Speed= (frequency) x (wavelength)
= (2 per second) x (5 cm) = <em><u>10 cm/sec .</u></em>
Answer: number of bacteria
Explanation:
A easier way. I like to remember it is that x axis = independent and yaxis = dependent variable, but if that doesn’t help think about this
Why would the number of bacteria effect the amount of time. It doesn’t make sense because time goes on forever and nothing can change about it but time can change the number of bacteria because if you had a timer of 30 seconds and the bacteria is for example 10 and if you had a timer of one minute then the number of bacteria change because of time, if you flip it, it doesn’t make sense
Answer:
Light does not need a medium to travel travel through, but since waves must have a medium to vibrate, sound is not created where no air is present.
Explanation:
Prior to determining the
