The radius of mercury (from the centerto just above the atmosphere)
is 2440km (2440103
m),and its mass is 0.31024
kg. an object is launched straight up from just above the atmosphere
ofmercury.
(a) what initial speed is needed so that when the object is farfrom
mercury its final speed is2000 m/s?

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
