<h2>Answer: Electric energy
</h2>
Voltaic cells use chemical reactions to generate electrical energy, as well as the reverse process.
This type of cell is mainly composed of the anode (a metal electrode where oxidation occurs) and the cathode (a metal electrode where the reduction occurs). These electrodes are placed in two compartments separated by a porous plate or membrane and immersed in a medium containing ions.
This is how, <u>when the chemical reaction of oxide-reduction occurs, electricity is generated.</u>
Answer:
0.09kg of air
Explanation:
The dimensions of the room are given
change the height to meters by dividing it by thousand.
For the volume multiplying the length,width and height (all should be in the same unit most suitable being meters).
Volume refers to the amount of space inside a box or a object.
The amount of air is equal to the volume.
Answer:

Explanation:
From the question we are told that:
Length 
Mass 
Distance from Tip 
Generally, the equation for Torque Balance is mathematically given by


Therefore

When driving a car on the road
Answer:

this force is
times more than the gravitational force
Explanation:
Kinetic Energy of the electron is given as


now the speed of electron is given as

now we have


now the maximum force due to magnetic field is given as



Now if this force is compared by the gravitational force on the electron then it is


so this force is
times more than the gravitational force
