Pls pls pls help im begging

1. An incline plane is a flat plan put at a positive angle with the ground (assuming the ground is horizontal)

2. Work equals force times distance. And since the hypotenuse of a triangle (the ramp) is longer than the opposite side (equivalent to lifting an object vertically), the increased distance decreases the force needed to do a certain amount of work.

3. We usually use incline planes to elevate large objects.  Since it takes less force to move certain things up inclines rather than picking them up, it is much simpler to move an object up an incline.

4. You could decrease the force by making the plane's angle with the ground smaller.

5. I don't know; I wasn't in your class :)

6. Ramps, wheelchair entrances, inclined rooves etc.

7. No. A plane has to be relatively flat; therefore stairs are neither a plane, nor an inclined plane.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

can you list the answers so i can answer
