The magnetic field is directed into the page, and the electron had an initial velocity of 2.7 × 10° m/s. (a) If the initial radius of the electron's trajectory is 5.0 cm, what is its velocity when it has spiraled in to have a path with radius 2.0 cm? (b) What is the correspond- ing change in kinetic…

-Screen reader description: The Ordinary Phases of Carbon Dioxide. Pressure (Pa) 10 to the power of 0 to 10 up to 10 to the power of 8 on Y-axis. Temperature in Kelvins 0 to 700 on X-axis. Curved line up from 105 K at 10 to the power of 0 Pa up to 200 K and 10 to the power of 6 Pa. The line forks here. There is an almost vertical line up to 10 to the power of 8 Pa, and a line that goes diagonally up and to the right to 325 K and 10 to the power of 7 Pa. To the left of the fork is "Solid". To the right of the fork is "Gas". In between the lines of the fork is "Liquid". End of image. The pressure is decreased slowly from 107 Pa at 150 K. Which of these best describes what is observed? It starts out as a solid, then becomes a liquid, then becomes a gas. It starts out as a gas, then becomes a solid, then becomes a liquid. It starts out as a liquid, then becomes a solid, then becomes a gas. It starts out as a solid, then becomes a…

To determine the density of liquid samples. 2. To form a layer of four given liquid (one on top of the other) according to the density, from bottom up. Apparatus : Platform balance, 1 - 25 mL test tube, 1 - 10 mL graduated cylinder, 2 - mL colored water, 2 – mL coconut oil, 4 pcs. Vials. 2 - mL colored alcohol, 2 - mL kerosene Materials : Theory: Density is best described as the compactness of a substance. The more compact is the substance the in a small space the heavier is the substance. For a less dense substance, the mass is spread out over a large volume of space. It is a measurement of how heavy of light is the substance Its mathematical expression is density is the ratio of an object's mass to its volume. The density of a material…
