Physics: Measurement Flashcards
1
Q
Tension in Tube
A
P = T/r
P= Pressure Gradient T= Tension r= Radius
2
Q
Tension in a sphere
A
P = 2T/r
P= pressure Gradient T= Tension r= radius
3
Q
Work Done (Nm/ Joules)
A
= Force * Distance
4
Q
Work Done (Pressure) (Nm/ Joules)
A
Work Done = Pressure * Volume
5
Q
Work Done (velocity) (Nm/ Joules)
A
= 1/2 Mass * Velocity 2
6
Q
Work Done (Temperature) (Nm/ Joules)
A
= mass*specific heat capacity*temp change (in Kelvin)
7
Q
Relative Humidity
A
= Actual Vapour Pressure (usually H20)/ Saturated Vapour Pressure
8
Q
Beer-Lambert-Bouguer Law
A
Ii = I0*e-cal
Ii- initial light
I0- incident light
e- Euler’s number
c- Concentration
a- Molar extinction coefficient
l- length
