Two identical masses are moving down a slope. One mass is traveling twice as fast as the other mass. how does the kinetic energy
nlexa [21]
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.

Which is a major by product of respiration? Choose the correct answer.
lana66690 [7]

Answer:

This question is incomplete as it lacks options, however, it can be answered. The answer is:

CARBON DIOXIDE (CO2)

Explanation:

Cellular respiration is the process by which glucose is broken down in an organism's cell to release energy. Although the process involves series of reactions, however, the general equation is as follows;

C6H12O6 + 6O2 ➡ 6CO2 + 6H2O + energy

Based on the above equation, the inputs are glucose and oxygen while the outputs are carbon dioxide and water. Carbon dioxide (CO2) is the major byproduct of the respiration process.
