Based on the kinetic theory of matter, which statement is incorrect? 1. At temperatures above absolute zero, all matter has energy and the particles are moving.

2. Liquids have a variable shape and fixed volume. The particles of a liquid slide past each other .

3. Gases have a variable shape and volume. The particles of gases move quickly

4.Solids have a fixed shape and volume. The particles of a solid do not move.

the answer to this question is 60 n

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."

wavelength divides in half and speed stays the same.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
