People in the United States know that water boils at 212F. In Europe, people know that water boils at 100 C. Is the water in the U. S. Different than the water in Europe? What explains the two different temperatures?

Three forces are exerted on an object placed on a slope in the figure. The forces are measured in Newton (N). 1. Assuming that forces are vectors, what is the component of the net force F⃗net=F⃗1+F⃗2+F⃗3 parallel to the slope? 2.

Which is true? The net potential change around a closed circuit loop is zero. The net potential change counterclockwise around a closed circuit loop is positive. The net potential change clockwise around a closed circuit loop is positive.

What is the composition of a typical football field and where is the "end zone?"?

As the phase difference between two interfering waves changes from 180° to 0°, the amplitude of the resultant wave A) Decreases B) Increases C) Remains the same

What is the momentum of a 2 kg ball traveling at 2m/s

A constant force is exerted for a short distance on a block of mass that is initially at rest on a horizontal frictionless plane. This force gives the block a certain final speed v.

A football quarterback is moving straight backward at a speed of 3.00 m/s when he throws a pass to a player 20.0 m straight downfield. (a) if the ball is thrown at an angle of 25.
