What is an advantage of batteries over mains power. What is an advantage of mains power over batteries

Describe the energy change involved in a chemical cell.

Explanation:

Batteries have a large advantage over other power sources by being ready to deliver on short notice – think of the quick action of the camera flash! There is no warm-up, as is the case with the internal combustion engine (ICE); battery power flows within a fraction of a second.

Batteries store energy reasonably well and for a long time. Primary batteries (non-rechargeable) hold more energy than secondary (rechargeable) and the self-discharge is lower. Lead-, nickel- and lithium-based batteries need periodic recharges to compensate for lost energy

sorry I dnt know dis one

lithosphere and asthenosphere

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
