please showe work and steps
You are making instant pudding. You add powder to milk and attack the mixture with a hand-cranked eggbeater. At first, the powder dissolves, the pudding mixture has the consistency of milk, and the eggbeater is easy to crank. Within a couple of minutes, however, it becomes noticeably more difficult to crank the beater. Explain the increased force needed to operate the eggbeater in terms of friction. Discuss whether the following statements are true: "Static friction never does work and never generates heat. Kinetic friction always does work and always generates heat."Explanation / Answer
7.
At first the powder does not have a particular surface...the particles were fine and canbe separated easily as there is no surface binding them together. so initially it was easy to crank the beater.
aftwer a while when the solution is formed a surface of the particles is formed as they are bound together by viscosity. this fluid exerts frictional force on beater which makes it tougher to crank,
8. True
static friction is present only when the body is at rest.so we can say that static friction never does work.
kinetic friction is present only when body is in motion. so there is always a finite amount of work doneby kinetic friction
