Question

1.Write the important speciality of the gravitational potential enery. Draw a figure and clarify it.
2.Explain: The cellular structure is considered as a basic characteristic for classification of organisms.​

Answer 1

Explanation:

1. The change in gravitational potential energy, ΔPEg, is ΔPEg = mgh, with h being the increase in height and g the acceleration due to gravity. The gravitational potential energy of an object near Earth's surface is due to its position in the mass-Earth system.
2. The more basic characteristic for classifying organisms is the kind of cells they are made of because differentorganisms may share same habitat but may have entirely different form and structure. So, the place where they live cannot be a basis of classification.
