NECO Physics Practical Questions and Answers 2021. Checkout the NECO Examination Physics Practical 2021 Questions and Answers today. Earlier on we share with you the physics practical specimen as released by the National examination council. We understand that most science students find it difficult when it comes to practical. But the truth is that you can not run away from it. For you to have good NECO result in  Physics examination, you are required to pass the NECO practical physics examination.

In this page, we are going to share with you the Physics Practical question paper 2021 and the answers. The physics practical questions usually comprise of  questions from: Optics, Electricity and Mechanics.

### NECO Physics Practical 2021 Questions i. You have been provided with a retort stand, clamp and boss. a set of masses, a spiral spring, stop watch, split cork and other necessary  apparatus. use the  diagram above as a guide, carry out the following instructions

ii. Suspend the spiral spring vertically as shown in the diagram

iii. suspend a mass hanger on the free end of the spiral spring and add a mass m=50.0g to the hanger. pull the hanger gently downwards and release to set it into vertical oscillations.

iv. Determine the time t for 20 complete oscillations

v. evaluate the period T, of the oscillation. Also evaluate T^2

vi. Repeat the procedure for four other values of m= 70, 90, 110 and 130g. in Each case, determine t and evaluate T and T^2. Tabulate your readings

vii. Plot a graph of T^ on the vertical axis against m on the horizontal axis.

viii. Determine the slope, s, of the graph and the intercept, l, on the vertical axis.

### NECO Physics Practical Question and Answers 2

the question is provided below as an attachment. This Physics question have  is the no 3 questions in the neco exam physics practical questions.  the complete questions is attached below. ### NECO Physics Practical 2021 Answers

Below is the answer to physics practical question 1 and 3 as released in the question papers.

### 1.    NECO Exam Physics Practical Questions and Answers 2021 Part 3  3a)
R ( N ) – | 2 .00 | | 4 .00 | | 6 .00 | | 8 .00 | | 10 .00 |
1 (A ) – | 2 .85 | | 2 .21 | | 2 .00 | | 1 .75 | | 1 .65 |
R ^ – 1 – | 1 .05 | | 0 .25 | | 0 .17 | | 0 .13 | | 0 .10 |

3bi )PRECAUTIONS
i)i ensured clean terminals
ii)i avioved zero error on the ammeter used
iii)i ensured tight connection of all wires
3bii)
ohm’s law states that the current flowing through a metallic conductor is proportional to its portential difference provided that physical condition is constant i.e V x I
3c)
slope(s) = DR^-1/DI = 0.25-0.10/2.21-1.65
=0.15/0.56
slope(s)=0.27
intercept c = -0.35
evaluation
1/5=1/0.27=3.70
evalution
1/C = 1/-0.35
=-2.86
