Answer:

9.2 V

Explanation:

The RMS value of an AC is the effective value of a varying voltage or current in DC, that is the equivalent value of the AC which produces the same effect as an DC. For example if a motor is supplied by a 9V RMS voltage, it will rotate as if the voltage applied was 9V DC.

The RMS value is given by:

RMS voltage = Peak voltage * 1/√2

Given that the maximum voltage should not exceed 13 V, this means that the peak voltage is 13 V. The maximum RMS voltage is:

RMS voltage = Peak voltage * 1/√2 = 13 * 1/√2 = 9.2 V

Based on the information presented in the graph, what is the velocity of the object?
Sladkaya [172]

Answer:

3 m/s

Explanation:

<u>The velocity of a position-time graph is the slope of the line.</u>  Slope is rise over run, or rise divided by run.  The rise (how many units the line goes up) is 3 units and the run is 1 unit.  3/1 is 3, so the velocity is 3 m/s.
