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.

Simone is walking her dog on a leash. The dog is pulling with force of 34 N to the right and simone is pulling backward with a force of 16 N
