PLS PLS PLS PLS HELP ME I WILL FAIL AND IT'S FINALS Charged rubber rods are placed near a neutral conducting sphere, causing a redistribution of charge on the spheres. The diagrams below depict the distribution of that charge. If the rubber rod were to touch the sphere, make a prediction about what the net charge for each object might be.
The rod starts with a*select* -*positive, negative, neutral*
charge and the sphere starts with a [ Select ]- *positive, negative, neutral*
charge. After the rod touches the sphere, charge will transfer from the *rod or sphere*
to the *rod or sphere*

How many milliliters of water at 23 °c with a density of 1.00 g/ml must be mixed with 180 ml (about 6 oz) of coffee at 95 °c so that the resulting combination will have a temperature of 60 °c? assume that coffee and water have the same density and the same specific heat. how much will the temperature of a cup (180 g) of coffee at 95 °c be reduced when a 45 g silver spoon (specific heat 0.24 j/g °c) at 25 °c is placed in the coffee and the two are allowed to reach the same temperature? assume that the coffee has the same density and specific heat as water. a 45-g aluminum spoon (specific heat 0.88 j/g °c) at 24 °c is placed in 180 ml (180 g) of coffee at 85 °c and the temperature of the two become equal. (a) what is the final temperature when the two become equal? assume that coffee has the same specific heat as water. (b) the first time a student solved this problem she got an answer of 88 °c. explain why this is clearly an incorrect answer.
