The option D of the following displacement graphs matches the simulation snapshot.
Explanation:
As per the given information through the graph.
By convention, a displacement to the right is considered positive, and a displacement to the left is considered negative. In the tube, the red divider is displaced to the left of its original position (marked by the red dot), and the green divider is displaced to the right of its original position (marked by a green dot).
The only graph that shows a negative displacement of the red divider and a positive displacement of the green divider is graph D.
Therefore option D matches the simulation snapshot in the displacement graphs.
Good morning dear...
Have a beautiful and joyful day ahead.
Answer:
Specific Heat
Explanation:
It is the definition of is Specific Heat which is the amount of heat (calories) per unit mass (gram) required to raise the temperature (1°C)
Its unit is calories/g °C
Answer: When quantities have the same relative size. In other words they have the same ratio corresponding in size or amount to something else.
Explanation: Example: "A rope's length and weight are in proportion."
Example: "The punishment should be proportional to the crime"
Givens
=====
Ti = 92.8 oC = 92.8 + 273 = 365.8
T2 = 0.4 oC = 0.4 + 273 = 273.4
Vi = 1.54 mL
Vf = ?????
Formula
======
Vi/Ti = Vf / Tf
1.54 / 365.8 = Vf / 273.4
Calculations
=========
1.54 * 273.4 / 355.8 = Vf
vf = 1.15 mL
Comment
=======
if your teacher is concerned about sig digs, the answer is 1 mL. I'm not sure how to show that it is 1 sig dig. You can ask about this.
