When a person is sick, it can be recognized, to some extent, whether or not the person has a fever by touching the person's forehead or neck. How does this method work exactly? The person may also "shiver with cold." What is the reason for this feeling?
I am doing a lab design. i need some useful information about How can the temperature of ruler affect the strength of electricity hold of the paper? First i rubbed the rulers with different temperatures,then i try to use the rulers to attract paper pieces to see difference of quantities of paper pieces in different conditions. But actually i need some research about the background and those relevant scientific explanation.
Thank you so much!

Composite materials are low in density and tolerant to damage. One drawback of this new material is that it is not conductive. This increases the chance that a lightning strike will damage the plane. Engineers have redesigned the composites by adding a material to the original composition that is conductive. Identify one anticipated effect of this new material. Explain why the addition of the new material to the composite fuselage design will result in a tradeoffarrow_forward
- Have you ever experienced having a fever? You usually touch your forehead or neck to check if you have a fever or not. You use your sense of touch to tell whether an object is hot or cold or one is hotter or colder than the other. When bathing a baby, you dip your fingers in the water, and when you prepare baby's milk, you sprinkle a few drops of milk on your wrist to check if the temperature is just right. When you are about to fry some food, you sprinkle some water to see if the frying pan is already hot. When you feel you are warm, you often say you have a high temperature. When an object is cold, you often say it has a low temperature. Temperature is commonly associated with coldness or hotness of a body. How do we quantify this difference in the hotness or coldness of a body?

- Your roommate is having trouble understanding why solids form. He asks, Why would atoms bond into solids rather than just floating freely with respect to each other? To help him understand at least one type of bonding in solids, you decide to embark on an energy explanation. You show him a drawing of a primitive cell of a sodium chloride crystal, NaCl, or simple table salt. The drawing is shown in Figure P24.10, where the orange spheres are Na+ ions and the blue spheres are Cl ions. Each ion has a charge of magnitude equal to the elementary charge e. The ions lie on the comers of a cube of side d. You explain to your roommate that the electrical potential energy is defined as zero when all eight charges are infinitely far apart from each other. Then you bring them together to form the crystal structure shown. (a) Evaluate the electric potential energy of the crystal as shown and (b) show that it is energetically favorable for such crystals to form.
