Alloy.....
A homogeneous mixture between two or more metals or a metal and a non metal in definite proportions is called an alloy....
examples....
1. Stainless Steel..... (mixture of iron, nickel and chromium, carbon)
2.Brass(copper and zinc)
3. Bronze (copper and tin)
Buoyant force....
The force exerted by liquid is perpendicular to the surface of the body and is equal to the product of pressure and area at that point. The resultant of all these contact forces is called buoyant Force....
