2018 Nov/Dec Neco Gce Physics Practical Answers And Questions Out
2018 NECO GCE Physics Practical Answer & Questions Released.
The Neco Gce Physics practical questions has been released at schools for exam preparations. The NECO GCE Physics practical answers and calculations is provided here.
The Neco GCE physics practical is usually divided into 3 questions (comprising of Mechanics, Waves and Electricity) with a few other general knowledge calculations added.
Here is a sample of the Neco gce physics practical answers and solutions from Neco physics past questions;
neco physics practical answer
(a) You have been provided with a beaker, a set of masses and other necessary apparatus.
i. Measure and record the internal diameter D of the beaker
ii. Pour some water into the beaker so that it is about half full Measure and record the depth d0 of the water.
iii. Suspend a mass M = 50g on the clamp of a retort stand.
Immerse the mass completely into the water as shown in the diagram above.
iv. Measure and record the new depth di of the water
v. Evaluate d = di – d0
vi. Repeat the procedure foe values of M = 100g, 15og, 200g and 250g
vii. In each case measure and record di and also evaluate d = di- do
viii. Tabulate your reading
ix. Plot a graph with M on the vertical anti and d on the horizontal axis
x. Deter mine the slope, s, of the graph
xi. Evaluate k=4s/PiD2 (Take Pi=22/7)
xii. State two precautions taken to ensure accurate results
(b) i. Define relative density of a body.
ii. An object weighs 2.7 N in air and 1.2 N when completely immersed in water Calculate the relative density of the body.
