tsunamis are fast-moving waves often generated by large underwater earthquakes. in the deep ocean, their amplitude is barely noticeable, but upon reaching shore, not complete marked out ofwhat is the speed of the wave? they can rise up to the astonishing height of a sb-story buiding. one tsunami, generated off the aleutian islands in alaska, had a wavelength of 730 km, and travelled a distance of 3830 km in 6 30 hours (note: this is given in decimal format, not as hours and minutes). 1.00 m/s ,flag question check question 7what is the period of the wave? not complete marked out of 1.00 , flag question check

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.

Arod of some material 0.20 m long elongates 0.20 mm on heating from 21 to 120°c. determine the value of the linear coefficient of thermal expansion [in (degrees c)^-1] for this material.

Scout feels ill one day before school. her mother puts a thermometer in her mouth and the temperature begins to climb to 100°f. what is happening between the cooler thermometer and scout's body? a) scout's body is applying a force to the particles in the thermometer. b) kinetic energy is being transferred from her mouth to the thermometer. c) potential energy is being lost by the thermometer and gained by scout's body. d) the potential energy stored in foods is converted to mechanical energy to raise the mercury in the thermometer.
