Unless already stated? My math teacher went into an explantion but I didn't really get it, maybe you people can explain better?

Also, what does the "laun" button mean on my calculator (it looks like "Ln")? My math teacher said it is has something to do with logs but I don't know exactly.

I have been treating my dry skin on my hand with a solution of 1 cup epsom salt to one gallon of very hot water an then soaking it for 15 minutes and it seems to be working really well. I Was just curious that if I added peroxide to the solution would it be able to kill off what ever is causing the dry skin to begin with.

Of all the articles and books I have read I do not recall ever seeing anything about the Lutz children. I know George and Kathy are deceased, I am just suprised their kids have never said much regarding the story.

A chair of mass 8.00 kg is sitting on the horizontal floor; the floor is not frictionless. You push on the chair with a force 35N that is directed at an angle of 35.0 below the horizontal and the chair slides along the floor.

Use Newton's laws to calculate the normal force that the floor exerts on the chair.
Take free fall acceleration to be 9.80 m/s^2.
