A piston releases 18 J of heat into its surroundings while expanding from 0.0002 m2 to 0.0006 mº at a constant pressure of 1.0 x 105 Pa. What are the
correct values for heat and work for the piston?
A. Q = -18 J, W = +40 J
B. Q = +18 J, W = +40 J
C. Q = -18 J, W = -40 J
D. Q = +18 J, W = -40 J

  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.

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
