Here, Fg = Gravitational force m1 = Mass of the  first object m2 = Mass of the second object r = distance between .....

Standard weights and scales in the market should be checked every two years because the measuring device may lose their standard due to the regular use and other factors which may bring error in the .....

Digestion is the breakdown of food into small molecules, which are then absorbed into the body. The system of organs responsible for .....

Moment of the force may be defined as the product of the force and its perpendicular distance of the line of action from the axis of rotation.

Moment = f*d

Law of moment

It states that “In the balanced condition the .....

This simple machine involves two circular objects: a larger disc and a smaller cylinder, both joined at the centre. The larger disc is called the wheel, and the smaller cylindrical object or rod is referred to as the axle. Sometimes, there may .....

As we proceed towards the tip of the branch the probability of breaking the tree is higher because the perpendicular distance of the line of action from the axis of rotation increases as a result moment of force also .....

Solution : Let the ratio of three children's ages be 6x : 9x : 11x so, by question : 6x + 9x + 11x = 650  or, 26x = 650 or, x = 25 So, share of each : 6x = 6 *25 = 150 and, 9x = 9 * 25 = 225 and, 11x = 11 * 25 =  .....

Some examples are : 1.Newton's first law is often referred to as the law of inertia – inertia is an object's tendency to resist changes in motion. - When a car brakes quickly, the passenger will be thrown forward because inertia (the .....

Here, VA = 20m/s VB = 15m/s Now,  If they are moving in opposite direction, Relative Velocity (VA-B) = VA - ( - VB )                             .....

Let's take, Vp = 25 m/s Vq = 15 m/s As they are moving in the same direction so the relative velocity VAB  VAB = VA - VB          = 25 - 15 = 10 .....

A car is moving along a straight line with its initial velocity u, distance 's', acceleration 'a', time 't' and final velocity 'v'. According to the definition of acceleration, Acceleration = Final velocity- .....

An object is said to have  uniform velocity if it moves along a fixed direction and covers equal displacements in equal intervals of time. For a body moving with uniform velocity, there is no change in velocity and hence it has .....

velocity is called vector quantity because it has both magunitude and .....

Let , a body is moving with initial velocity u m/s & uniform acceleration a, after time t seconds, it travelled  s distance and its final velocity is v m/s. Then, equations of motions are: i) v = u + at ii) s = ut + 1/2 at2 ii) v2  .....

Retardation means negative acceleration. If the velocity of a body decreases, the acceleration is negative. Example:  The acceleration of a body is -5 m/s​2. then we can say that the retardation of the body is 5 .....

Solution, Given, VAT % = 13% dis % = 15 % Let, MP of TV be x S.P = MP - dis% of MP       = x - 15/100 * x       =0.85x SP with VAT = Rs 7204 or, SP + VAT % of SP = Rs 7204 or, 0.85x + 0.1105x = 7204 or, 0.9605x = .....
