A short circuit in a 120 V appliance cord has a 0.200 Ω resistance. Calculate the temperature rise (in °C) of the 3.00 g of surrounding materials, assuming their specific heat capacity is 0.382 cal/(g · °C) and that it takes 0.0600 s for a circuit breaker to interrupt the current.

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c.m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
