From Newton’s second law, we have F =W = 200 / 1000 x 400N

Physics Essay and theory sample Questions and Answers for paper 2.

Below are the showing working of the WAEC Physics essay and theory sample questions and answers for 2021 paper 2.

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.

Solution: impulse (I) = Ft

=5×0.03

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.

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 0 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 10 11 m, and the diameter of the sun as 1.4 X 10 9

Let the width of the image = h (m)

tan8 0 = h/0.5m

h = 0.5 X tan8 0 = 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 10 11 =tan0

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

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.

So kindly follow the way each of the questions is solved and master them.

Range : Range(R) is defined as the horizontal distance from the point of projection to the point where the projectile hits the projection plane again

R= U²sin2θ / g

No (7a) Magnetic materials are materials studied and used mainly for their magnetic properties. The magnetic response of a materials is largely determined by the magnetic dipole moment associated with the intrinsic angular momentum, or spin, of its electrons.

(5a) Forbidden gap is the group of energy levels that cannot be occupied by the electrons, these energies lies in between conduction band and valence band.

(5b) (i) free electrons which have negative charges (ii) holes, which have positive charges

(i)by heating past the Curie point

(ii)by applying a strong magnetic field

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).

The lower fixed point, or ice point, is the temperature of pure melting ice at normal atmospheric pressure. While The upper fixed point, is the temperature of pure boiling water at normal atmospheric pressure.

 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

SPM TRIAL PAPERS Physics/

SPM Study Group | Feel free to join our whatsapp study group for latest SPM study resources ❤️ 😊

🔥🔥🔥 MAGIC AI TOOLS 🔥🔥🔥 MAGIC AI TOOLS was down on 10/4/2024 - 20/4/2024 due to lack of funding. Problem is fixed, AI model is upgraded and should work even better now. Try it out, it is FREE 😊

Latest Study Tips | JPA scholar revealed secret study tips to get SPM 10A+ and NO, it's not by attending tuition. Here's how.

1. Who developed SPM Trial Paper website?

Few years ago, we were also form 5 students taking spm..

Just like you, we were also stressed and lost sleep because of it. After all, it is one of the most important exams that can potentially affect our future.

Having gone through SPM ourselves, we know how tough it is to do well in so many subjects at the same time.

Thus, we had developed this website, in hopes of assisting our Form 5 juniors to score well in SPM.

You might ask, why a website specifically for SPM Trial Papers?

Because doing tons of SPM Trial Papers had help us score 9A+ in SPM , and received full JPA scholarships for our further studies .

In the next section, we will further explain how SPM Trial Papers can help you score well in SPM. So please keep reading.

2. Why do SPM Trial Questions?

Spm tips are very accurate, they said..

A lot of people out there are selling "SPM TIPS" at a very high price. They claim that their predictions on SPM questions are "PASTI KENA" and "100% SKOR"

But let me tell you the truth after spending hundreds on SPM TIPS.

Having spent lots of cash myself to buy those "SPM TIPS" , I can tell you the truth about it.

Have you ever wondered how those people predict what will come out in SPM? Do you think they have some "insider information" ?

Leaking question is a criminal offence , so it is highly unlikely they would do that.

Then how on earth did they predict the questions with such accuracy?

They actually analyse SPM Trial Question of all states, as well as past year questions. From there, they try to come out with an educated guess on what is going to come out in exam.

If you had look into the thick book of "SPM TIPS", there will be some sample questions that it said is going to appear in the real exam.

But don't be surprised, those questions are nothing but some SPM Trial Questions. They actually do this for good reason.

SPM Trial Papers are similar to real SPM questions.

SPM Trial Papers are set by experienced teachers from various states of Malaysia.

Some teachers who set SPM Trial Paper Questions are also involved in setting the real SPM questions. This means that the questions in SPM Trial Papers may be similar to those in the actual SPM exam.

Finish all Trial and Past Questions, and you will score.

Lastly, I want to emphasize that I cannot guarantee the accuracy of those SPM Tips . Personally, I am not against it, because it at least gives some idea what to study at the last minute.

However, bear in mind that SPM Trial Questions and Past Year Questions are the bases of their predictions. So, finishing all Trial questions and Past Year Questions will likely prepare you well for the exam.

Good Luck for your SPM exam!!

3. Who should I contact for any enquiries regarding the SPM Trial Paper Website?

What is ChatGPT? Here's everything you need to know about ChatGPT, the chatbot everyone's still talking about

• ChatGPT is getting a futuristic human update. 
• ChatGPT has drawn users at a feverish pace and spurred Big Tech to release other AI chatbots.
• Here's how ChatGPT works — and what's coming next.

OpenAI's blockbuster chatbot ChatGPT is getting a new update. 

On Monday, OpenAI unveiled GPT-4o for ChatGPT, a new version of the bot that can hold conversations with users in a very human tone. The new version of the chatbot will also have vision abilities.

The futuristic reveal quickly prompted jokes about parallels to the movie "Her," with some calling the chatbot's new voice " cringe ."

The move is a big step for the future of AI-powered virtual assistants, which tech companies have been racing to develop.

Since its release in 2022, hundreds of millions of people have experimented with the tool, which is already changing how the internet looks and feels to users.

Users have flocked to ChatGPT to improve their personal lives and boost productivity . Some workers have used the AI chatbot to develop code , write real estate listings , and create lesson plans, while others have made teaching the best ways to use ChatGPT a career all to itself.

ChatGPT offers dozens of plug-ins to those who subscribe to ChatGPT Plus subscription. An Expedia one can help you book a trip, while an OpenTable one will get nab you a dinner reservation. And last month, OpenAI launched Code Interpreter, a version of ChatGPT that can code and analyze data .

While the personal tone of conversations with an AI bot like ChatGPT can evoke the experience of chatting with a human, the technology, which runs on " large language model tools, " doesn't speak with sentience and doesn't "think" the way people do. 

That means that even though ChatGPT can explain quantum physics or write a poem on command, a full AI takeover isn't exactly imminent , according to experts.

"There's a saying that an infinite number of monkeys will eventually give you Shakespeare," said Matthew Sag, a law professor at Emory University who studies copyright implications for training and using large language models like ChatGPT.

"There's a large number of monkeys here, giving you things that are impressive — but there is intrinsically a difference between the way that humans produce language, and the way that large language models do it," he said. 

Chatbots like ChatGPT are powered by large amounts of data and computing techniques to make predictions to string words together in a meaningful way. They not only tap into a vast amount of vocabulary and information, but also understand words in context. This helps them mimic speech patterns while dispatching an encyclopedic knowledge. 

Other tech companies like Google and Meta have developed their own large language model tools, which use programs that take in human prompts and devise sophisticated responses.

Despite the AI's impressive capabilities, some have called out OpenAI's chatbot for spewing misinformation , stealing personal data for training purposes , and even encouraging students to cheat and plagiarize on their assignments. 

Some recent efforts to use chatbots for real-world services have proved troubling. In 2023, the mental health company Koko came under fire after its founder wrote about how the company used GPT-3 in an experiment to reply to users. 

Koko cofounder Rob Morris hastened to clarify on Twitter that users weren't speaking directly to a chatbot, but that AI was used to "help craft" responses. 

Read Insider's coverage on ChatGPT and some of the strange new ways that both people and companies are using chat bots: 

The tech world's reception to ChatGPT:

Microsoft is chill with employees using ChatGPT — just don't share 'sensitive data' with it.

Microsoft's investment into ChatGPT's creator may be the smartest $1 billion ever spent

Insider's experiments: 

I asked ChatGPT to do my work and write an Insider article for me. It quickly generated an alarmingly convincing article filled with misinformation.

I asked ChatGPT and a human matchmaker to redo my Hinge and Bumble profiles. They helped show me what works.

I asked ChatGPT to reply to my Hinge matches. No one responded.

I used ChatGPT to write a resignation letter. A lawyer said it made one crucial error that could have invalidated the whole thing .
