The machine is plugged into an electrical source, which gets the motor's wheel spinning. The machine is then unplugged and the wheel keeps spinning under its own inertia. Then electrical energy is extracted from the spinning wheel
During photosynthesis, solar/light energy from the sun is transformed into C6H12O6, or glucose (chemical energy). Photosynthesis is defined as the process by which green plants and some other organisms use sunlight to synthesize foods (glucose) from carbon dioxide (CO2) and water (H20). Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen (O2) and glucose.
Answer:
A theory is the most logical explanation of events that occur in nature. The explanation often results from the use of the scientific method. First, a problem must be stated. Then, after gathering information, a hypothesis, or logical solution, is formed. The solution is then tested in an experiment. The factor that is tested in an experiment is called the variable. This factor is not contained in the control setup. Sometimes principles of chemistry, the study of how substances change and combine, are involved in experiments. At other times, principles of physics are instead.
The metric system is used for all measurements in science. Some basic units in this system are the liter for volume, the kilogram for mass, the degree Celsius for temperature, and the meter for length. Sometimes, the density of a substance, or its mass per unit volume must be measured. If dimensional analysis is needed, a conversion factor must be used.
Explanation:
Answer:
39.82 %
Explanation:
Proteins and carbohydrates provide 4 calories per gram. On the other hand, fats provide 9 calories.
We can first calculate the calories of protein + carbohydrates:
(30g + 4g) x 4 = 136 calories
And we must calculate the calories provided by fat:
10g x 9 = 90 calories
Now to get the percentage we must see how many calories the dessert has in total:
136 + 90 = 226 cal
This represents 100% of calories. And now we need to find out how much 90 calories are from the total.
226 cal -----> 100%
90 cal ------> X
(90 x 100) / 226 = 39.82 %
