A 75.0 ohm and 45 ohm resistor are connected in parallel and across a battery. The current is 0.294A. When the 45.0 ohm resistor is disconnected, the current from the battery drops to 0.116A. Determine the emf and the internal resistance of the battery. I had thought you use the equation: E= V+ Ir but we have to... show more

That started breaking apart at the origin of physics and was such a large mass of matter it broke at beyond light speed, starting everything then instead of trying to fit everything into a speck?

This counter intuitive way that time works led Einstein to say that... show more

Best answer: For a right cylinder (= normal, straight cylinder) Volume = area of circular base * height Area of circle = pi * (radius)^2 ensure you use same units for all measures (here, the unit is "cm") and remember that units are multiplied among themselves. Area of circle, with radius of 4 cm (half of the... show more
