What is on the x-axis of a speed graph

What happens to the frequency and pitch of sound if the object making the sound moves away from you?

If 10 calories of energy are added to 2 grams of ice at - 30° C, calculate the final temperature of the ice. (Notice that the specific heat of ice is different from that of water.) T. F = -20° C -30° C 30° C 40° C

As temperature increases, the possible total humidity a. increases. b. decreases. c. increases and then decreases. d. remains the same.

Which changes would cause an increase in the resistance of a wire? Check all that apply. increasing its temperature decreasing its temperature using a longer wire using a shorter wire using a thicker wire using a thinner wire
