Using an oscilloscope, it can be observed that the pitch of a sound is directly related to a sound wave’s frequency while the volume is directly related to a sound wave’s amplitude. the change shown in the illustration suggests that the a) pitch is increasing. b) pitch is decreasing. c) volume is increasing. d) volume is decreasing.

Reaction rate depends on how many molecules are coming into contact with each other with enough energy to react. increasing the temperature of the reactants will increase -

Amap that uses a range of colors and shading to represent the elevation, depth, or landscape of specific features on earth is a/an map.

To find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? a) when more work was done, the couch was moved the same distance. b) when more work was done, the couch was moved less. c) when more work was done, the couch was moved further. d) when more work was done, the couch wasn't moved at all.
