You have designed and constructed a solenoid to produce a magnetic field equal in magnitude to that of the earth (5.0 10-5 t). if your solenoid has 350 turns and is 31 cm long, determine the current you must use in order to obtain a magnetic field.

Aphysical change is a change in the size, shape,, or stafe of matter true or false

In the circuit shown below, with each bulb holding a resistance of 60 ohms, how many amps of current are flowing? express your number as a decimal.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
