In a certain city, the temperature normally ranges from 20 degrees fahrenheit and 80 degrees fahrenheit. write a compound inequality that describes abnormal temperature ranges for this city and then convert that inequality to degrees celsius. f=9/5c+32

Step-by-step explanation:

20≤F≤80

20=9/5c+32

-12=9/5c

-60=9c

-6.7=c

80=9/5c+32

48=9/5c

240=9c

26.7=c

-6.7≤C≤26.7

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
