Answer:
40 toothpicks
Step-by-step explanation:
3 times 4 equals 12, so I would multiply 10 times 4 and get 40.
Longer wavelength means lower frequency (lower pitch)
Ok so...
You want to move the decimal point to the right until the number is greater than 1 but less than 10.
The number will end up being 5.2
You moved the decimal point 3 times to the right.
So it will be 5.2 x 10^-3. It is negative because you moved it to the right. The exponent would be positive if you moved it to the left
