LAWS RELATED TO VECTORS

Addition of vectors

The operation of addition of two vectors can be done by using the law called parallelogram law of vector addition. The addition can be done by taking two vectors as the adjacent sides of a parallelogram by joining their tales and sum can be taken by adding their corresponding components. If A=(x1+x2+x3) and B=(y1+y2+y3).

Then A+B = (x1+y1,x2+y2,x3+y3).

Multiplication of vectors

For multiplication of two vectors, there are several techniques. Includes

Cross product: It is the operation which results in a vector that’s why it is also called as the vector product of two vectors. It is taken by the product of their magnitude and sine of the angle between them. Carried out by the formula

A × B = ||A|| ||B|| sin θ n.

Where ‘n’ is unit vector determined by the plane of two vectors.

Dot product: it is the operation results in scalar of two vectors that’s why it is also called as the scalar product of two vectors. It is taken by product of their magnitude and cosine of the angle between them.

A ⋅ B = ||A|| ||B|| cos θ.

Triple cross product and multiple products: when three vectors are multiplied then the product are called triple product and if more than three then product is multiple products.

Magnetic and non-magnetic material Class 6 Science

Magnetic and non-magnetic material Class 6 Science A magnet is a substance that is drawn to certain magnetic materials like iron, cobalt, and nickel. Magnets have the ability to draw iron to them. Natural magnets are rocks that naturally draw iron. Non-magnetic materials include things like wood, rubber, coins, feathers, leather, etc. that are not drawn to iron. Magnet characteristics It pulls magnetic materials, such as iron. The magnet's two ends are referred to as its poles. The magnet's diametrically opposed poles are drawn together. Heating, hammering, or dropping causes it to lose its characteristics. On the basis of properties types of Magnets Temporary magnets are those magnets that are magnetic for only a little duration. Typically, iron, cobalt, or nickel are used to make them. When they are close to the powerful magnet, they act like a magnet. When they are yanked away from the powerful magnet, they stop being magnetic. Permanent magnets are magnets that have magne...

What are Noble Gases? Example and noble gases name

What are Noble Gases? Example and noble gases name Noble Gases Noble gases, sometimes known as inert gases or erosions, are part of the modern periodic table's 18th group. This group is made up of the following individuals: Helium is a kind of gas (He) Neon (Ne) Argon is a gas (Ar) Krypton (Kr) Xenon is a kind of xenon gas (Xe) Radon is a gas that can cause cancer (Rn) Noble gases exist in a gaseous state under typical temperature and pressure conditions. Because all noble gases have stable electronic structures, they have very little chemical reactivity. They are monoatomic gases that do not readily form molecules. 'ns2np6' represents the basic electrical configuration of noble gases. As a result, noble gases' outermost valence shells can be deemed 'complete.' The chemical inertness of the group of 18 elements is due to this. Because of the stability of certain elements, these gases form a group. These stable elements' crusts are totally filled.
