Answer:
For the dry and static friction materials, some of these are Rubber, Aluminum, Gold, Platinum,
Explanation:
High friction materials has higher coefficient of friction (COF).
Answer: The color of candy cane
Explanation:
An independent variable is the Variable that the scientist changed in order to change the dependent variable. The scientist changes the color of the candy cane to test the rate at which they dissolve.
At the frequency of 5 MHz, the period of the oscillations is 1/5meg. That's a period of 1/5 microsecond.
There are 5 full cycles in one full microsecond, and there are 2.5 full cycles in a 0.5 us pulse.
You'll have to decide for yourself how damped a pulse of 2.5 cycles is, because the parameters of the definition are corrupted in the question.
The very first option is correct, as any other answer is either incorrect in terms of optics or does not stop you from seeing the apple.
