Circular Lab
physics lab Question easy….?
Q.1
An object moving along a circular path completes 3 revolutions every minute. What is the period of the object?
Choose one answer.
a. 3 rpm
b. 20 s
c. 3 minutes
d. 0.33 seconds
Q.2
A student repeatedly measures the time taken by an object to cover a certain distance and obtains the following data:
t1 = 2.432 s, t2 = 2.398 s, t3 = 2.402 s, t4 = 2.412 s, t5 = 2.424 s
The instrument uncertainty is 0.001 s
What should the student report as the absolute uncertainty in the measurement? (HINT: The absolute uncertainty can be given by either the instrument uncertainty or the standard error in the measurements)
Q1.
Period is the amount of time it takes to complete 1 revolution. I’m sure you just don’t know the definition.
Q2.
According to hint there are two right answers:
One is just +/- 0.001s
The other one can be found by doing the following:
1. calculate the average
2. calculate the square of each (tn-average)
3. add them, and divide the whole thing by 5
4. square root the whole thing to get the final answer.
sqrt( ((2.342-a)^2 + (2.398-a)^2+……..)/5) )

Air Synergy Labs #43912 Circular Vortex Valve Efficiency Booster $69.95 The Vortex Valve changes the air flow into the same shape as the opening (intake valve) it must go through to mix with the fuel. The resulting vortex causes the air to flow more effectively through the intake system, through the engine manifold to the pistons. The result is greater airflow into the combustion chamber and more complete combustion – in the engine where you can benefit from the powe… |
