Answer: China and Brazil both use hydropower and are both two of the top countries in the world using renewable energies to power their nations.
Explanation: With china in first place and brazil in third, these two countries are among the top three nations who produce the most renewable energy, and they do this primarily with hydropower which harnesses energy from water currents and converts it into electricity.
Answer:
By designing an experiment where the temperature on the thermometer is measured after a chosen (same) time interval when the thermometer is wrapped with the different materials and placed in the freezer
Explanation:
Experimental design
Materials given: freezer, a thermometer, samples of materials
setup:
1. The freezer is put on and made to remain at a particular temperature, mimicking the winter season.
2. Next, different materials for the coat design with equal dimensions are used to rap the thermometer whose initial temperature has been recorded in the same pattern and the thermometer is placed in the freezer and left for a certain time, which is made constant for the different materials.
3. after the time, the final temperature on the thermometer is recorded.
Result interpretation
The temperature is expected to drop after the time in the freezer, but the material with the smaller change (drop) in temperature indicates that it traps more heat hence is the best material for designing a winter coat
independent variables: type of material used
dependent variables: temperature on the thermometer
control variables: time, dimensions of materials, temperature of freezer, pattern of wrapping.
It is true that there must be equipoise in order to justify conducting a clinical trial. They need first to have a equipoise so that they will justify conducting a clinical trial. Clinical trial is a research about whether the medical treatment or strategy is acceptance or safe and effective for human beings. The answer is True.
Autotrophs make their own food using energy from photosynthesis.
<u>The autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into glucose. </u>
