While a roofer is working on a roof that slants at 36° above the horizontal, he accidentally nudges his 85.0-n toolbox, causing it to start sliding downward from rest. if it starts 4.25 m from the lower edge of the roof, how fast will the toolbox be mov- ing just as it reaches the edge of the roof if the kinetic friction force on it is 22.0 n?

What is the rate of change in a objects position?

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!

When electrons are added to the outermost shell of a carbon atom, it forms--an anion that has a larger anion that has a smaller cation that has a larger cation that has a smaller radius.
