Here is a link to Desmos Here is another formula that we used that is slightly different than the one in the formula sheet above   If a vehicle is moving at mach 0.75 through air at standard pressure and 11 degrees Celsius, while emitting a siren with a frequency of 500Hz from the perspective of an observer that is stationary relative to the siren, solve for the frequency that would be heard from an observer that is a) in front of the vehicle b) behind the vehicle.    

Here is a link to Desmos Here is another formula that we used that is slightly different than the one in the formula sheet above   a) Explain the difference between a transverse wave and a longitudinal wave.   b) If you were to draw a transverse wave to represent a sound wave (as we often did in class), what would the crest of the wave represent?   c) Describe the following terms as they relate to a wave; node, antinode, amplitude       

Here is a link to Desmos Here is another formula that we used that is slightly different than the one in the formula sheet above   a) If you are planning on using a string to generate a sound wave, describe two things that you could do to that string in order to change the frequency at which it would resonate.    b) If a closed air column is 1.75m long and it is in a room that is 23 degrees Celsius; find the frequency and the wavelength of the 3rd and 4th harmonics.   c) If a string is resonating in its second harmonic on a 15 degree Celsius  day at a frequency of 550 Hz, how long is the string?      

Design functions like preparation of shop drawings and submittal review should be included in a construction schedule.

To investigate the effects of progesterone priming on follicular wave dynamics and its role in synchronizing ovulation in dairy cows undergoing timed artificial insemination (TAI) protocols. Objective 1: To examine the influence of progesterone priming on follicular wave emergence and dominance in cycling and anovular dairy cows. Hypothesis 1: Progesterone priming will regulate follicular wave emergence, ensuring the selection of a dominant follicle capable of ovulation during TAI. Objective 2: To evaluate the effects of progesterone levels on estradiol production and LH surge timing in cows subjected to TAI protocols. Hypothesis 2: Optimal progesterone levels will enhance estradiol production and synchronize the LH surge, improving ovulation timing and TAI success rates. Objective 3: To assess fertility outcomes, including conception and pregnancy rates, in cows receiving progesterone priming compared to unprimed controls. Hypothesis 3: Progesterone priming will improve conception and pregnancy rates by enhancing follicular readiness and optimizing ovulatory responses. References: Bó, G.A., & Baruselli, P.S. (2014).
