(1) 6.7*10^3 times when g=10m/s2, but if g=9.8m/s2, 6.8*10^3 times (2) 800J (3) 20J (4) 1st speed=240km/h, 2nd speed=480km/h

...e-mail me ..we will talk about it...av u heard abt team tutors in ui...preparing ppl for post utme..

Damayogenius18:
....OK...send it....

Damayogenius18:
....bro, how r u...long time..

Pes13:
Done.

Adethemeji:
We've created a study group on WhatsApp
where we study questions on different subjects
add me up on WhatsApp if you're interested

Pes13:
Have added you.

For everyone who has been added, pls, strike out your number.

...send ur number to me trough mail..I will send it to u via WhatsApp...no need

Hybridization is the mixing of two or more orbitals of the same principal quantum number to give a new set of orbitals that are exactly equivalent. TYPES OF HYBRIDIZATION (1) sp three eg alkane (2) sp two eg alkene (3) sp eg alkyne.

Damayogenius18:
..it is the mixing or blending of orbital to av orbital of the same energy or to av the same degeneracy...p orbital has slightly higher energy than s orbital..but when hybridize,they will both have the same energy...a new orbital is form different from the original s
and p orbital..the new name of the orbital is now called sp orbital...we have sp,sp^2( called sp two not sp square) also sp^3....

Damayogenius18:
..lol..I miss u guys too.. But from Monday..I will always come online at 2am....

Eben331:
is dat important?

Eben331:
but image distance is supposed to be in cm or m, you mistake ve for velocity. The ans is not correct ooo

Eben331:
I first used h=l(1-costita) and later use v=_/2gh I dnt knw weda it is correct. Can u show how u got 30m/s?

Damayogenius18:
...OK bro...only back to solve ur ques

Eben331:
Hint: First find vo(image of objective lens) nd ur new u will be vo, then find ve which is the final image.

Eben331:
You are correct

For the first 200km, the time spent is
200÷44=4.54hrs

For the next 220km, the average speed is 220/9-4.54hrs
This is because the total time spent is 9hrs
220/4.45 =49.43km/hr. Am I right?

1 A ball of mass 1kg is dropped from a height of 5m onto a floor and rebounds to a height of 1m. Find the loss of kinetic energy due to impact. (g=9.8m/s2) 2 An electron of mass 9.4*10^-31kg has a wavelength of 1.3*10^-10m. Calculate the velocity of the electron. (h=6.6*10^-34Js) 3 A compound microscope, with lenses of focal lengths of 3cm and 5cm for the objective and eyepiece respectively, has an object placed 2cm from the objective lens. If the first image formed 3cm from the eyepiece lens, calculate the distance of the final image from the eyepiece. Happy Weekend Bosses.

A man drives a car a distance of 200km at an average speed of 44km/h. What must be his average speed for the next 220km if he is to cover the total distance in 9 hours?

Na Google u use

Weldone!

I don't think there is an answer in the options
As I got 1.47×10-² as a final answer

Guys, hello! I wrote Phy, Chem, Bio and Eng in UTME. Which subject combination wil I write in POSTUME and what materials in terms of textbooks/past questions shud I use 2 prepare 4 it. I applied 4 MBBS

Damayogenius18:
...use both lamlad and science physics...don't say you can't get it or its not in ur side..do everything possible to get it...u can just use ur essential as reference...if you can get new school, u shld too...BT try and get science physics and lamlad physics..there is a phy book I still want u to get BT will send DAT to u 2ru mail...

If Pico = 10-¹² then Femto =? (a) 10-¹³ (b) 10-¹¹ (c) 10-¹5 (d) 10-¹4

Damayogenius18:
...cant u see?can decipher simple post...guess I need to leave nairaland now....one of those day..

samuelizz:
You can use lamlad, it is a very good text.

Damayogenius18:
...your teacher tot u wuru wuru method to get right option....pls can u recommend that teacher to me.....lol...
