- I need help with how to solve this answer, thank you !arrow_forwardIs work function of a metals surface related to surface energy and surface tension? What is the need to the work function component in the math of tension of metal surfaces that cannot be provided by existing equations of surface energy and surface tension? What are the key differences in each parameter and variables that allow for a differentiation of each function? What has a more significant meaning work function, surface tension or surface energy? Are there real differences and meaning? Please clarify and if possible provide examples . Does surface tension dependant on thickness of a metal or type of metal surface all having the same thickness? Clearly temperature has a profound change on surface tension what other variables besides temperature are key to surface tension. What if any is there a connection between crystal structure of the element and surface energy and tension? This is NOT a Assignment Question!!!arrow_forwardThe cylindrical beam of a 12.7-mW laser is 0.920 cm in diameter. What is the rms value of the electric field? V/marrow_forward
- Consider a rubber rod that has been rubbed with fur to give the rod a net negative charge, and a glass rod that has been rubbed with silk to give it a net positive charge. After being charged by contact by the fur and silk...? a. Both rods have less mass b. the rubber rod has more mass and the glass rod has less mass c. both rods have more mass d. the masses of both rods are unchanged e. the rubber rod has less mass and the glass rod has mroe massarrow_forward8) 9)arrow_forward10) 11) 12) 13) 14) 15)arrow_forward
