A metal part is placed in a calorimeter containing 1.89 g of water. If the initial temperature of the water is 21°C, and the final temperature of the part and water 31°C, what is the amount of energy transferred as heat to the water (Cp = 4.186 J/g•°C)?

An object starts from rest at point f and speeds up continuously as it moves around an oval. a. choose a point about 1/8 th of the way around the oval from point f, and label it point g. draw a vector to represent the velocity of the object at point g. b. determine the change in velocity vector   between points f and g.

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.
