Activity 4 Understanding the Sprint5. Compare the distance versus time graph with the bar graphof speed versus distance. a) When the distance versus time graph is curving earlyin the run, do the bars on the bar graph change inheight or are they fairly steady in height? What doesthis comparison mean? When the graph is climbing in astraight line, what is happening to the heights of the barson the bar graph? What does this comparison mean?b) Someone said, "The slope, or steepness, of a distanceversus time graph at any instant is the speed at thatinstant." Do you believe this statement? Why or why not?c) Describe the slope, or steepness, of the distance versustime graph each second (1.00 s, 2.00 s, 3.00 s, and so on)during Lewis’s record run.

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
