Mathematically, relation between force, area and pressure is given by...
Pressure = force / area
hence, pressure is directly proportional to force but inversely proportional to area.
Answer: True!
Explanation: The force is proportional to the square of the distance between 2 point masses
Answer: Temperature and humidity are the two characteristics used to classify air masses.
Explanation:
Answer:
Part A: 16.1 V
Part B: 20.5 V
Part C: 21.5%
Explanation:
The voltmeter is in parallel with the 4.5-kΩ resistor and the combination is in series with the 6.5-kΩ resistor. The equivalent resistance of the parallel combination is given as


Part A
The voltmeter reading is the potential difference across the parallel combination. This is found by using the voltage-divider rule.

Part B
Without the voltmeter, the potential difference across the 4.5-kΩ resistor is found using the same rule as above:

Part C
The error in % is given by
