Problem 84

Integrated Concepts One long straight wire is to be held directly above another by repulsion between their currents. The lower wire carries 100 A and the wire 7.50 cm above it is 10-gauge (2.588 mm diameter) copper wire. (a) What current must flow in the upper wire, neglecting the Earths field? (b) What is the smallest current if the Earths 3.00105 T field is parallel to the ground and is not neglected? (c) Is the supported wire in a stable or unstable equilibrium if displaced vertically? If displaced horizontally?

Step-by-Step Solution:
Step 1 of 3

 Gluconeogenesis – formation of glucose from non-carbohydrate sources (comes from protein) – because 58% of amino acids can be converted into carbs  Ketone bodies are waste product of fat metabolism  In brain disorders, the brain really likes fat (ketone bodies)  During periods of starvation, there is a down regulation of metabolic rate and the breakdown of protein  Metabolic rate can slow down to 40% to keep you alive during starvation  After we use fat as an energy source, we revert back to breaking down protein from muscles right before death  S o Hypothermia – lower body temp – tells us that boys has lowered metabolic rate o Bradycardia – the second physical sign that an athlete is under-fueled. o Urinary ketones – means they are starving and breaking down fat  If calorie intake is too low, you will see ketones mid day o Often see increase in urine specific gravity-ketones, because you are producing more and are peeing more out.  When people are put on a high fiber diet and are constipated, it becomes a motility issue (peristalsis)  get them more liquids  Postural Orthostatic tachycardic Syndrome – when you stand up fro a laying position, your HR elevated by 30 beats. o Blood pools in lower body and brain is blood deprived  Could be caused from underfueling, dehydration  If under fueling is significant enough, women miss their periods – estrogen goes away  osteoporosis (estrogen helps with bone deposi
