1.
In this case we have a systematic error because the rule is worn
and produces incorrect results. This result can be corrected.
Answer: Systematic error.
2.
In this case we have a random error because the child's height cannot represent the average height, this value cannot be estimated.
Answer: Radom error
3.
The contribution of air resistance cannot be estimated. We have a random error.
Answer: Random error

I need help plz I. You masure the kength of a board with a ruler that is olde and has a wom -down end If you align the end of the board wih the end of the raler, wha type of uncettainty does the end of the ruler contribule to the measurement? A) Random B) Systematic 2· The average height of children in kindergarten th Wintipeg is fund by measuring the height ofone tandomily- selected child in every kindergarten class...
Using the addition and subtraction rule for propagation of uncertainties, select the expression for the uncertainty in the net force. Form: r = x ± y Rule: Δr = Δx + Δy Question 1 options: A) ΔFnet = ΔF1 - ΔF2 B) ΔFnet = ΔF1 + ΔF2 C) ΔFnet = Δx + Δy D) ΔFnet = 3 Question 2 (1 point) Saved If the results of the force measurements are F1 = (12.2 ± 0.9) N and F2 = (19.8...

ROGERS 20:20 97% a universityofmanitoba.desire2learn.com Question 2 (1 point) A student measures the diameter of a disk fifteen times with a ruler that has a smallest division of 1 mm. The average of the 15 measurements is 17.04667 cm and the sample standard deviation is 5.595063x10-3 cm. The correctly rounded-off uncertainty (don't use scientific notation) is cm and the correctly rounded off value is cm. D View hint for Question2 Question 3 (1 point) The diameter of...
need help asap!! thanks in advance A diving board has length of 1.8 m and a total mass of 65 kg. However, the mass is not uniformly distributed, so its center of mass is off center as shown in the diagram below. However, we know that the moment of inertia around the center of mass is 20 kg m². The board is fixed to rotate around its far left end. A support pushes up with a force of 750 N...

Consider a bar, of length 5.5 m, shown in the figure, being acted on by three forces. The magnitudes of the first two forces are 16 N and 29 N, and the first force is acting on the end of the bar at an angle of 29° as shown. Part (a) What is the torque, in newton-meters, due to F1 on this bar relative to the left end? Use a coordinate system with positive directed out of the screen. Part (b) What...
A diving board has length of 1.8 m and a total mass of 50 kg. However, the mass is not uniformly distributed, so its center of mass is off center as shown in the diagram below.
