There are two main groups of muscles, the quadriceps and the hamstrings, as well as a small muscle behind the knee (popliteus). The other muscles closely linked are the two calf muscles, which control how the ankle moves as well as the knee.
If we recall that the unit of time is âthe Day,â this value represents 1-1/3 days of time. Since there are 24 hours in a day, converting to hours is a simple multiplication 24 * 1.3333 = or 32 hours. (24 * 4/3 to be more precise). Finding the number of hours between two date/times is simple, just subtract the start date/time from the end date/time and multiply the result by 24 hours.
Units, credits, and contact hours. TCNJ courses are measured in âunits.â Each unit is worth four âcredits,â as most US institutions measure their courses in credits, or âcredit hours.â The conventional rule of thumb is that one US credit is equal to fifteen âcontact hoursâ spent in a classroom or a laboratory.
