Electrical power generated by a particular wind turbine is given by w=(7L^2s^3)/(32) where W is power in watts, Lis the length of a turbine blade in feet, and S is the speed of the wind in miles per hour. How many watts are generated by a wind turbine with a blade length of 20 feet if the wind has a speed of 4 miles per hour? The power generated by the wind turbine is square square

Hubble's Law has led physicists and astronomers to the hypothesis that the universe is expanding. True False

Newton determined that the force of gravity on an object is proportional to its mass causing its mass to be canceled out (Newton's second law) and resulting in a constant acceleration. If the laws of physics are universal, then Newton should be able to apply his discoveries about gravity on Earth to the motion of the planets in our Solar System. Newton's third law says that for every force there is an equal reaction force in the opposite direction. What does this imply about the force of gravity associated with a person standing on the Earth? Choose one: A. The force of gravity on the person cancels out to zero. B. The Earth's gravity pulls downward on the person but also pushes upward on them. C. The Earth's gravity pulls downward on the person, and the person's gravity pulls upward on the Earth. D. There is twice as much gravitational force on the person than there would be if it weren't for Newton's third law.
