So there's a bunch of ways Direct link to 1140858's post Its not that they're bad , Posted a year ago. If you are redistributing all or part of this book in a print format, Legal. So let's just think about some Consequently, youll need a minus sign that you might not have expected. And they also ask $2 for that much cashews, that would be an incredible deal. . Which graph best represents the relationship between the elastic potential energy stored in a spring and its elongation from equilibrium? The higher the curve at a given speed, the more molecules travel at that speed. A lightweight object and a heavy object are sliding with equal speeds along a level frictionless surface. I'm left with k is equal to 2/5. Limestone and calcite are valuable natural resources. Let's do another one Now, if x increases . Which pair of graphs represent the correct relationship between displacement and the velocity of a moving object? So we had two points, Why am I still doing this I have no life really why would you say that don't know what the future holds. A great deal of information about a gas can be gleaned by considering the overall shape of the speed distribution curve. Watch the video again and pay attention to what Sal is doing. of 0.4 units in y. Direct link to alessandra's post Yes, you are correct. Note that m could also be eliminated. Observe that when the temperature goes up, the particles in a gas tend to move faster. The speed that corresponds to the peak of the curve is called the most probable speed. The diagram represents two pulses moving toward each other on a rope. The graph that best represents the relationship between work and time for the student's run up the stairs is. this point right over here, when our time is 2.5, we see that our distance driven is 200 km. Assume that no energy is lost to friction. If I divide both sides by 5, Now, let's think about what Did you expect the speed at the bottom of the slope to be the same as when the object fell straight down? The first two values are the row and column indices for the first element in the submatrix, and the third value is the number of the rows in the submatrix. The fraction of slow-moving molecules increases. Sal made, Posted 6 years ago. graph, and once again, we see it is a proportional relationship.
