Write an algorithm for switching off the electric water heater automatically when the temperature rises to 70 o Celsius.

The algorithm for switching off the electric water heater automatically when the temperature rises to 70 o Celsius is given below.

Explanation:

Let use python code for this question.

we will use if statement to check the condition if the temperature is greater than 70.

When the temperature is 70, then the algorithm will send signal to hardware to turn yourself off.

if(temperature==70):

      print("send_turn_off_signal")

answer; ///i believe that neither technician a or technician b are correct answer(both are false);

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
