Technician A says that a soldering gun is generally better suited to delicate work on circuit boards than a soldering iron. Technician B says using a soldering torch heats up faster than a soldering iron. Who is right?

Both the technicians B is correct.

Explanation:

For delicate work on circuit boards the soldering iron is suitable for working because it has various sizes of iron light is weight and applies no almost force on the work piece. Whereas the solder gun forces the molten filling solder on to the work piece.

The soldering torch directly releases flame on the work piece and produces high heat so it heats the work piece faster. While a soldering iron heats up slowly and uniformly.

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
