Astudent is examining a bacterium under the microscope. the e. coli bacterial cell has a mass of m = 0.900 fg (where a femtogram, fg, is 10^−15g) and is swimming at a velocity of v = 2.00 μm/s , with an uncertainty in the velocity of 3.00 % . e. coli bacterial cells are around 1 μm ( 10^−6 m) in length. the student is supposed to observe the bacterium and make a drawing. however, the student, having just learned about the heisenberg uncertainty principle in physics class, complains that she cannot make the drawing. she claims that the uncertainty of the bacterium's position is greater than the microscope's viewing field, and the bacterium is thus impossible to locate.

what is the uncertainty of the position of the bacterium? express your answer with the appropriate units.

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called

In a heat engine if 1000 j of heat enters the system the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2000 j? 1. write the equation 2.list out your known variables 3.plug the numbers into the equations 4.solve 5.write your solution statement that includes initial energy and final

The junction rule describes the conservation of which quantity? note that this rule applies only to circuits that are in a steady state.
