other and result in a stronger muscle contraction than a stand-alone twitch. This phenomenon is known as You correctly answered: c. wave summation. 3. Wave summation is achieved by Your answer : d. allowing the muscle to completely relax between stimuli. Correct answer: a. increasing the stimulus frequency (the rate of stimulus delivery to the muscle). 4. Wave summation increases the force produced in the muscle. Another way to increase the force produced by a muscle is to Your answer : a

radio stations broadcast. A radio wave (radiating electric field) propagates out from the source‚ traveling at the speed of light. The source‚ for example an antenna‚ creates oscillating electric(E)/ magnetic(B) fields. These fields are perpendicular not only to each other but to the direction of the traveling wave‚ and travel away from the antenna. The electromagnetic wave is‚ therefore‚ a transverse wave. The electric/ magnetic fields store the energy of the wave. Basically‚ the oscillating current

Measuring the Speed of Sound and Air using a Pulse-Echo Technique Purpose To determine the speed of sound in air using the pulse-echo experiment procedure‚ and comparing it to the predicted speed of sound in air using the measured air temperature of the classroom. Hypothesis I believe that the speed of sound it the air will be close to that of the predicted value. According to our predicted value‚ we should expect the speed of sound in the air to be at a speed of approximately 346 m/s. Materials

British Sound Analysis: A voiceover in the film British Sounds states‚ "Sometimes the class struggle is also the struggle of one image against another image‚ of one sound against another sound. In a film‚ this struggle is between images and sounds." We as spectators are able to make connection with that statement as we watch the segments in the film unfold. As the tracking shot captures the auto assembly line‚ the diegetic sounds of the noisy machines overwhelm us. This similar technique can be

Mechanical Waves Background Mechanical waves are waves which require a medium for propagation since energy is transferred via the motion of the medium. An example of a mechanical wave is sound. Transverse waves are waves which vibrate perpendicular to their direction of propagation. Surface water waves can be classified as a transverse wave. All electromagnetic waves are also examples of transverse waves. A longitudinal wave is a wave in which its particles vibrate parallel to their direction of

Title: The Sound of Silence Which version of “the Sound of Silence” did you like the best-the poem‚ the old Simon and Garfunkel version‚ or the newer version by Disturbed? Why? I like the newer musical version redone by the group called Disturbed. Because the lyrics have a modern twist‚ and the words are very clear somewhat haunting. I did not get the feeling from the Simon and Garfunkel original version the words were not very clear. Disturbed’ s band was a full orchestra band which made the
