Back then, Robert Hooke found cells from a cork and named it cells. Later on, Matthias Schleiden found cells from plant parts and concluded that all plants are made of cells. Theodor Schwann, after observing many different animal cells, concluded that all animal have cells. Several years later, Rudolf Virchow hypothesized that cells divide to form new cells. Virchow proposed that every living organism has cells. His observations and conclusions and those of others are summarized in the cell theory
Answer:
Amount of energy required to change the 1kg of a substance without changing its temperature.
The spheres in the experiment could not be of equal size.
<u>Explanation:</u>
This is the concept of Electrostatics. The two metal spheres are placed on portable insulated stand so initially both have charge, q = 0. We thought to create equal and opposite charges on both the metal spheres without touching the charged glass rod to these spheres. First of all let us hold the rod at a distance R from any of the insulated sphere, making it closer to the spheres the phenomenon of induction arises. Finally the sphere near the rod will have induced opposite charges and the other sphere which is away from rod will get induced same charge of the rod. And in this process we will get opposite and equal charges in the spheres without touching them. No, it is not necessary to be the spheres of equal size.
