NECO Physics Essay Answers for Today 2022


(i)a printing press



Figure (step up transformer)










When a system is displaced, it encounters a net force in the same direction as the displacement.


When a system is displaced from equilibrium, it feels a net force in the same direction as the displacement. If it is displaced even little from its equilibrium position, it tends to accelerate away from it, whereas in neutral equilibrium, the system is unaffected by displacement from its original location.


(ii)Low centre of gravity

(ii)Large contact surface area


Velocity is a vector quantity with the SI unit of ms-1. It is defined as the rate of change in a body’s displacement.

No (3aii)

1. They both involve molecules escaping into the atmosphere.

2. They are both dependent on the liquid’s nature.

3. They are both affected by pressure.

4. They are both dependent on the surface area.

5. Both are reliant on impurities.




The body has the most kinetic energy when it is in equilibrium position B. As it approaches end points A and C. It comes to a complete halt before shifting course.


No (5a)

Both are derived quantities.


x-25/100-25 = 67-0/100-0

x-25/75 = 67/100

4 = 61*3 (x-25)

4x-100 = 201

4x = 201+100+100+100+100+100+100+100+100

301 = 4x

75.25 ohms = x = 301/4





A lens camera has a shallower depth of field than a pinhole camera.

No (7a)

– Amplification

16cm u u u u u u u u

v/u = m = 4

:. v =4u :. v =4u :. v =4

v = 416 = 64cm v = 416 = 64cm v = 416 = 64cm

Remember that 1/f = 1/u + 1/v

1/16 + 1/64 = 1/f

4+1/64 = 1/f

5/64 = 1/f

f = 64/5 = 12.8cm f = 64/5 = 12.8cm f = 64/5 = 1

No (8a)

The zinc atoms on the anode’s surface oxidize, which means they lose both of their valence electrons and become positively charged.




When the perceived power equals or exceeds the real power, the power factor of a circuit is unity.











(i)Viscosity; the force that exists between the layers of fluids; this force tends to slow the stone’s descent until it reaches terminal velocity.

(ii)weight; refers to the stone’s actual force in the liquid.

(iii)upthrust is the upward force experienced by responding objects in fluid as a result of area displacement.


A = 9 (molecular mass)

B = 6 (atomic mass)
