Please , explain to me on how do you calculate to get the answers on the following questions? Answers are below.
Q1 : The diameter of a wire is measured as 1.2 +/- 0.1 mm. The length of the wire is 73.0 +/- 0.5 cm.
Determine the uncertainty in the volume.
Q2: A dart player throws a dart that hits the dartboard at the same height as that from a distance of 3.0 m from the board and takes 0.25 s to reach the board.
Calculate...
a) the maximum height reached by the dart
b) the horizontal speed of the dart
c) the vertical speed of the dart when it reaches the dartboard.
Ans:
Q1 - > 2.3% or absolute uncertainty = 0.2 x 10^3 m^3
Q2 - > (a) 0.31m (b) 12ms^-1 (c) 2.5 ms^1
