A resistance R and a 4.3 H inductance are in series across a 60-Hz ac voltage. The voltage across the resistor is 20 V and the voltage across the inductor is 21 V. Assume that all voltages in this problem are rms voltages. (a) What is the resistance R

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water
