A piston releases 18 J of heat into it’s surroundings while expanding from 0.0002 m3 to 0.0006 m3 at a constant pressure of 1.0 x 10 5 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

Because the sun is the biggest and if the sun orbits the earth we will be dead probably

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.

  the answer is don't know.

connectedness in handwriting analysis is a useful tool in establishing the writer’s method of thinking and its perception in where he/she fits in to the environment around him in the social sense. in addition, the more connected the writing of an individual, the more he/she is flexible and single minded.
