Astudent using a styrofoam cup as a calorimeter added a piece of metal to distilled water and stirred the mixture. a) the initial temperature of 50.0 g of water was 25°c b) the initial temperature of 20.0 g of metal was 100 °c c) the final temperature of the water and metal was 32.0° c which statement correctly describes the heat flow in calories? [hint: ignore heat gained or lost by the calorimeter. no calculations are needed to be performed]

a. the water lost 1360 calories of heat and the metal gained 140 calories of heat.

b. the water lost 350 calories of heat and the metal gained 350 calories of heat.

c. the water gained 350 calories of heat and the metal lost 350 calories of heat.

d. the water gained 1360 calories of heat and the metal lost 350 calories of heat.

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
