Politics / Re: Peter Obi's Supporter Displays Gun, Threatens Whoever Votes Tinubu, Atiku by P0lyMath: 3:33pm On Jul 11, 2022 |
EfonAlaaye2023: To imagine that in 2020, you were in Nairaland begging for 150k because of the hardship in Nigeria. If Tinubu becomes the president of the country, I hope your life would be like the way he managed Lagos. |
Phones / Re: Elon Musk: Commercial, Government Users To Pay For Twitter by P0lyMath: 8:51am On May 04, 2022 |
Segunaja: Utter rubbish actually. Twitter is a social media which thrives on advertisement. Without the users in the first place, they'd not have a market. What about paying the users from the proceeds of their ads 3 Likes |
Foreign Affairs / Re: Russia Takes Issue With Israel's Sovereignty Over Golan Heights& Jerusalem(Pix) by P0lyMath: 10:45am On Feb 26, 2022 |
dawnomike: Not true. Yeah, Israel took the Golan during the 6 days war, but did they start the war? The war came to Israel, they fought and got the Golan. Russia is the one bringing the war to Ukraine. |
Romance / Re: What's The Worst Thing A Woman Has Done On The First Date? by P0lyMath: 2:31pm On Jan 29, 2022 |
InsanePsycho: Seems you guys replying her are the ignorant ones. Women can in fact get pregnant as a result of sex during menstruation, perhaps not during the menstruation period. Especially, if it's the last phase of the menstruation, the sperm could still stay around to fertilize the eggs after the menstruation period. |

Even if you have an old PC you're not using, and would want to dash it out, please I'd be glad to accept it. |
Computers / Can Someone Please Help Me With A Laptop by P0lyMath: 4:37pm On Nov 06, 2021 |
Can someone please help me with a laptop? Mine spoilt last two weeks. The motherboard spoilt and I don't have money to change it. I'm a software developer(Backend with NodeJs, but learning ReactJs seriously to become full stack before the end of the year), looking for job and upgrading my skills as well. Since my PC spoilt, it hasn't been easy applying to jobs and all. If I can get a laptop on loan, to pay back as soon as I get a job(while I hope someone trusts me), I'd really appreciate the kind gesture. |

I'm still afraid of how I'll continue with the story when this last account stands to be banned for no reason. Why would I be banned. Please those that know the mods in this section should intercede on my behalf please. |

horpeyemmi66: Just wanna chip in something ßoss. U missed something in ur formula. g'=g[R/(R+H)]² Simply solve to get 2.45m/s² ===========> as can be seen from the question, height is quite to large as radius of the earth. So when the height is significantly less than the earth's radius, then this formula will be more convenient g'=g[1-2H/R] For no2 Use the formulae g=4πGRp/3. U already know what acceleration due to gravity at earth's radius should be na(9.8~m/s²) meaning that what u got can't be the answer. Who re my to undo the latchet of my ßoss FIGHTING |

A really brilliant attempt to u guys... Bravo! But horpe smashed it, so u guys should go through his workings and if there's any hitch, u can tell him so that he can annotate on it... FIGHTING |

Calculate the vertical distance travelled by a projectile whose initial velocity is 20 m/s at an angle of 30° to the horizontal after travelling a horizontal distance of 10 m FIGHTING |

Horpeyemmi, ur diplomacy still amazes me. I'll keep on fighting till I get a positive result To the guys asking of the putme form, u guys should relax cos our guess is just like u guys' own. Like mathefero has annotated on the issue, u guys should all stick around this thread for the current trend on UI matter. Like seriously, it irritates me to see comments about the putme form!

To my questions, u guys got two out of the three. No2. Let them meet at 'x' measured from the top of the tower. Let O' be the ball from the top and O'' be the ball from the foot of the tower. Distance travelled by O'=x Distance travelled by O"=50-x X=gt²/2=4.9t².........…………1 50-x=ut-gt²/2 50-x=25t-4.9t² X=50-25t+4.9t²…………………2 Equating 1 and 2 50-25t+4.9t²=4.9t² 25t=50 t=2s But x=4.9t² X=4.9(2²) X=19.6m Therefore, their time of crossing each other is after 2 seconds and they crossed each other at 19.6m measured from the tower top.

@Horpeyemmi66, u tried for the other questions though u re more than it. But that No2 is a big NO. @Thaotech, u tried wella bro but u need to be conscious of what a question wants(0.32N=320g) That no2, really puzzled me before I could solve it. FIGHTING |

1. A body of mass 10kg in equilibrium by two ropes. If one rope pull the body horizontally and the other at 40° with the vertical, calculate the tension in each ropes. 2. A stone is dropped from the top of 50m high tower. At the same time another stone is thrown upward from the foot of the tower with a velocity of 25m/s. At what distance from the top and after how much time the stones cross each other. 3. The uniform metre rule balances on a knife edge at the 55cm mark when a mass of 40g is hung from the 95cm mark. Find the weight of the ruler FIGHTING |

Pr0ton: Though it came a lil bit late,...... Mass/min=1000kg/min Works one in lifting water through pump=pAv(gh) But pAv=m/t Workdone=m/t(gh) Work /min=1000(10*40) Work/min=400000J/min 2. Work done in the nozzle is the kinetic energy given to the water thus pumped. Work=m/t(1/2V²) Work/min=1000(1/2*6²) Work/min=18000J/min 3. Power in watts means to convert the mass/min to mass/second=50/3 Power=m/t(1/2V²+gh) Power=50/3(18+400) Power=6966.67watts Power=6.97kw FIGHTING |
