Answer:
What does a linear velocity graph tell us?
The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).
What is an acceleration time graph?
A graph that shows acceleration plotted against time for a particle moving in a straight line. ... The acceleration-time graph is the graph y=a(t), where the t-axis is horizontal and the y-axis is vertical with the positive direction upwards.
graph shows changes in velocity of a moving object over time. The slope of a velocity-time graph represents acceleration of the moving object.

<span>contractile vacuole
Contractile vacuoles are organelles that are responsible for excretion function. They perform osmoregulation which manages wastes, water and other needed materials in the cell. They are found in some prokaryoric organisms like the algae, protists, amoeba and other unicellular organisms.

The cause behind these changes is the that the temperature is changing while it is raining, so when it drops to 32 degrees F or below, it is snow. At 32 degrees F, it is sleet, and at higher than 32 degrees, it is going to be freezing rain.
Explanation:
Porosity depends on the size, shape, and mixture of grains and particles that compose soil and rock. For instance, small particles such as clays can compact more closely together, reducing the amount of porosity. However, larger particles such as sand and gravel will have more spaces available between them.
