The drawing shows two transverse waves traveling on two strings. The linear density of each string is 0.0606 kg/m, and the tension is given by a 20.6-N block that is hanging from the string. Decide the speed of the wave in part (a) and part (b) of the drawing.
you make five measurements of a particular wavelength and you find you have some random noise. your measurements are
Two newly discovered planets follow circular orbits around a starin a distant part of the galaxy. The orbital speeds of the planetsare determined to be 44.3 km/s and 60.5 km/s. The slower planet'sorbital period is 7.03 years.
