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. Figure P24.10

* A 72112:08 stc “.ull a a Archimedes supposedly was asked to determine whether a crown made for the king consisted of pure gold. According to legend, he solved this problem by weighing the crown first in the air and then in water as shown in Figure. Suppose the scale read 6.57 N when the crown was in the air and 5.92 N when it was in the water. What is the density of the crown (in g/em) ? (gold density is 19.3 g/cm) (Answer in 2 decimal places)

Conductor Physics Question

Hi guys this is my last question to ask.

How does it work? Gallium when heated to a temperature of just 85 degrees becomes liquid and with a mild current applied to it has carbon removing property. Without our unique design we form artificial lungs through a proprietary honey comb design and forced air that is heated through coils. The gallium is then recycled as it makes its way through the structures acting as a conductor while absorbing the carbon from the forced air which comes in through rows of high RPM fans. The gallium contains the carbon moving with the force of simple gravity to a carbon separator where it is extracted through plasma and excreted as a solid pellet form where it can be repurposed at a later time. The Gallium is the recycled in a closed loop system and after the carbon is extracted it repeats this process continually. Gallium is eco friendly unlike its other metal cousins. It’s job is to gather and extract carbon in a continuous loop much like a blood stream. Because of the low temp melting point of…

QUESTION 16 Which of the following statements is not true according to kinetic theory? a. Electrical attractions and repulsions between the molecules must be accounted for in the total energy of the ideal gas. b. The energy of an ideal gas only depends on the kinetic energy of the gas. C.

1) Consider the figure below. An electron is fired towards a conducting plate from a distance L. The plate has a surface charge density a and a radius that is much greater than the distance L.. When the electron strikes the plate, it is measured that AK. E. 10 eV, where AK. E.
