The brick is solid because it's not hollow or containing spaces or gaps
Impurities selection for doping in group 14 semiconductors is: based on their ability to add more holes and fewer electrons or to add more electrons and reduce the holes.
<h3>Meaning of Semiconductors</h3>
Semiconductors can be defined as any material that has the ability to exhibit some properties of a conductor and some properties of an insulator.
A semiconductor can be used as either a conductor or an insulator when worked upon.
In conclusion, Impurities selection for doping in group 14 semiconductors is: based on their ability to add more holes and fewer electrons or to add more electrons and reduce the holes.

Answer:
1250N
Explanation:
This question is based on pascal's Law.
So By Pascal's Law
=
therefore =force on input piston =25N
= Force or weight on output person.
therefore after putting the values we get,
= (25x 1500)/30
=1250N
