I got a little mixed up with the linear dependence/independence, but I understand now. Thanx
I have another question though.. just want to make sure if my answer is correct:
Let S= Span {(1,1-3), (2,2,-6) , (-4,-4,12)}.
Is the basis of vectors = {(1,1,-3)(2,2,-6), (-4,-4,12)} ?
Question about "Span"
Given 3 vectors:
v1=(1,1,2)
v2=(1,0,1)
v3=(2,1,3)
To determine if they span R^3, I placed these 3 vectors in an augmented matrix. I found the determinant to be 0 which means that the 3 vectors do NOT span R^3. My question is, since v1,v2,v3 are linearly dependent...
Oh ok. It's at 90 degrees from B then. That makes more sense. Basically, the side that is 30 degrees from B is the bottom wire right?
Thanks for your help
Hello.
I have a question about RHR #2 (Force in a conductor).
If IL X B = F and
If the fingers represent the direction of the current, the thumb represents the direction of the force and the palm is the direction of the magnetic field, how come the magnetic field can be at an angle...
Well, it's a little bigger, but still kind of small

Basically, I know that
I = 5 A
B= 0.5 T
the sides of the loop are 0.05 m long
The loopp was rotated around the Y axis and makes a 60 degree angle with the X-Y plane
I...
I know that the formula to calculate the TE is
(#of transformants)/(g of DNA) * (Final volume at recovery) / (Volume plated)
but what exactly is "fianl volume at recovery"? Do I calculate the total # of pGal DNA, X-gal and recovery broth that I mixed up?
Hello. I am working on this problem
0=0.002*e^-(0.005/2R)
I am supposed to find to find "R". The only way I know how to do this gives me 0... but I know that it's not the answer. Got any tips?
