The specific heat of liquid mercury is 140 J/kgC. When 1 kg of solid mercury at its melting point of -39C is placed in a 0.5 kg aluminum calorimeter filled with 1.2 kg of water of temperature 20C, the mercury melts and the final temperature of the combination is 16.5 C. What is latent heat of mercury

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

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."

the answer would be   dignified - apex

  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.
