A nebula is a large cloud that is formed by dust and gas present in space. Some of the nebulae may also form by the explosion of a dying star called as supernova. Also, some nebulae may prove as a precursor of new star formation. The gases which are responsible for the formation of nebulae are helium and hydrogen. The dust and gases which forms the nebula are far but they are brought together as a single mass by the action of gravity. The clumps of gases and dust get bigger and the gravitational force acting on them also increases.

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
An uncharged nonconductive hollow sphere of radius 18.0 cm surrounds a 12.0 µc charge located at the origin of a cartesian coordinate system. a drill with a radius of 1.00 mm is aligned along the z axis, and a hole is drilled in the sphere. calculate the electric flux through the hole.
