Bianca is standing at x =600m. firecracker 1, at the origin, and firecracker 2, at x =900m, explode simultaneously. the flash from firecracker 1 reaches bianca's eye at 4.0 μs . part a at what time does she see the flash from firecracker 2?

Explanation:

Given

Bianca is at

i.e. distance between origin and Bianca is

time taken to reach Bianca eyes is

i.e. Cracker exploded at because it is observed at

Time taken by second cracker flash to reach Bianca eyes

Therefore it will be observed at

heats surface water up

  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.
