The chemical reaction causes electricity to flow through the terminals to the load attached. Some of the acid in the battery remains on the plates as it flows through. When the battery is recharged the acid is returned to the liquid solution to provide more power later.
An object moving with constant acceleration near the surface of the earth is influenced by the gravity. <span>In physics, </span>gravitational acceleration<span> is the </span>acceleration<span> on an object caused by the force of </span>gravitation<span>.

Answer:
Part a)
Part b)
Explanation:
Mass of the disc is given as
m = 2.00 kg
radius of the disc is given as
r = 7 cm
so moment of inertia of the disc is given as
Now given that torque on the disc is
so here the angular acceleration is given as
Part a)
if disc start from rest and then achieve final speed as 1200 rpm then
so final speed is
now the time taken to reach this speed is given as
Part b)
Number of revolution in the same time is given as
