???????????????????????????????????????????w h a t=what ?????????????

help me please Melody !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

answer 4 or use a calcuator

My dad was 83 when he died, and at no time did he use a stick.

Is this a case of an exception disproving a rule ?

Might be best to express the function as follows first:

$$f(x)=(e^x+2)^2+1$$

.

1+1=2

Yet another variation on the cheese and biscuits question.

There are 6 choices for the first pen and then 5 choices for the second, so 6*5 = 30 combinations in all.

Torque is force multiplied by perpendicular distance from the force to the object it is acting on.  

Here the horizontal component of the force will simply try to move the object in a straight line (left or right depending on which way it is pointing).  Only the vertical force will tend to rotate the object.

.

Sorry Melody, can't say that I like picking up on mistakes, but

$$e^{x}.e^{2}=e^{x+2}$$,    not   $$e^{2x}.$$

19

the answer is 19

but why the horizontal component of the force will not give rise to a torque ! 

I mean waht is the relation ship between force and torque ?

If you have found the force in part (a), resolve it into horizontal and vertical components.  The horizontal component will not give rise to a torque, but the vertical component will.

The magnitude of the torque will be given by the magnitude of the vertical component multiplied by the horizontal distance from the isolated charge to the centre of the dipole.  

The direction will depend on the direction in which the vertical component of the force is pointing.  If it is pointing up then there will be an anti-clockwise moment, which means the direction of the torque is pointing out of the Page towards the viewer.  If it is pointing down there will be a clockwise moment so the direction of the torque will be into the page away from the viewer.

9 plus 2 equals 11

OMG are you serious i need solve this problem!!

10x2=20

When your timesing anything to 10 just add a number at the end.

10x2= 2+2+2+2+2+2+2+2+2+2=20

get a bag of pixie dust and drop it on the problem 

actually sine is the length of the opposite side  over the length of the hypotenuse  (in any right angle triangle)

sin is short for sine.  It is part of a big subject area called trigonometry.  :)
