hmmm but the actual diagram is not like this. mind explain?

why ??


ps: what doest | p + q | means.. distance rite?

oh! we nid to get the resultant vector rite?

thx pro

whats the ans

triangle - sector of circle
= 32 - 25.136
= 6.864

same with you. issit using the line method?

angle X pi/180

---

Added on November 27, 2010, 1:03 pmi have the same ans with yours too

mayb the ans given is wrong?

ar^(n-1) > 11

45056 x 0.25^(n-1) > 11

(n-1) log 0.25 > log (1/4096)

n-1 < 6

n < 7

n = 6

log 0.25 = negative ans

so u must change the direction

(1/4)^n-1 > 4^-6

4^(-n+1) > 4^-6

-n + 1 > -6

-n > -7

n < 7

n = 6

high resistivity = easier produce heat as P = I^2R, increasing of resistivity increase resistance as well as the heat

angle x pi/180 = rad.

rad x 180/pi = angle.

it jus the same. 45 x pi/180 *put the pi there

sry. i get it d

10 = A x 5
A = 2

V = 2 x 3
= 6

P = 6 x 2
= 12

ans B

C

npn but connect emitter to + terminal? impossible

for question 10

10N = 4cm
1N = 0.4cm
30N = 12cm

in parallel series = 12/2
= 6cm


for question 37

gradient = (1.2 - 0.4)/(0.84 - 2)
= 1.25 C

given R=[perfect squares that are less than 8]. Find the possible number subsets of R.

A 1
B 2
C 3
D 4
D

Any rational number that is the square of another rational number. In other words, the square root of a perfect square is a whole number. For example, 0, 1, 4, 9, 16, 25, etc. are all perfect squares.
