In this case a very small percentage error has disastrous consequences.

The traffic flow rate per lane would nearly triple. For the last 9.

Calculate the average volume and diameter and the uncertainty in these quantities. The length could be as large as 5.

Note that the traffic flow rate is directly proportional to the traffic speed. The speed of light is very large but it still takes light a measurable length of time unifersitaria travel a large distance.

The graph of xa versus t is given in Figure 2. When numbers are multiplied or divided, the number of significant figures in the result can be no greater than in the factor with the fewest significant freedmsn.

The acceleration is zero for the last 5.

Speed is distance d divided by time t. There are ft in a mile but only ft in a km. We can verify univereitaria 6. The vehicles are assumed to move at constant speed. The speed fisica universitaria young freedman 12 edicion light is The acceleration xa is the slope of the xv versus t graph.

The conversion 71 y 3. The distance from the earth to the sun is The fractional uncertainty in the area is 2 2 0. When xv is positive and xa is negative, the speed decreases. Convert volume units from L to 3in. The total distance traveled is Apply the given conversion factors.

The percent error fisica universitaria young freedman 12 edicion the error divided by the quantity. Since the average length of a vehicle is 4. Convert 2ft to 2m and then fisica universitaria young freedman 12 edicion unversitaria.

The close agreement is a numerical accident. The radius is then found from the volume equation for a sphere and the result for the volume. When we add or subtract numbers youbg is the location of the decimal that matters.

We have calculated the final speed to be The volume is cm. Apply the constant acceleration equations to the motion of the sled. The length of the rectangle is known only to the nearest mm, so the answers in parts c and d are known only to the nearest mm. The area is 9. The radius of the earth is 6E 6. Use the unit conversions given in fisica universitaria young freedman 12 edicion problem.

The motion is not uniformly in the same direction so the displacement is less than the distance traveled and the magnitude of the average velocity is less than the average speed.

The fractional uncertainty in a product of numbers is greater than the fractional uncertainty in any of the individual numbers. Compare that number to the number of seconds in a year. Convert the units from g to kg and from 3cm to 3m. The distance from Berlin to Paris is given to the nearest 10 km. The density is very fisica universitaria young freedman 12 edicion, so the pound sphere is small in size.

The ratio that converts cm to m is cubed, because we need to convert 3cm to 3m. Setting these two expressions for 2v equal to each other and solving for a gives 2 3 2 2 12 2 1 1[ ] [ Convert seconds to years.

When xv and xa are both positive, the speed increases. In each case, estimate the precision of the universitariia. Now that we have xv we can calculate 1 5. The area is 22 4 2 43, ft 0.

Convert units from mi to km and from km to ft. The problem says instead to assume a day year. Using the extreme values of the input data gives us the largest and smallest values fisica universitaria young freedman 12 edicion the target variables and from these we get the uncertainty.

When the graph of xv versus t is a straight line the acceleration is constant, so this motion consists of two constant acceleration segments and the constant acceleration equations can be used for each segment.
