Answer:
We can plug in the information for the ball into this equation to determine the kinetic energy. The mass is 0.5 kg and the velocity is 10 meters per second. So: KE = (1/2)(0.5)(10)^2. Thus the kinetic energy of the ball is 25 J
Explanation:
Answer:
The correct answer is - a. water and water.
Explanation:
Water is the universal solvent as it is the most common solvent for almost most of the substances. Water mlecules are able to dissolve polar molecules that have partial positive and negative charge are readily dissolve in the water.

The answers are B, C and E :)
No they do not have defined nucleus
The appropriate answer is d. Dead plants in a swampy environment is the perfect environment for the beginning of the coal forming process. Over time layers pile up in this anaerobic environment. The plant or organic material gets buried overtime by dirt or rocks. Millions of years of burial will expose the matter to heat and pressure and will eventually lead to the formation of coal and other petroleum products.
