Assume that the turntable deccelerated during time δt before reaching the final angular velocity ( δt is the time interval between the moment when the top disk is dropped and the time that the disks begin to spin at the same angular velocity). what was the average torque, ⟨τ⟩, acting on the bottom disk due to friction with the record?

hello, i am papaguy.
i have found an answer to your question but use it as information.
information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.
best of luck!
as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
not copied too! hope this !
