A student pushes a 10.92 kg block up a 67.7 degree incline and pushes with a 229.32 N force. The coefficient of kinetic friction between the surface of the block and the incline is 0.02. What acceleration does the block experience?

I have no idea, but I can't find any no matter what database I use. Any help would be greatly appreciated!

When 1.45x10^4 joules of energy is lost from 4.56 kg of a substance, the temperature decreases from 94ºC to 66ºC. The specific heat of this unknown substance is what?(J/kg·ºC).

A horizontal force of 805 N is needed to drag a crate across a horizontal floor with a constant speed. You drag the crate using a rope held at an angle of 32 degrees above horizontal. What is the force you exerted on the rope? (I thought the answer was 671.5, but that was not correct)

I have absolutely no idea, and I feel as if I have tried everything possible. Any help would be great!

Sorry, I have absolutely no clue how to solve this. Any information on how to would be greatly appreciated!

My parents are kind of crazy and don't let me play any kind of M rated games despite me being old enough to get a job and drive. I have most of the obvious ones like Uncharted, Little Big Planet, Ratchet and Clank, Sly Cooper, and some other obvious ones. Are there any good games that not a lot of people know about, because I have heard of most of the popular ones that I mentioned. Any suggestions would be great!

I can't find any search bar or anything like that. Definitely a terribly designed site.

How do you dilute a 200M solution to 45M if there is 24L in the original solution?

I really hate doing these, but I am not really sure about the results of this. Any help would be greatly appreciated. :)

Here are my specs:

Intel HD 4400 graphics

i5 4400u processor

6gb ddr3 ram

I have looked at sites that say both it can and it can't and most of the time they are wrong. I have played games like CoD and Borderlands that can run on my computer, even though some sites say it can't or is at a very low framerate. Any help would be great!

I normally don't do these things, but I have read the whole book and searched online for hours trying to find symbols for this, but I don't find many that are actually draw able. I already did fire and yams, but I don't know what to do for the 3rd one. Any help would be great!
