The lower case letter represents the recessive allele.
Moles = mass / molar mass
molar mass of O2 is 32
therefore moles = 72/32
= 2.25 moles
The answer is; A
By using a spring and determining the tension applied on the string by the car, it is possible to deduce the force. Determine the spring's initial tension as well as spring rate and working loads;
Rate = (Load – Initial Tension) ÷ Travel
k = (L – IT) ÷ T
