Particles 91, 92, and q3 are in a straight line. Particles q1 = -1.60 x 10-19 C, q2 = +1.60 x 10-19 C,
and q3 = -1.60 x 10-19 C. Particles q1 and q2 are
separated by 0.001 m. Particles q2 and q3 are
separated by 0.001 m. What is the net force on q2?
Remember: Negative forces (-F) will point Left
Positive forces (+F) will point Right

Ammonia enters the expansion valve of a refrigeration system at a pressure of 10 bar and a temperature of 18oc and exits at 6.0 bar. the refrigerant undergoes a throttling process. determine the temperature, in oc, and the quality of the refrigerant at the exit of the expansion valve.

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.

Currents in dc transmission lines can be 100 a or higher. some people are concerned that the electromagnetic fields from such lines near their homes could pose health dangers. for a line that has current 150 a and a height of 8.0 m above the ground, what magnetic field does the line produce at ground level? express your answer in teslas and as a percentage of the earth’s magnetic field, which is 0.50 g. is this value cause for worry?
