Q: During the 'Muscular' lab, students use EMG to study muscle activity. Which equation best represents the calculation of muscle force from EMG amplitude?

$$F = k \times EMG_{amplitude}$$

Q: In the 'Reflexes & Special Senses' lab, the reaction time is measured. If a student reacts to a stimulus in 0.25 seconds, what is the speed of nerve impulse if the distance traveled is 1.5 meters?

$$Speed = \frac{1.5}{0.25} = 6 \text{ m/s}$$

Q: During the 'Nervous System & Spinal Cord' lab, students study nerve conduction. If the conduction velocity is calculated using $$v = \frac{d}{t}$$, what is the velocity if $$d = 0.8 m $$and $$t = 0.004 s$$?

$$v = \frac{0.8}{0.004} = 200 \text{ m/s}$$
