haruspex: Correct, the length of the pipe gradually increased. I know that in the pipe, it's a standing wave, right? Since the frequency of the waves are the same. I know that when the waves are aligned it is constructive interference, and destructive interference on the flip side. I'm just...
Homework Statement
Hey guys, doing a lab in where we are analyzing a standing wave inside of a pipe. We recorded data points as we pulled out this tube where we saw the amplitude of the wave reach maximums and minimums (this was with using 2000 Hertz first and 1000 Hertz next)
In the...
Homework Statement
I'm doing a lab, and they want me to show the dependence of the period on different variables (displacement, mass, and length of pendulum). They ask me to "Fit curves to your plots to show the dependence. Use the curve fits from your plots to devise an equation for...
Homework Statement
Hey all - I'm doing a physics lab on rotational motion, and I can not make sense of the last part, the additional analysis. The question is:
Since our masses are not actually point-masses, the theoretical model I = MR^2 is not very accurate, so for a better theoretical...
Homework Statement
A 990-kg race car can drive around an unbanked turn at a maximum speed of 42 m/s without slipping. The turn has a radius of 140 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of 12000 N on the car. (a) What is the coefficient of...
Homework Statement
Im doing a lab report, and in the analysis section it asks: -Using Newton’s 2nd Law and the free body diagrams, calculate the theoretical value for the tension in the string and the acceleration of the system. (You should get two simple simultaneous equations which you...
Homework Statement
A quarterback claims that he can throw the football a horizontal distance of 193 m. Furthermore, he claims that he can do this by launching the ball at the relatively low angle of 32.1 ° above the horizontal. To evaluate this claim, determine the speed with which this...
