I am looking to improve the thermal insulation on one of my favorite glass mugs.
I am choosing between a silicone glove or a neoprene wrap.
What is the difference between a silicone baking mat and silicone rubber?
Does silicone or neoprene have better thermal insulation?
I ask, "Does a ferrous pan for Induction Cooking need to be Completely Ferrous?"
In other words, could just the bottom of the pan be a ferrous material for good inductive heat induction?
Could I have a ferrous bottom, and ferrous sides that turn to a non-ferrous material after a couple...
Alright, so the corss product of two vectors will give me a vector that is perpendicular to the plane (which is in the direction that I want).
I'm not sure what these vectors would be? How do I know what vectors to cross?
Homework Statement
I have a coordinate system, (x,y,z). There is a uniform-magnetic-field of 2.0 T that exists along
the direction of the y-axis. There is a rectangular plane bounded by the points
(3,0,0),(0,1,0),(0,1,1),(3,0,1).
Calculate how much flux is traveling through the rectangular...
Yes, I am assuming that the AFM cantilever is being modeled as a second order system. With the cantilever tune, the phase curve is set to 90° of the resonant frequency. So would I be close enough in estimating that the natural frequency is 72.7 kHz?
I was able to calculate the value for the damping ratio; but I am having trouble finding the value of the natural frequency. Any ideas on how to solve for the natural frequency?
Homework Statement
I've been asked to estimate ωn and ζ from the magnitude and phase plot of an atomic force microscope. The magnitude and phase plot is attached.
Does anyone know how to solve for these values?
Homework Statement
A 2400/240-V, 60-Hz transformer has the following parameters in the equivalent circuit of Figure 6.5: the high-side leakage impedance is (1.2+j2.0)Ω, the low-side leakage impedance is (0.012+j.02)Ω, and Xm at the high-side is 1800 . Neglect Rhe. Calculate the input voltage...

Homework Statement
In a collision between an electron and a hydrogen atom, it is useful to select both objects as the system because:
A. The total momentum of the system does not change during the collision
B. The forces the objects exert on each other are...
