WHAT IS A COMPOSITE
A composite is a combination of two or more different materials or elements that create a new material with improved or unique properties. It is formed by bonding or mixing different components together. The resulting composite material usually exhibits characteristics that are different from its individual components. Composites can be found in various industries and applications, such as in construction, aerospace, automotive, electronics, and sports equipment. Some common examples of composites include fiberglass, carbon fiber, and reinforced concrete.
A composite is a material made by combining two or more different substances to create a new material with enhanced properties. The substances used in a composite can be of different types, such as metals, polymers (plastics), ceramics, or even natural fibers. The combination of these materials allows composites to exhibit superior strength, stiffness, durability, and other desirable characteristics that may not be present in the individual components alone. Composites find applications in various industries, including aerospace, automotive, construction, and sports equipment, among others.
A composite number is a positive integer that is divisible by more than just itself and 1. In other words, it has at least one factor other than 1 and itself.
To determine whether a number is composite, you can follow these steps:
1. Choose a positive integer greater than 1.
2. Find all the factors of the number, excluding 1 and the number itself.
3. If you find more than two factors, then the number is composite. If you find only two factors (1 and the number itself), then the number is prime.
For example, let's consider the number 12:
1. Factors of 12: 2, 3, 4, 6
- We find four factors other than 1 and 12.
2. Since 12 has more than two factors, it is a composite number.
On the other hand, let's take the number 7:
1. Factors of 7: 1, 7
- We only have two factors, which are 1 and 7.
2. Since 7 has only two factors, it is a prime number, not composite.
