Calculate the equivalent resistance of the circuit, the intensity of current flowing through each resistance and the potential difference at the terminals of each resistance. I'm not sure if the switch also has resistance

Please help me

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
