When an automotive battery is fully charged, the mixture of water
and sulfuric acid in it has a specific gravity of about 1.3 .
Answer:
Explanation:
It means that you only need apply 1/4th of the actual force required to operate the lever as you have an mechanical advantage which permits you to do 4 times the work with the same amount of effort.
<h3>What is Free-fall acceleration?</h3>
The acceleration is constant and equal to the gravitational acceleration g which is 9.8 m/s at sea level on the Earth.
As we know that charge and its sign that remains in equilibrium is under gravity must be such that it will balance the gravitational force by electric force,
mg =qE
and its sign must be negative so that it will have upward electric force
so it is
The charge of a particle of mass is

Because the kinetic energy start to decrease, for example if we put sugar in a high temperature tea and we shake it what will happen to the sugar will the kinetic energy increase or decrease, it will probably decrease, just like us the people when we enter a cold room and we have a hot temp.
Wavelength = (speed) / (frequency)
Wavelength = (320 m/s) / (300 / sec)
Wavelength = (1 and 1/15) m/s
