Elag for Review Scientists today are studying tidal power as an alternative energy source for generating electricity
Some scientists conclude that tidal power is a good alternative source of energy because it uses a natural process, does not rely on fossil fuels, and does not
release greenhouse gases. These scientists recommend building tidal power
plants around the United States in
locations with high tidal power potential.
Other scientists conclude that tidal power is not a good alternative energy source because tidal power plants can negatively impact the surrounding ecosystem by
killing marine animals, restricting fish migration, reducing the natural flow of water, and causing silt buildup in waterways. These scientists recommend not
building tidal power plants in U. S. waterways.
Both conclusions are based on valid data and scientific reasoning. How can both conclusions be valid?
ОА. The two groups of scientists believe different theories about the process of generating electricity
ОВ.
The two groups of scientists are looking at different specific aspects of the same scientific problem.
The two groups of scientists collect and analyze data about all types of possible alternative energy sources.
OD. The two groups of scientists are on opposite sides of the debate on whether the United States needs to find clean alternative energy sources.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error

girl imma just put my comment here because i need a couple point okurrttt

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
