The value of acceleration due to gravity on Earth is 9.8 m/s 2 . This means that when a body falls freely towards the Earth its velocity increases at the rate o..

Let the object O be viewed with our eyes which is at a distance of r, making an angle q between the two eyes as shown in the diagram. The angle q , caused by the two lines drawn from the position of the two eyes to the object, is called angle of parallax. If we can consider OA and OB as r..

The mean distance of the Earth from the Moon is about 384,400 km. Write the distance in scientific notation. => 3.844 x 10 5 or 3.844 x 10 7 or 3.844 x 10 6 or None of the above..

A TV tower has a height of 100m. How much population is covered by the TV broadcast if the average population density around the tower is 1000 km - 2 ? Given radius of earth = 6.37 x 10 6 ..

is the force with which a body of mass 1 g is attracted towards the centre of the Earth. 1 gm wt = 981g /cms 2 = 1 x 'g' dyne [g is acceleration due to gravity in CGS unit..

The radius of the coil of a tangent galvanometer is 0.16 m. How many turns of the wire should be wound on it if a current of 40 mA is to produce a deflection of 45 o ? Given: horizontal component of Earth's field is 0.36 x 10 - 4 ..

03. - The radius of the coil of a tangent galvanometer is 0.16 m. How many turns of the wire should be wound on it if a current of 40 mA is to produce a deflection of 45 o ? Given: horizontal component of Earth's field is 0.36 x 10 - 4 ..

The Sun - The sun is at the center of the solar system. Its mass is about 740 times as great as that of all the planets combined. The huge mass of the sun creates the gravitation that keeps the other objects traveling around the sun in an orderly manner. Sun The sun is a typical star, of intermedia..
