ANSWER 3 ONLY.

Heat describes the transfer of thermal energy between molecules within a system and is measured in Joules. Heat measures how energy moves or flows. … Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or Rankine (R).

 9c. Linear expansivity is the fractional increase in length of a specimen of a solid, per unit rise in temperature. If a specimen increases in length from l1 to l2 when its temperature is raised θ°, then the expansivity (α) is given by l2 = l1(1 + αθ).*PHYSICS* 

(10bi) The principle of superposition says: When two or more waves cross at a point, the displacement at that point is equal to the sum of the displacements of the individual waves. The individual wave displacements may be positive or negative. If the displacements are vectors, then the sum is calculated by vector addition.

(10c) Refraction depends on the wavelength. As blue light has shorter wavelength moving from air to glass than red so it refract more than red.

No (11ai) Reactance is the opposition of a circuit element to the flow of current due to that element’s inductance or capacitance.

(11aii) Impedance is measure of the opposition to the flow of alternating current through a circuit

(8ai) Work is said to be done whenever a force moves a body through a certain distance in the direction of force and is equal to the product of the force and the distance moved.

(8aii) Workdone = Force * distance = F*S F = m(v/t) Workdone = m(v/t) * 1/2vt = 1/2mv² Ek = 1/2mv² ie workdone = change in kinetic energy of the body

(8bi) Kinetic friction is the force that must be overcome so that a body can move with uniform speed over another body

(8bii) (i)Nature of surfaces in contact (ii)Depends on the normal force pressing the surfaces together

(8ci) Tc – umg = ma Tc – (0.3 * 3* 10)= 3*2 Tc – 9 = 6 Tc = 9+6 = 15N

(8cii) TB – 2umg = ma TB – 2(9)= 3*2 TB = 6+18 TB = 24N

(8ciii) TA – 3umg = ma TA – 3(9) = 3*2 TA – 27 = 6 TA = 6+27 TA = 33N

Please the theory question for 2022

I think it’s real

Thanks 4 everything, but are these the correct things?

Is this the real answer for WAEC GCE physics 6th of December 2021??

It’s look real

Sorry but are they real

I think so 😕😞

WAEC Physics Questions – Free WASSCE past questions for Physics.

Here is collection of Physics past examination questions to assist you with your studies for the West African Senior School Certificate Examination (WASSCE) for both School and GCE candidates.

If you are in your last stage of Secondary School Education (May/June) or not in the School system (GCE), the importance of using old exam papers in preparing for your West African Senior School Certificate Examination (WASSCE), cannot be over emphasised. By using past exam papers as part of your preparation, you can find out what you already know. By the same token you also find out what you do not know well enough or don’t know at all.

See: WAEC Timetable for May/June Candidates and WAEC Timetable for GCE Candidates .

What is more, the WAEC past questions for Physics can also be used as an organisational tool to manage your time better, as you can plan according to each section of the paper.

As a matter of fact, revision is more better than memorising facts and going over notes. You can practise for your  Physics WAEC Exam by answering real questions from past papers. This will give you a better chance of passing.

WAEC Past Questions for Physics

Click on the year you want to start your revision.

• Physics Paper 2 (Objective and Essay) – November 2011

Do you have any other past question(s) other than the ones listed here? If yes, don’t hesitate to share them with others by sending it to  [email protected] .

You have to keep trying more than one exam to increase your success in the forthcoming WAEC Exam.
