Question 1 Part a:
10.3° = 10.3 x (π / 180) [Degree x (π / 180)= rad]
10.3° = 0.180 rad

Question 1 Part b(i):
tan θ = 0.182 [Calculator work]

Question 1 Part b(ii):
% Error = 100 x [(0.182 - 0.180)/0.182]
% Error = 1.1%

one ond of the copper wire is stuck to the metre rule with the help of plasticine and a large number of turn of wire suppose x are wound around the rule such that each turn is touching the previous one the readings l1(start of the coil) and l2(end of the coil) are noted down in mm from the rule

the diameter of teh wire d can be found as following=l2-l1/x

this method gives an average value of the diameter of the write as it has bbeen calculated oout of the ciombined diameter of several similar wires put together side by side
hope it helps.
