Question: 1 newton = ________ 1. 2. 3. 4. Answer: ..

Force (F) = 225 N Acceleration (a) = 2.5 m/s 2 Force (F) = ma Mass of the body = 90..

Force of Attraction Between Two Bodies of Mass m Separated by a Distance 3d That is, when the distance is doubled, the force will be reduced to 1/4 t h of the original value of force and when the distance is increased three times, the force will be reduced to 1/9 t h of the original val..

Let us now calculate the force of attraction between an object of mass 50 kg and Earth. The mass of the Earth is about 6 x 10 2 4 kg. The distance between the Earth and the object is approximately 64 x 10 5 m. The force of attraction between the object and the Ear..

Renewable energy resources are solar radiation, wind power, hydel power, biomass and nuclear power.They can be recycled and renewed by nature. These are normally pollution free. In India, unconventional energy resources are harnessed by different metho..

Question: What is the wavelength of sound waves produced in air by a vibrating tuning fork whose frequency is 256 Hz when the velocity of sound in air is 330 m s - 1 ? Answer: v = f 330 = 256 = = 1.3 ..

Potential energy = mgh = mg(h - x) [Height from the ground is (h - x)] Potential energy = mgh - mgx Kinetic energy The body covers the distance x with a velocity v. We make use of the third equation of motion to obtain velocity of the body. v 2 - u 2 = 2aS Here, u = 0, a = g and S =..
