You visit your friend and find her in her kitchen with a rubber ball and a bucket of ice water conducting an experiment. When you ask her what she is doing this is what she says: "I wanted to know if how high a rubber ball bounces is affected by its temperature so I'm dropping the ball a few times, then cooling it down with the ice water and dropping it again." Which of the following best describes the kind of experiment your friend is conducting and why? It is an observational experiment because it is entirely qualitative (no measurements are being taken). It is an observational experiment because your friend is trying to learn more about a phenomenon. It is a testing experiment because your friend is actively participating in the experiment. It is a testing experiment because your friend is testing the relationship between between temperature and bounce height.

Magnetic Field Of Coaxial Cable

The word coaxial means same axis. So for a long straight cable to be coaxial, it must have concentric cylindrical shaped conductor around it. Coaxial cable (popularly called ‘coax’) has various applications ranging from current conductors to radiofrequency signal transmitters. This cable has lower emission losses and provides protection from electromagnetic interference which allows signals with less power to transmit over longer distances.For example, currents produced in the pickup of a stereo turntable generally travel to the amplifier through a coaxial cable.The self-inductance of a coaxial cable is another important characteristic, because it influences the propagation of electrical signals in the cable.

Hector read that the traditional drink in Tibet is tea with added butter. Inspired by this idea, he decides to investigate how a thin layer of fat on the top of a hot liquid affects the cooling of the liquid. He performs two different experiments.Experiment 1: Hector pours 100 mlml of boiling water into each of two Styrofoam cups and adds a thin (2.0-mmmm) layer of hot oil (at about 100∘C∘C ) to one of the cups. He measures the initial temperature in the cups, waits for 10 minutes, and then measures the temperature again. His measurements are shown below. Cup A(no oil) Cup B(with layer of oil) TiTi 98∘C∘C 98∘C∘C TfTf 84∘C∘C 95∘C∘C Experiment 2: Hector puts two empty Styrofoam cups on separate precision scales and zeroes the scales. Then he pours 100 mlml of boiling water into each cup and adds a 2.0-mmmm layer of hot oil to one of the cups. He records the initial readings of the scales, waits for 10 minutes, and then records the readings of the scales again. His data…

The cube quickly comes to rest on the bottom surface of the container. The bottom surface is maintained at a constant temperature 0 (note that this is different from 0w). The thermal resistance between the cube and the water is Rcw while the thermal resistance between the bottom surface of the container and the cube is RCB.
