The impact behavior of plastic materials is strongly dependent upon the temperature. At high temperatures, materials are more ductile and have high impact toughness. At low temperatures, some plastics that would be ductile at room temperature become brittle.
both b and c are the right
Answer:
a)supplying the intake of an engine with air at a density greater than the density of the surrounding atmosphere
Explanation:
Supercharging is the process of supplying the intake of an engine with air at a density greater than the density of the surrounding atmosphere.
By doing this , it increases the power out put and increases the brake thermal efficiency of the engine.It also increases the volumetric efficiency of the engine.
So the our option a is right.
Answer:
A truth table is a logical expression of the given inputs specially in boolean algebra and boolean functions in computer science and digital electronics.
Explanation:
Number of variables are 3 i.e A,B and C
so the number of bits are 2^3=8
A B C A+B B+C (A+B)(B+C)
