calculating the area of an object

The figure below gives the speed-time graph of a car moving with a uniform speed of 60 km/h for 5 hours. Speed-Time Graph of a Car Moving with Uniform Speed Distance travelled by the car (S) = v x t But 60 km/h = OC = breadth of the rectangle OABC 5h = OA = length of the rectangle OAB..

Suppose a horizontal area A (m 2 ) is supporting a column of liquid of height h (m) and density d (kgm - 3 ..

Let us now calculate the force of attraction between an object of mass 50 kg and Earth. The mass of the Earth is about 6x10 2 4 kg. The distance between the Earth and the object is approximately 64x10 5 m. The force of attraction between the object and the Ea..

Gravitational Force between two Light Objects - Let us now calculate the force of gravitation existing between two unit masses separated by a unit distance. m 1 = 1 kg m 2 = 1 kg d = 1m G = 6.6734 x 10 - 1 1 Nm 2 /kg 2 This is a very weak force. To find Force existing between tw..
