Two physics professors challenge each other to a 100 m race across a football field. the loser will grade the winner’s lab reports for a month. dr. nelson runs the race is 10.40s. dr. bay runs the first 25.0 m with an average speed of 10.0 m/s, he next 50.0 m with an average speed of 9.50 m/s, and the last 25.0 m with an average speed of 11.1 m/s. who is the winner?

Why does the input force have to be greater than the force needed to lift the bale?

How many molecules are present in 3 mols of silicon dioxide (sio2)?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
