Question
Answer the following questions accurately using full sentences. Your responses may be handwritten or typed (preferred) and attached to the pre-lab. Why do you need to know and record the temperature of the water in Activity 1? Explain why the density unit of g/cm^3 is equivalent to g/mL. Explain the purpose of the calibration graph. Look at the graph below and state in words the relationship between the applied force and the voltage experienced by the system. Visually interpolate to determine the approximate voltage when a force of 160 lbs is applied. What is the approximate applied force if the system exhibits a voltage of 0.75 units? How could these values be determined exactly?Explanation / Answer
1.
To answer this I need to know which experiment you are talking about
2.
g/cm^3 is same as g/mL because 1 cm^3 = 1mL
3.
you have already found the relation between y and x
y = 0.0118x + 0.1833
Here y is volatge, V and x is force F
so,
V = 0.0118F + 0.1833 <---Answer
when F = 160 lbs,
V = 0.0118F + 0.1833
V = 0.0118*160 + 0.1833
=2.07 V <-----Answer
at V = 0.75 unit
V = 0.0118F + 0.1833
0.75 = 0.0118F + 0.1833
F = 48 lbs <---Answer
