    Numerical problem about circuits

    PROBLEM:the current at the terminals of a certain current source is measured with an ammeter having an internal resistance R_i=10 ohms and is found to be 11.988 mA ;adding a 1.2 kilo -ohms resistance between the source terminals causes the ammeter reading to drop to 11.889 mA.Find i_s and R_s...

    Train distance physics problem

    thanx people for all ur help but @ bomba923 the sequence u have given here is a recurrence relation(if I'm not wrong) but I don't know how to solve these sort of relations!(bcoz I haven't learned it at school :cry: )If u could please solve for n I would be really thankful to u! Salman.

    Train distance physics problem

    I'm stuck... help someone! here is the problem: Two trains are traveling on the same track. One is going West at 25 km/h and the other is going East at 30 km/h. When they are 100 km apart an eagle takes off from the first train and flies at 50 km/h towards the other train. On reaching the...
