WAEC Physics Theory Questions and Answers Sample Questions

Study the steps and master them in case you see similar questions during the exam.

1. A stationary ball is hit by an average force of 50N for a time range of 0.03sec. Calculate the impulse experienced by the ball.

READ MORE  NECO Biology Answers (OBJ & Essay) [5th August 2021]

Solution: impulse (I) = Ft

=5×0.03

=1.5N-sec.

2. Calculate the recoil velocity of a riffle of mass 15kg which fires a bullet of mass 60g with a velocity of 200ms-1.

Mass of the riffle = 15kg, while the mass of the bullet = 60g

The velocity of the bullet = 200ms-1.

Solution.

The momentum before firing is zero

Momentum after firing = 15 x V + 60/100 X 200 = 15v + 12

Since the momentum is conserved, we will have;

15v + 12 =0

v = –12/15 = -0.8ms-1

Question 3. i. What is the width of the image of an object which subtends an angle of 8 at the pinhole of a camera 0.5m long?

ii. How long is the image of the sun on this camera? Take the mean distance of the sun as 1.5 X 1011m, and the diameter of the sun as 1.4 X 109

Solutions

Let the width of the image = h (m)

tan8 = h/0.5m

h = 0.5 X tan8 = 0.5 X 0.1405m = 7cm Ans.

Let the radius of the sun be l (m)

l/0.5 = 0.7 X 109/1.5 X 1011 =tan0

l = 0.5 X 0.7 X 109/1.5 X 1011 = 0.233X10-2m

=0.23cm

Therefore, the diameter of the image = 0.46cm

The combination of the above WAEC Physics questions 2021 and the WAEC Physics answers 2021 samples for essay, theory, and OBJ (objectives) above, will surely help candidates a lot.

How to Pass WAEC Physics Exams 2022 | WAEC Literature In English Expo 2022

1.     Put Reading First.

People who claim that they must stop reading because they have completed their education are completely wrong. It’s a completely erroneous belief or perception to think that once you have completed your education it’s all over. Learning never stops you know; anyone who stops reading or learning will be living with old information and will move around with it. We live in a world that is constantly changing, and in order to be a very successful human being in today’s society, you must keep up with the latest information.

In reality, relying on a single author for ideas or information is not a proper way of getting updated information. To amass enough information, read as many books as possible.

We implore all applicants who are about to take the WAEC Physics exams 2022 to continue reading books relating to their field of interest on a regular basis.

2.     Obtain the Appropriate Preparatory Materials

Exam preparation should not be limited to reading books. The question you should ask yourself is, “What kind of book am I reading, and how will it help me pass the WAEC physics exams?” Here is what you should consider as appropriate prepared material: textbooks, dictionaries, waec Past Questions and Answers and so on.

3.     Attend Extra-Classes.

Attending extra moral classes can be a source of pride for some people. Some people believe they are too big and are unconcerned about it. This is a completely incorrect viewpoint, and you must change it. Extra classes will help you grow, extend, and broaden your intellectual capacity, making it easier for you to understand things.

Extra moral classes, organized by educational tutors, can be observed all over. This type of class can be held after school in the evenings, during the holidays, or after the school day has ended for the term or session.

You will never be sorry if you attend one.

4.     Set Out Time for Rest

Many people who are studying for impending examinations are unaware of the importance of rest and sleep. It’s a once-in-a-lifetime opportunity. When you take time to rest or sleep, your brain relaxes and your mind calms. Everything is new and your strength has been renewed by the time you wake up. If you force yourself to read when you are sleepy or exhausted, you will not be able to perform better; you will fall asleep quickly, and by the time you wake up, everything you read will have vanished.

This is something that all UTME candidates should be aware of because it is really significant.

5.     Maintain a Healthy Way of Life

One of the things that will motivate you as a person is to eat properly and live a healthy lifestyle. You can easily get sick if you don’t eat well and healthily, such as consuming meals that aren’t truly clean, low-quality foods, and you don’t build up your cells to be immune to sickness.

During the process of studying for tests, many students or candidates become weary, dizzy, and even sick. To avoid this, as soon as you notice a symptom of disease, make an appointment with a doctor, your parents, or the people you live with for additional medical attention.

6.     Chatting on social media should be limited.

It is not a proper thing to spend 80% of your time on social media sites such as Facebook, Twitter, Instagram, and others, and just 20% of your time on your academics. You’ll never be able to create it that way. At the very least, make it 80/20. 80 percent of your time should be spent studying and researching in preparation for your upcoming waec exams.

You may always go back to those things after you have finished your waec exams. FOCUS is the key word here.

This is the extent of our discussion at this time. We will provide more information as soon as we lay our hands on it. If you found this post useful, please share it with others.
