Heartbrokengirl:
After the party that day, it was late to go back to my house and his house was farther, so we decided to book a hotel around. That night was our most intimate night. We kissed, he gave me leg massages, a head and said he is ready when I am ready. I was blown away. Could this be real?
@bolded. You shouldn't have allowed this to happen, especially the head he gave you.

When you're not 100% sure marriage would happen between you and a man, don't allow this!

The memory of it might keep hurting you. Your future husband might want to know about this. What will you tell him?
PropertiesRe: Our Tenant Refuses To Vacate Our Apartment After About 10 Months Quit Notice! by WAECMATHEMATICS(op):
https://www.nairaland.com/5590755/tenant-refuses-vacate-apartment-after

Our tenant Mr Chigozie Okongwu James has refused to vacate our apartment for close to two years now!

He was given a quit notice since February 2019 at the Lagos Mediation Centre. His house rent had expired before he was given the quit notice.

Up till now, he has refused to leave the house! This December 2020!

Lagos State needs to do something about stubborn tenants like this man. This is one of the things causing crises in the society. When cases like this degenerate into violence, Lagos State would want to absolve itself from the crisis.

Lagos State needs to be more proactive to avoid breakdown of law and order.

HealthRe: Bad Breath Wants to kill me! Help! by WAECMATHEMATICS: 9:07pm On Nov 11, 2020
Fizzy drinks are one of the major sources of bad breath in the world today unknowingly to many people.

Avoid fizzy drinks before interacting with people.

If you have to drink fizzy drinks before interacting with people, then, brush your mouth thoroughly after drinking. That'll only mitigate the effect because the carbonic acid you have consumed stay in your system for some time. You might need to brush your mouth repeatedly to have fresh breath after drinking fizzy drinks.

The carbonic acid in the fizzy drinks aid the exponential growth of bacteria in the mouth. That's responsible for bad breath.

CrimeRe: Where Do Bullets Go When Fired Straight Into The Air? by WAECMATHEMATICS: 1:29pm On Oct 25, 2020

Ok

Now, terminal velocity is the point where the force (gravity) acting on the bullet equals the force opposing it (air drag).

We are not the first to start this argument. We also have too many variables to do a simple math so lets adopt what has been done by professionals.

It has been established that the terminal velocity of a bullet is about 90m/s or more. Thats over 200mph

AK-47 muzzle velocity is upwards of 700m/s.

You can see the difference. The question is, is 90m/s lethal enough to penetrate a human skin. This question boils down to shape and size of the bullet. A pointed tip bullet should do more damage than a rounded tip. So the type of bullet is an important factor.

Also, it has been established that a bullet during a free fall does not turn towards its pointed side. It most likely lies with the side that gives it the lowers center of gravity which is usually its side. This creates more air drag and also reduces its penetration power if it hits a human.

One thing is for sure, such bullet will cause a serious bruise, or skin tear but less likely fatal even though it has been established that it has and could be lethal but the chances are slim.
Excellent analysis!

Those falling bullets that cause deaths most likely have speed far more 90 m/s with higher density.

You are wrong.

A bullet shot does not travel indefinitely. Air will resist its movement. Gravity wants it to fall down. A bullet shot at 45 degrees will either meet an object or travel at the same 45 degree until the momentum it has drops to that which gravity will start to pull it down. From the moment gravity starts acting the line of travel bend towards the center of the earth. At that moment, the momentum it has cannot penetrate human skin.

Myth busters did an episode on it. Study physics, you will understand.

A bullet shot at 90degrees will be more dangerous. You will never see a trained gun handler shooting vertically in the air. The bullet will stall when it lost all momentum, gravity will return it to earth at a speed higher than a 45degree bullet. It may still not penetrate but will certainly hurt more.
Check this:

WAECMATHEMATICS:
Interesting and technical topic!

When a bullet is fired almost vertically into the air, the bullet would keep going upwards in the sky, while it speed reduces, until it reaches maximum height. Its speed reduces because of gravity and air drag. At maximum height, the speed of the of bullet would be zero.

For the return path of the bullet's journey (i.e. falling down), it's initial speed is zero. It's like a mango hanging on a tree about to fall.

As the bullet falls, it's speed increases (i.e. it's accelerating). This falling speed would not keeping increasing forever. This speed would keep increasing until it attains Terminal Speed. Terminal speed simply means maximum constant speed the bullet would attain while falling.

After the falling bullet attains terminal speed, it would continue to fall with that same constant speed with no acceleration.

Falling objects attain terminal speed because of the presence of air i.e air drag. So, the falling terminal speed is considerably small when compared with the muzzle speed (i.e the speed with which the bullet was fired at the beginning.).

Assuming there is no air drag, the bullet would return to the ground with the same speed with which it was fired! Deadly!

So, the bullet returns to the ground with terminal speed, a relatively small speed when compared with the bullet's starting speed.

The bone of contention: How dangerous is terminal speeds of bullets?

Bullets are highly streamlined to defy air drag as much as possible. They are highly dense so as to cause as much damage as possible. With this two factors, the terminal speeds of bullets are considerably high when compared with other objects.

Even though when a falling bullet is not accelerating, it could still be lethal depending on the weight and the height it's falling through.

Kuwaitis were having end of war celebration one particular year and their soldiers were firing bullets into the air. Falling bullets killed about 20 of the civilians who came to celebrate with them! Even though the falling bullets were falling with terminal speeds, the bullets still killed some people at that ceremony.

Summarily, falling bullets can kill depending on the type of bullets and the angle of projection. So, take cover when armed men start shooting even into the air!

ArewaOduduwaBia:
As a scientist, I bet to disagree with the OP where he said 'a bullet would return to the ground with same speed with which it was fired, if there were no air drag'... rather a bullet will travel farther upwards and returns to the ground with a constant speed through out till it touches the ground.
@bolded is a statement of fact.

FamilyRe: Woman Gives Birth To A Baby 5 Months After Giving Birth To Twins In Lagos (Photo by WAECMATHEMATICS: 10:39am On Oct 06, 2020
DBestDoc:
People probably do not know the kind of powerful hormones released by the woman’s body during labor.

Oxytocin and prostaglandins released during labor make the womb contract such that all contents of the uterus (baby, amniotic membranes, placenta) are expelled.

How then did this 3rd baby survive this powerful force of uterine contraction, remain retained and born alive after 5 whole months?
Let a term pregnancy be carried on for 3 extra weeks and see if the baby will be born alive or a small placenta tissue retained in the mother and see if she won’t come up with life threatening bleeding and/or infection.

The believers of this story are just embarrassing God.
Nice contribution Doc! Well done!

I want to ask a question please. On Superfetation.

Assuming a woman conceives of a second baby after 5 months of pregnancy (which is most unlikely), when the first child is ready for delivery, the second foetus would still be around 4 months in the womb.

How can doctors salvage the situation so that the first child is delivered successfully while the second child would also be delivered successfully at a later date?
FamilyRe: Woman Gives Birth To A Baby 5 Months After Giving Birth To Twins In Lagos (Photo by WAECMATHEMATICS:
Ibime:
Superfetation after 5 months? Nah,...
If the conception of the second baby takes place after 5 months of pregnancy (which is most unlikely), then, it's possible for a woman to give birth again five months after the first delivery, assuming the foetuses have different placentas.

But then, one would expect doctors to have discovered the presence of the second foetus while preparing for the delivery of the first baby.

This why I have problem with the bolded in the statement below.

Good day.
Sorry for belated response. I just saw your message now. Don't mind the guy that was discouraging you in that your thread. You can actually package some of your research as books and sell on Amazon. However, you'll just need to reference the sources in your books. You'll need to give credit to the original owner of any information or picture you use in your books. Just give it a trial.

On how to upload your books on Amazon, there are basically two ways you can achieve this:

1. If you have somebody in US, Canada, UK or any of the countries approved by Amazon, just contact the person. Prepare the soft copy of the book and send to the person. The person will then help you to upload it on Amazon.

2. You can consult some publishing companies here in Nigeria. They'll charge you certain amount of money and they'll do it for you.

Check this link for more information on that:

You can contact okadabooks.com.

Note: You cannot upload books from Nigeria because Nigeria is not one of the countries approved by Amazon.
