I made that way too difficult and over thought everything. Just the area * z .0121*.55t2 take derivative and plug in for t I'd like to thank Doc for his help & patience

My text is of no help. All it does is confuse me even more. So I understand that if it's perp. then you don't need to use the cos of the dot product. I have no clue if it's perp. or not, all I get out of it is the box is an x/y cord. and the field is x/z. I used the dot product of those 2...

Sometime physics confounds me, this would be one of those times. Φ would that be A*B as A=the area\Pir2 and B is the field. Then dΦ/dt would be the derivative of the change in field/change in the time...I didn't think the field was changing?

Homework Statement A 11cm by 11cm square loop lies in the xy-plane. The magnetic field in this region of space is B = (.31t(i(hat))+.55t^2(k(hat)))T, t is in s. What is the E induced in the loop at t = 0.5s? at t = 1.0s? 2.Equations...

I agree but according to the pic i think its measuring the cm but I could be wrong and I found the mass. http://session.masteringphysics.com/problemAsset/1070606/8/14.EX25.jpg

Homework Statement The 14-cm-long wrench in the figure swings on its hook with a period of 0.90 s. When the wrench hangs from a spring of spring constant 380 , it stretches the spring 2.8 cm What is the wrench's moment of inertia about the hook? cm of wrench is also 14 cm according to pic...

thank you my friend...that was much easier then I thought it was.

Homework Statement You and your friend Peter are putting new shingles on a roof pitched at 20degrees . You're sitting on the very top of the roof when Peter, who is at the edge of the roof directly below you, 5.4 m away, asks you for the box of nails. Rather than carry the 2.1 kg box of nails...
