Ahot metal bar is submerged in a large reservoir of water whose temperature is 75∘f. the temperature of the bar 20s after submersion is 120∘f. after 1min submerged, the temperature has cooled to 100∘f. (a) determine the cooling constant k. k= s−1 (b) what is the differential equation satisfied by the temperature f(t) of the bar? f′(t)= use f for f(t). (c) what is the formula for f(t)? f(t)= (d) determine the temperature of the bar at the moment it is submerged. initial temperature = ∘f

less than one you can't create energy

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests

the given statement is true.

sensory memory lasts for a fraction of seconds before the information is lost. it is the shortest -term memory and can be called as an element of memory. example: when we look at something and remember what it looks like, is just a second of observation. it degrades very quickly. it can also be considered as the process of perception rather than considering it as a memory.
