You are conducting preliminary research for an energy company and your job is to compare nuclear energy and solar energy. You need to calculate how many solar panels will be needed (and the total area they will occupy) to substitute 1 kg of nuclear fuel. Here is what you know so far: when 235 g of pure uranium reacts in a nuclear reactor, the mass loss is 0.00846 g. 1 kg of nuclear fuel contains 5% pure U-235. Each solar panel produces 5000W, the solar irradiance in the region is 220 W/m2 with an availability of 5 hr per day, and the efficiency of the solar panels is 25%.

Waves are used in many practical applications to support work, entertainment, and health. one example is the use of ultrasound imaging to safely track the development of a growing fetus. what is a specific example of a practical application of waves in medicine, entertainment, safety, or other fields? provide a brief explanation of how the properties of waves are useful to that application.

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.

You can estimate the degree to which a bond between two atoms is ionic or covalent by calculating the
