A profit maximizing firm will
All of the above
Use less of an input
Operates where marginal revenue equals marginal cost.
Increase in production
A firm maximizes profit by operating where marginal revenue equals marginal cost. They use less of an input in producing more products to increse their profits.

For joining two insoluble materials such as iron and silver which of the following filler material is used?
Aluminium
Cobalt
Zinc
Tin
Tin is used for joining two insoluble materials such as iron and silver because it is soluble in both the parent material (i.e. silver and iron).
When two insoluble materials such as iron and silver are supposed to join, which of the following joining process is used?
Either homogenous or heterogenous
Heterogenous
Homogenous
Autogenous
When two insoluble materials such as iron and silver are joined then heterogenous joining process is used.
Which of the following is a type of heterogeneous welding?
Gas
Soldering
Arc
Solid phase
Certain welding processes such as plasma arc welding, friction stir welding, laser beam welding, etc. can be performed in heterogenous mode.
Which of the following is a type of homogenous welding?
Brazing
Resistance
Gas
Solid phase
Gas metal arc welding (GMAW), manual metal arc welding (MMAW), flux cored arc welding (FCAW), etc. always use consumable filler material and thus can be performed in homogenous mode.
In which of the following joining process the filler material used is different as the parent material?
Either homogenous or heterogenous
Autogenous
Homogenous
Heterogenous
In heterogenous joining process the filler material used is different as the parent material.
In which of the following joining process, the filler material used is the same as the parent material?
Heterogenous
Autogenous
Either homogenous or heterogenous
Homogenous
In homogenous joining process the filler material used is the same as the parent material.
Which of the following is a type of autogenous welding?
Brazing
Gas
Arc
Resistance
Resistance welding is inherently autogenous as there is no convenient way to apply a filler material.
In which of the following welding process no filler material is added during joining?
Autogenous
Heterogenous
Either homogenous or heterogenous
Homogenous
In autogenous welding process no filler material is added during joining, the filler material can be supplied by melting the base metal.
