The table shows the diameters of the planets in our solar system. Assume that a basketball whose diameter is 25 centimeters represents the planet jupiter. Find the scale (ratio) between jupiter and the basketball. Then use this ratio to find the scaled diameter of the other planets. Enter these numbers into the table. (Saturn has been done for you.) finally choose a real world spherical or nearly spherical object that matches the scaled diameter of each planet. Saturn is shown as an example. To find what saturns size would be after adjusting it to scale, follow these steps. Let the scaled diameter of saturn be d centimeters. If jupiter’s diameter, 142,984 kilometers, is scaled to 25 centimeters, Saturns diameter of 120,536 kilometers will be scaled to about 21 centimeters.

Air is held within a frictionless piston-cylinder container, which is oriented vertically. the mass of the piston is 0.45 kg and the cross-sectional area is 0.0030 m2. initially (state 1) the pressure of the gas is sufficient to support the weight of the piston as well as the force exerted by the atmospheric pressure ( 101.32 kpa). the volume occupied by the air within the cylinder in state 1 is 1.00 liter. one end of a spring (with spring constant k = 1000 n/m) is attached to the top of the piston, while the other end of the spring is attached to a stage that can move vertically. initially the spring is undeflected and therefore exerts no force. then the stage is then moved quasistatically downward a distance of 10.0 cm, at which point the system reaches state 2. the piston-cylinder is not insulated; rather it remains in diathermal contact with the surroundings, which are at a constant temperature of 300 k. what is the change of pressure within the container?

Which of the following are considered noble gases? a. bromine b. neon c. argon d. chlorine
