. The ion was accelerated through a potential difference of 9kV before it entered the magnetic field.What is the mass of the ion.
Young Jeffrey is bored, and decides to throw some things out of the window for fun. But since he is also very curious, he decides to do so in a controlled way.
Suppose the traffic light is hung so that the tensions T1 and T2 are both equal to 84.7 N. Find the new angles they make regarding the x axis. (By symmetry, these angles would be the same.)
what was (a) the negative charge in coulombs on one of them and (b) the positive charge in coulombs on the other.
If a car moving at 82 takes 300 to stop with uniform acceleration after its brakes is applied, how far will it take to stop under the same conditions if its initial velocity is 41.
A uniform electric field exists in the region between two oppositely charged parallel plates 1.67cm apart. A proton is released from rest at the surface of the positively charged plate and strikes the surface of the conflicting plate in a time int..
