What is the electric field at a point 0.450 m to the left of a
-5.77*10^-9 C charge?
Include a + or - sign to indicate the
direction of the field.
(Unit = N/C)

An ionic compound can conduct electricity when a it is dissolved in water b its crystals are ground into powder c it is in solid form d it is heated to just below its melting point

6–43 a food department is kept at 2128c by a refrigerator in an environment at 308c. the total heat gain to the food department is estimated to be 3300 kj/h and the heat rejection in the condenser is 4800 kj/h. determine the power input to the compressor, in kw and the cop of the refrigerator.

What are the similarities & differences between a thermistor and a light dependent resistor in physics?
