To work out the gravitational potential energy of an object the equation is:GPE = m x g x hWhere:m = the mass of the object (kg)g = gravitational field strength (on earth that is 9.81 ms-2)h = height of object (h)
Net force acting on particle of mass 2 kg is 10N in north direction.At t=o, particle was moving eastwards with 10m/s. Find displacement and velocity of particle after 2 seconds.
A 92-kg man uses a 3.05-m board to attempt to move a boulder, as shown in the diagram below. He pulls the end of the board with a force equal to his weight and is able to move it t
Light is able to travel through vacuum Ans: In classical physics electromagnetic radiation (light) is the only kind of wave that doesn't need a medium. For sound rays in a
Earth is losoing heat in order balance the input outpout . But where is going that heat since there is nothing out to get it. Billions of stars are loosing heat the same way and so
why ballistic missile is unpowered and unguided
What are the steps to the scientific notation? To write in scientific notation, you should first move the decimal point of the number to where the number is among 1 and 9. For
(1) These rays transmitted in the forward direction of medium with a finite speed. (2) Energy and momentum are transmitted in the direction of propagation of waves without real
