Q5.
<span>The
answer is A. In thermodynamics, the first
law of conservation states that energy can never be destroyed or created but
can only be transformed from one form to another. Therefore part of the
electric energy was converted to light energy while the other dissipated as
heat. However, the summation of the energy
of these tow outputs in joules remains
the same as initial electric energy.

Q6
<span>The answer is B. This is because
the water in the dam is used to turn turbines hence this form of energy is mechanical energy. As the turbines turn, they
turn electromagnets that convert the mechanical energy into electrical energy</span>
<h3><u>Answer;</u></h3>
- Catabolism is the process in which complex substances are broken down, yielding a net output of energy
- Metabolism is an integrated system in which many of the same reactions participate in degradative (catabolic) and biosynthetic (anabolic) pathways.
<h3><u>Explanation</u>;</h3>
- Metabolism is the chemical processes occurring within a living cell or organism that are necessary for the maintenance of life. In metabolism some substances are broken down to yield energy for vital processes while other substances, necessary for life, are synthesized.
- Catabolism is the metabolic breakdown of complex molecules into simpler ones, resulting in a release of energy. These reactions are exothermic.
- Anabolism involves the synthesis of polymeric biomolecules and complex lipids from monomers such as fatty acids and nucleotides. Anabolic reactions are endothermic.
Answer:
Oxygen and nitrogen
Explanation:
Oxygen and nitrogen are very electronegative than any other element in the periodic table hence they have more tendency to attract an electron towards itself
Answer:
Mass
Explanation:
Mass is defined as the amount of matter in a substance. It is usually measured by balances such as the beam balance and scales. It is measured in grams or kilograms depending on the size of the body.
The process of Rock formation involves how a rock is formed which is usually by sedimentation or cooling of magma in volcanic eruptions. In rock formation study,the geologist measures the mass of the rock which enables knowledge of the amount of matter in the rock. This is be used to determine the weight of the rock and the rock type and properties.
