9. Define Accuracy and Precision with an example.Accuracy is how close a value is to its true value.An example is how close an arrow gets to the bull's-eye center.Precision is how repeatable a measurement is. An example is how close a second arrow is to the first one (regardless of whether either is near the mark).

I dont understand how to do this Using your FBD, derive an expression for tan θ in terms of FCoulomb and Fgravity, whereθ is half of the angle between the two pieces of tape at the apex of the tent shape. Hint:r is the length of the side of a right triangle opposite angle θ, and L is the hypotenuse ofthis triangle.
1. A laser beam is aimed 15.95° above the horizontal at a mirror 11,648 m away. It glances off the mirror and continues for an additional 8570 m at 11.44° above the horizon until it hits its target. What is the resultant displacement of the beam to the target, angle and direction? Convert final answer in feet
I need help with this the data needed is in the 1st photo
Both parts plz. Please indicate Fx, Fy, Fz seperated with commas like the question asks.
Pls help me answer this with complete solution and please highlight the answers
Prescriptions for vision correction are given in units called diopters (D). Determine the meaning of that unit. Obtain information (perhaps by calling an optometrist or performing an internet search) on the minimum uncertainty with which corrections in diopters are determined and the accuracy with which corrective lenses can be produced. Discuss the sources of uncertainties in both the prescription and accuracy in the manufacture of lenses.
If two different theories describe experimental observations equally well, can one be said to be more valid than the other (assuming both use accepted rules of logic)?
I'm on my HW and am totally blanking here. Help would be great thanks!
Hi, Please pay attention to what the question is asking. It clearly states to draw a graph and to fit the best straight like through the data. Thanks in advance
I need help to find the calculation for the answer is 30 cm and 1.07 uN I need it step by step so i can understand how they got the answer for a) and B)
