Answer:
A. Is the one that the experimenter manipulates directly
Explanation:
The independent variable is the one that is manipulated during an experiment by the experimenter.
The dependent variable is the one that is effected by the independent variable in an experiment.
Answer:
The value is the temperature of the air inside the tire
340.54 K
% of the original mass of air in the tire should be released 99.706 %
Explanation:
Initial gauge pressure = 2.7 atm
Absolute pressure at inlet
= 2.7 + 1 = 3.7 atm
Absolute pressure at outlet
= 3.2 + 1 = 4.2 atm
Temperature at inlet
= 300 K
(a) Volume of the system is constant so pressure is directly proportional to the temperature.


340.54 K
This is the value is the temperature of the air inside the tire
(b). Since volume of the tyre is constant & pressure reaches the original value.
From ideal gas equation P V = m R T
Since P , V & R is constant. So
m T = constant




value of the original mass of air in the tire should be released is

⇒ -0.99706
% of the original mass of air in the tire should be released 99.706 %.
The significant figures also known as the significant digits or precision of a number written in positional notation are digits that carry meaningful contributions to its measurements
The answer is , Conductance
Answer:power is equal in the three Scenarios
Explanation:
Power=work ➗ time
scenario A:
Power=120 ➗ 6
Power=20watts
Scenario B:
Power=160 ➗ 8
Power=20watts
Scenario C:
Power=work ➗ time
Power=200 ➗ 10
Power=20watts
Power is equal in the 3 scenarios
