There are two open cans of soda on the table. one can was just taken from the refrigerator and the other was taken from the cupboard. upon opening the cans, which one loses carbon dioxide more quickly and why?

a.
the can from the refrigerator, because it is colder and gases are less soluble in colder temperatures
b.
the can from the refrigerator, because it is colder and gases are more soluble in colder temperatures
c.
the can from the cupboard, because it is warmer and gases are less soluble in warmer temperatures
d.
neither, because the solubility of gases is affected only by pressure and not temperature

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.

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

Which fact supports the conclusion that there will be fewer farm managers in the future? a) a farmer manager’s duties vary by the type of farm. b) farm technology is replacing some administrative jobs c) farm managers often need experience but not education. d) administrative duties include budgeting and training staff.
