The weight of the bricks is 5000N. Calculate the mass of the bricks.
(1 kg weighs 10N)

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?

Positive ions differ from neutral atoms in that

A6.0-μf air-filled capacitor is connected across a 100-v voltage source. after the source fully charges the capacitor, the capacitor is immersed in transformer oil (of dielectric constant 4.5). how much additional charge flows from the voltage source, which remained connected during the process?
