You are holding a string tied to a lamp post 15 m away. You pull the string so that it has a tension of 1.5 N and a mass density of 0.0045 kg/m. You shake the end of the string at 4 Hz. What is the wavelength of the wave you generate in m? You now take three pieces of string from the previous problem and tie two of them together to make a string of double the mass density. You tie the single string and double string together and to two lamp posts that are 40 m apart as seen below. The interface is centered between the posts and the tension is 1.2 N. You briefly shake the string interface at 5 Hz.

By how many seconds does it win the race?

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.
