- Select all correct answers (i.e. more than one answer may be correct). Which of the following statements about EMG recorded from a single person are true? For a sustained, submaximal isometric muscle force, the EMG activity will increase with fatigue. For isometric muscle force generation under different force magnitudes, muscle EMG will be smaller for small forces (e.g. 50% max effort), and muscle EMG will be larger for large forces (e.g. 100% max effort). Assume no fatigue.The current I is equal to?Part (a) Find the direction of the force for wire A in degrees.

Why is it important not to apply more than 10N of force while doing the experiment? Newton's 3rd Law breaks down for forces greater than 10 N. You could easily strain yourself by exerting 10 N of force Forces greater than 10 N cause the sensors to put out so much electrical current that there is a danger of electrocution Above 10 N, the sensor output flatlines and meaningful data cannot be obtained. both a and d
