If you use the form q = kA(T2-T1) and perform dimensional analysis on it, you would arrive at the units of k = W/(m^2*K). But do these units hold true in the differential form? dT/dt = -k(T2-T1)?

I worked out that 20mA = 20000A and 30 minutes = 1800s and I=Q/t

So that means Q=It = 20000 x 1800 = 360000000 C

My friends say i am wrong, can you please help me?

the original problem deals w/ finding the derivative of
F(x)= 4X^(1/6) -3x^(-1/6) +3

ok, no problems so far...i go in, apply the power rule, and get

4/6 X^(-5/6) + 3/6 X^(-7/6)

the thing is, im having trouble combining them, in my answers i get numerators in the top, like 3+4 (all numbers), however all the "correct" answer choices have "X" in the top AND in the bottom.

any help?

-confused-

Solve this inequality. Express the solution in set-builder notation: 7(x - 2) + 16 < 3(2 + 3x). Graph your solution on the number line. Be sure to do your solution check.

Why do they use the same term for loudness of music and for space contained somehow? Is it because when I increase the volume of my speakers there's a bigger volume in which the sound can be heard or is it something else? more exotic, perhaps?

(a) Express the vector ~A= (Ax,Ay) = (−5 m,−2 m) using unit vectors ˆı and ˆ|.
Also express ~A in magnitude and direction form (|~A |, ), where the angle is measured
with respect to the positive x-axis, anticlockwise angles being positive.
(b) An acceleration vector of magnitude 9.81 m/s2 makes an angle of 75 with the positive
z-axis. Find the scalar components of the vector parallel to and perpendicular to the zaxis.
You now rotate the z-axis until the scalar acceleration component parallel to the
z-axis changes sign, becoming equal to the negative of its previous value. What now is the
angle between the vector and the z-axis?
(c) When vector ~C is subtracted from vector ~D , the resulting vector is equal to twice the
sum of the two vectors. Write this condition as a statement in vector algebra involving
~Cand ~D
. Show that this requires that ~D is a scalar multiple of ~C. Find the ratio of
the magnitudes of the two vectors, and the angle between them. Draw a diagram to show
their relationship.

At two points (1 and 2) in the motion of a particle, the instantaneous velocity
vectors have equal magnitudes of 20 m/s. At point 1, the velocity vector ~v1 points in the
positive x-direction. At point 2, the velocity vector ~v2 is at angle −45 to the positive
x-direction.
(a) Resolve ~v1 and ~v2 into rectangular scalar components. Do not forget the physical units.
(b) Take the difference of the two velocity vectors, ~v = ~v2 − ~v. Express this difference
in rectangular components.
(c) Divide the difference you found in part (b) by the time t = 6 s it took the particle
to travel between the two points. This gives ~v/t, the average acceleration ~aavg of the
particle over the interval between point 1 and 2 on the trajectory. Give the magnitude and
direction (angle with respect to the x-axis) of this average acceleration.

For example, I have recorded a macro in an excel file and i need some data from a different saved file (i.e. txt or .xls). How do i use macros so that i could open that file and input the needed data from that file into the worksheet where i have recorded the macros?
And also, how would macros detect an error if the file chosen by the user is not the file intended for that purpose?

why is that all planets revolve the sun , maintaining the same distance to it. why not it move towards the sun, due to gravity. or move away from sun.
