Answer:
C. 500 J
Explanation:
Given;
potential energy of the kids at the top of the trampoline, P.E = 1,000 J
⇒At the top of the trampoline, the kids have only potential energy.
⇒On half way down, the kids have both kinetic energy and potential energy.
⇒At the bottom of the trampoline, the kids have only kinetic energy.
Based on the statements above, the kinetic energy of the kids half way down is calculate as;
P.E + K.E = 1000 J
Base on law of conservation of energy, P.E = K.E
2 K.E = 1000 J
K.E = ¹/₂ x 1000 J
K.E = 500 J.
The appropriate answer is d. gases such as carbon dioxide and methane. These gases are known as greenhouse gases and they trap heat in the form of infrared radiation. Without this effect the earth would be 30 degrees cooler. Nitrogen dioxide and sulfur dioxide are examples of other greenhouse gases. An increase in the volume of these gases is responsible for present day global warming that is causing a change in the the earth's climate.
Answer:
Nutrition
Explanation:
Nutrition is the study of diet and its relation to health. Those that specialize in this type of study are dietitians. It is considered a science that deals with what we eat and how it affects our bodies. They study things like how deficiencies, excesses or imbalances of certain foods or food components (i.e. minerals, vitamins, nutrients, etc.) relate to overall health as the state of any of these may result in a disorder or disease. They not only determine cause but they also help in developing interventions to help treat patients with different diet-related diseases; and help in developing preventive measures.
The role of nutrition as a study is imperative because essentially, we are what we eat. What we consume on a regular basis contributes to the efficiency of the functions of our body. The food we eat can have an effect on the body not only in the organ level, but even on the cellular level, as our cells rely on the food we eat and drink for energy to function.
If your period of development in which your reproductive system matures and your sex hormones increases its called puberty
If their data they collected from their experiment proved their hypothesis correct, then yes, their supported hypothesis can be called a scientific theory.
