Hurry when using a calorimeter, the initial temperature of a metal is 70.4c. the initial temperature of the water is 23.6c. at the end of the experiment, the final equilibrium temperature of the water is 29.8c. what is the final temperature of the metal? c what is the temperature change of the water? c what is the temperature change of the metal? c

Two point charges are on the y axis. a 3.90-µc charge is located at y = 1.25 cm, and a -2.4-µc charge is located at y = −1.80 cm. (a) find the total electric potential at the origin. v (b) find the total electric potential at the point whose coordinates are (1.50 cm, 0). v

Suppose a comet has an orbital period of 309.1 years around the sun. what is it’s average distance from the sun?

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
