Correct answer is A
Note: T = 273 + θ
θ = 45°
T = 273 + 45
= 318K
Micrometer screw gauge
Vernier Caliper
Meter rule
None of the instrument
Correct answer is B
Vernier calliper is used to measure the internal and external diameter of an object
e = M.A/V.R × 100 %
M.A = E.V.R
V.R = 1 ÷ sin θ M.A
M.A = 1/E × 100%
Correct answer is A
The relationship between M.A, V.R, e and 100% can be written as
e = M.A/V.R × 100 %
i.e E/100 = M.A/V.R
= L ÷ E/x ÷ y = Ly/Ex
E/100 = Ly/Ex

Correct answer is B
J.J. Thompson discovered ELECTRONS
9.4m
7.5m
5.7m
6.9m
Correct answer is A
As object and image are usually at equal distance apart from the mirror /p>
Distance between Abioye (a) and hip image (I) = AI
i.e. AI = 4.7 + 47
= 9.4m
