Dominic made the table below to organize his notes about mixtures. what mistake did dominic make? the title should read “properties of solutions” because some mixtures do not have all of the properties listed. there is a definite recipe to make each mixture, so the composition of a mixture is set. although it is possible to have more than one state, it is also possible to have only one state. a single substance can be used to make a mixture if the substance is composed of more than one element.

Carbon-14 is a radioactive element that undergoes beta decay. which force is responsible for allowing carbon-14 to become stable? electromagnetic gravitational weak nuclear strong nuclear

1. consider the case in which air fills air shocks on a truck trailer. the pressure in the shocks is 2 mpa. the temperature is 300 k. the diameter of the shock piston is 10 cm and the initial length of the cylindrical cavity containing the compressed air is 40 cm. a. the truck is gradually loaded over a period of a day in a static setting. the temperature is held constant for the atmosphere and thus for the gas shock. calculate the compressibility of the air in the shock for this condition when the truck is initially being loaded. b. if the shocks were loaded in a dynamic setting by driving over bumps, what would be the compressibility? state your assumption. c. what is the initial load on the shock if the shock is in an atmospheric 100 kpa? d. if the shock is compressed using the process described in part a, and the air shock compressed air cavity length decreases to 20 cm, what is the additional load applied to the shock?

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative
