The major difference is the presence or absence of external energy source. In an electrolytic cell, one does not need an outside source of energy like a battery while in a voltaic cell the reaction occurs simultaneously, or without help. The other major difference is that in an electrolytic cell, the flow of electrons is from positive(cathode) to negative(anode). In a voltaic cell the flow of electrons is from negative(anode) to positive(cathode).

When a comet comes close to the Sun, what happens to it that makes it bright and easier to see?

Eddi Din [679]

Answer:

Explanation:

Comet is made by dust particles, icy particles, gases etc.

A comet has a fixed time to complete a revolution around the sun.

As a comet comes nearer to the sun, due to the heat of the sun the vapour and the icy particles becomes gases and due to the radial pressure of energy od sun, we observe a tail of comet which has vapours mainly. SI the comet is visible easily.

Of the three forces acting on the rock as it slides down the bowl, which (if any) are constant and which are not? explain.

choli [55]

Answer

Hi,

The forces are; weight (gravity), Normal/centripetal force and friction. Force due to gravity is constant where as friction and centripetal are not.

Explanation

Weight is constant, given by the force of gravity on the object. The centripetal force is a function of the angles occurring between the velocity vector and the weight vector that is at right angle with the perpendicular line drawn from the surface. Friction is a function of the centripetal force thus it also varies.

Hope this helps!
