A80 w light bulb (normally run at 120 v) is attached to a transformer. the voltage source in the transformer is 65 v and np = 30. how many turns does the secondary coil need to be to run this light bulb at 120 w?

What are igneous intrusions and extrusions

Explain what happens at the saturation point when adding salt to water at room temperature.

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
