The maximum possible temperature increase of the copper is 0.076^{\circ}C

Explanation:

The energy gained by the mass of copper is equal to its change in gravitational potential energy, which is:

E=mg \Delta h

where

m = 2 kg is the mass of copper

g=9.8 m/s^2 is the acceleration of gravity

\Delta h= 3m is the change in height of the copper

Substituting,

E=(2)(9.8)(3)=58.8 J

The energy gained by the copper is related to its change in temperature by

E=mC_s \Delta T

where

m = 2 kg is the mass

C_s = 385 J/kg^{\circ} is the copper specific heat capacity

\Delta T is the change in temperature

And solving for \Delta T,

\Delta T = \frac{E}{mC_s}=\frac{58.8}{(2)(385)}=0.076^{\circ}C

If sensed fuel in the Piper Archer reaches ____ gallons in either tank, the yellow Low Fuel caution light will illuminate on the
lana66690 [7]

Answer:

10 litres.

Explanation:

The air fuel ratio for aircraft is 12:1. It is due to simplicity piper archer is equipped with continuous flow injection system. There is a fuel sensing is Piper Archer which informs the pilot about the low fuel when the fuel level reaches to as low as 10 litres only in the tank. The yellow low furl light will illuminate to alert the pilot.

Which skill involves creating representations of complex objects or processes?
Naddik [55]
Making models is a skill that involves creating a representation of complex objects or processes. Through the years, people have been creating models in order to make a clearer visualization and give reality to a certain object. Some example of model making are toys like plastic cars as a model representation of a real car, a plastic plane, model representation of a real plane and a doll, a model representation of us, human. One of the most famous model representation as of today is the film or movie making. This represents the lives of the people and show stories about how people face every challenge in life.
