Odilop: Define heat of atomisation

great.david:
you're correct sir....image is at infinity ..i think you've said it befor my post.....mind you image come only be found in such position in a concave mirror,so you don't need to ask if concave or convex....PEACE

prince CEE: solve the equation......
8x = 4^x

bee2me: x=0

prince CEE: solve the equation......
8x = 4^x

ChocolateBarbie: X = 0

Urom Ota:
x=2

Urom Ota:
how is x=0 pls. I dnt agree with u. If x=0, den 8*0=0, while 4^0=1. The correct answer is 2. X=2. Tnx

Ai-bi-ke:
A light ray reflected normally from a plane mirror to a meter rule through a distance of 5cm,what wil be d value of f d displacement of d reflected ray if d mirror is rotated thru an angle of 15degrees?

ChocolateBarbie: show yo calculations plz

Odilop: Line of equal dip qnd declinqtion qre cqlled?

prince CEE: this is the answer!!!
Cos15 = x/5
x = 5cos15
x = 5 * 0.9659
x = 4.83cm

take dis smple 1,.. If the tire of a bicycle has a diameter of 14m,what wil b d value of the total distance covered in meter if it rotates 50 times( TT=22/7)
a.4400m b.2200m c.88m d.1100m
ur workings wil b highly appreciated plz!

mgb4reel:
B.
D shape of d tire of a bicycle is with no doubt dat of a circle. Therefore, its perimeter say p is 2*pi*r where r = 7m. p = 44m. Rotating 50 times implies total distance d = 50 * 44 = 2200m.

prince CEE: meridian?
Cos i ve really forgotten most of magnetic and electromagnetic stuff

bee2me: Whats the function of FUSE in an electric home appliances...wat does the combination of oxygen and ethyl produce nd its function...

Ai-bi-ke:
u almost got it sire,but nt perfctly

remember dhat wen a mirror is rotated,d new angle of reflected ray s twice d angle of rotation!
Apart from dis,u are to use tan of d angle and nt cos!
