You're one intelligent dude I know around here.
Respect.

thank you so much sir

I found this picture on the internet and wonder what messages it's passing.

Truly it's passing a message but it all depends on how we interpret it.

Let's see your interpretation of Lalasticlala and other mods.

House what do you feel?

WAECMATHEMATICS:


Huygens' Principle is not an O' Level topic in Physics. It comes under A- Level.

In Cambridge curriculum, it comes under AS Level.

Well done for the calculation! Kudos!

alright. Thanks for the correction

I've gone through the articles and they're not really helpful. They are not comprehensive at all especially the one on population inversion (energy pump).

Thanks. This will surely help a lot. I have an exam I am preparing for on laser and other applications of non-ionizing EM radiations (radio waves, microwaves, infrared, etc).

Veezybaba:

Huygens principle?? please can you enlighten me on this?
Is it o'level physics?

yes, it is O'level physics under waves. The principle talks about secondary waves (wavelets).

In physics perspective, Huygens principle will be deployed as the beam diameter can not be well defined. Therefore we use 1/e² beam diameter (i.e the diameter/radius that encompasses 86.5% of the beam)

Veezybaba:
A security halogen beam light forms a circle of radius 12cm on the wall fence 60cm away. Calculate the slant length of the beam and divergent angle from the source of the light.

Slant length is the hypotenuse = √(60²+12²) = 61.19 cm

Tan θ = opp ÷ adj
Tan θ = 12 ÷ 60
θ = 11.31°

Angle of divergence is 2 times θ
= 2 × 11.31°
= 22.62°

I've looked at it again. I don't think there's a mistake in my final answer.

sorry. You're correct

Miracle911:


Thanks man..

I’d love to see how you arrived at 1.8hrs

the first train travels faster. Their speed is in the ratio 95:75

Using that ratio for their respective distances each of them will cover before they meet; the faster train will cover 171 miles (i.e 95/170 × 306miles) and the second train will cover 135 miles (i.e 75/170 × 306miles)

Using the formula, time = distance ÷ speed
1st train, time = 171miles ÷ 95 miles per hour = 1.8 hours
2nd train, time = 135miles ÷ 75 miles per hour = 1.8 hours

Each of the will therefore travel for 1.8hours before the meet

Answer to the second question is 1.8 hours

TammyAnybody:


Aptitude test might not hold anytime soon due to NCDC guidelines on Covid-19.

they've done the test today

SFCommander2:
Collection of individual documents at the DSS HQ in Ondo State officially ended at 6pm yesterday. Though some where given a final grace of submitting theirs today, but that was after much pleading. We're told that the exams will take place by tomorrow.

you're very correct. Guys did exam today in the afternoon at their Ibadan office.


NB: I didn't apply for the job but a friend that went to DSS office today to submit his application told me this. He wasn't allowed to write the exam too as they told him that the exam was already in progress

I just can't thank Him enough. After many years of searching for something better, God has finally answered my prayers in this difficult times!

Bifrost:
Phew! Can't believe I read all 52 pages.

I have plans of applying for UI master's in 2 years time. I need to save money first abeg.


Who can give a reasonable 'guestimate' on the cost of a UI master's? Including accomodation, living expense for the entire period.

that will depend on the course you want to study. All in all 500k to 600k should be enough (provided you're not coming for professional masters).

So far, I've spent more than 500k and we are just about to write second semester exam before Fg closed down schools and of course the ASUU strike (my programme is a professional masters and my school fee is more than 200k)

PLEASE Help me out
An aeroplane flies from a town X on a bearing of N45E to another town Y, a distance of 200km. It then changes course and flies to another town Z on a bearing of S60E. If Z is directly east of X, calculate correct to 3 significant figures.
Thanks.

This guy dey mumu o. You don resign if they like they should treat it. It is none of your business. Continue receiving the money, if you dont know what to do with it, you can help give to charity. Dont you hv famly members that need help? You want to return back the money to them to embezzle

it doesn't work that way. An act like the one you suggested above can bring a great consequence for him in his new job (esp. federal govt job)

That's a good decision

He resembles Obama in the last picture
