A parallel combination of a 8.00 X Omega; resistor and an unknown resistor R is connected in series with a 11.0 Omega; resistor and a battery. This circuit is then disassembled and the three resistors are then connected in series with each other and the same battery. In both arrangements, the current through the 8.00 X Omega; resistor is the same. What is the unknown resistance R

The earth exerts a gravitational force of 500 n on amy. what is amy’s mass in kg?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
