The answer to this is D. All of the given examples can be converted from chemical energy to mechanical energy. Human beings usually need sugar and other types of food in order to become energized. Once they become energized, this can be transformed into mechanical energy that will allow human...Read More
HRV stands for Heat Recovery Ventilation. HRV works by removing stagnant air from a room that has higher humidity. It is commonly used in rooms that accommodate many rooms. It gives fresh outdoor air into the atmosphere. The heat recovery warms the incoming fresh air as the state air is...Read More
Every day, the demand for energy keeps on growing as the population and usage of electricity increase to power our homes and gadgets. Sadly, most energy that we consume today is not renewable though there is an effort to use solar and hydro energy to sustain the people widely. Two of the most...Read More
In Physics coupling occurs when the energy released by an exergonic reaction is used to drive an endergonic reaction. Exergonic reactions are reactions that lose energy as the process takes place while endergonic reactions are reactions that require energy to be driven.

The correct answer to this question is D, Becomes 16 times to that of the initial. To find kinetic energy, we would use the equation K = ½mu2. The initial velocity is u and based off the question, and the final speed becomes v = 4u. Knowing this information, we can fill in the equation,...Read More
Reflection is a part of science which can best be described as waves in which they have changed directions. The most common place to find this reflection is in mirrors or in a lake. In light, absorption is also known as electromagnetic radiation.
