the equal employment act

Oersted's experiment shows that a current carrying wire exerts a force on a magnetic needle and deflects it from its usual north-south position. The reverse must also be true, which was proved by the French scientist Andre Marie Ampere, who suggested that a magnet must also exert an equal..

Two equal and opposite parallel forces acting along different lines on a body constitute a coupl..

If no external force acts on a system of colliding objects, then the total momentum before collision is equal to the total momentum after collision, in the same directio..

A catalyst is usually employed to increase the speed of the reaction. Finely divided iron containing molybdenum or alumina is used as a catalyst. Molybdenum or alumina (Al 2 O 3 ) acts as a promoter and increases the efficiency of the catalyst. A mixture of iron oxide and potas..

The difference between the gravitational force and the centripetal force acting on our body is equal to our weight. If the rotation of the Earth were speeded up, then the Earth's gravitational force would be used to provide the required extra centripetal force. Hence, the weighi..

We know that the earth attracts every particle towards the centre. A body can be considered to be made up of number particles. As the size of the body is small when compared to that of the earth, the gravitational pull acting on these particles can be regarded to be parallel to each othe..

According to Newton's first law of motion every body continues to be in its state of rest or uniform motion along a straight line unless an external force acts on it. This means that a ball moving on a horizontal surface should continue to move indefinitely as no force is acting..

It is a motion along a straight line. The body moves back and forth with respect to a mean position. The body returns to a given point in the path with the same velocity after regular intervals of time. The acceleration is directly proportional to its displacement from the mean position ..

. An unbalanced force changes the state of constant velocity including zero velocity of a body on which it acts. Forces may be balanced or unbalanced. An iron ball suspended from a hook by a wire [Figure (a) shown below] has two forces acting on it, its weight, acting ..

Two equal and opposite parallel forces acting along different lines on a body constitute a couple. The turning effect of the couple is called its moment and is calculated by the product of either of the forces and the perpendicular distance between them (i.e., between their line..
