Yes, it is true to a certain that the number of outer shell electrons determines the chemical properties of an element, only because this determines how the element interacts with other elements.
Answer:
Explanation:
If Ek is the kinetic energy and m is the mass and v is the velocity then v can be calculated as follows
Ek= 1/2 ×( m × v² )
2Ek= mv²
2Ek/m = v²
v =√(2Ek/m)
m = 0.1 kg
v= √(2x8/0.1)= 12.65 m/s

Answer:
primary advantage of composite material are high strength, low weight, corrosion resistance
Explanation:
The primary advantage of composite material is
1) high strength - they are stronger in strength than commanly used material like steel and aluminium.
2)low weight - lighter than most of the material like woods and others metals
3) corrosion resistance - it resist extreme condition of weather and can be good place where handling of chemicals takes place.
