The greater the speed of two identical masses, the greater the kinetic energy. So, the mass that is traveling twice as fast as the other has much more kinetic energy. The formula for kinetic energy is KE=m*v^2 (kinetic energy equals mass times velocity squared), and velocity is the same as speed in this case because it is squared. So, the mass traveling twice as fast has 4 times the kinetic energy, because 2 squared=2*2=4.
Answer: The mass traveling twice as fast has four times the kinetic energy.
The answer is A because it is the best answer that the students gave.
The answer is <span>a. most living organisms can survive in environments with several different temperature and salinity levels.
</span>Aquatic plants and animals depend on dissolved oxygen for respiration. The other abiotic factors that impact their life in an aquatic ecosystem are temperature, salinity, and flow and they determine the quality of their life. <u>It is not true that most living organisms can survive in environments with several different temperature and salinity levels.</u> On the contrary, a few species can live in <span>environments with several different temperature and salinity levels, for example, some bacteria. The most organism can survive in a specific range of abiotic factors.</span>
Nowadays, that theory is rejected. Friedrich Wohler was able to synthesize urea from cyanic acid and ammonium, both being inorganic matter. <---This disproves the theory of vitalism.
False
their legs were made form the spine of stingrays and they were used to ward of bad storms.
