12 meter long uniform plank weighing 2000N balanced on fulcrum. if the 800N object is placed on the beam 1.5 meters from it's right end where, if it all, can the fulcrum be moved such that this new system remains level and in equilibrium?

A) the system cannot be in equilibrium unless another weight is added to the left side
B) the system cannot be in equilibrium because the beam ins't long enough
C) moving the fulcrum 1.3 meters to the right of the center will balance it
D) moving the fulcrum 0.6 meters to the right of the center of the beam will balance it

To develop this problem it is necessary to use the expression that allows us to convert the degrees Celsius to Fahrenheit. The expression that allows to realize it is given mathematically by:

In this way for 33.2 °C:

In this way for 38.2°C

Expressed in a range term, we can say that the measure in degrees Fahrenheit is:
