The time base on the oscilloscope is set for 2 ms/cm and the vertical input has a frequency of 3000 hz. how many wave cycles will appear within the 10 cm width of the screen?

60 wave cycles

Explanation:

As the horizontal axis in a oscilloscope represents time, the time base is simply the scale, in other words, the amount of time that each division of oscilloscope represents. Therefore, multiplying the width of the screen times the time base will give us the total amount of time graphed on the screen.

The frequency is the amount of oscillations or waves cycles per second. So, in order to find the total amount of oscillations:

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

overcharge is the right answer system
