Because quantum mechanics is physics that describes the interactions of very small objects (i. e. molecules, atoms, and electrons), this week you will need to know how to multiply very small numbers. remember that scientific notation writes very small or large number in terms of powers of 10. for example, .0008 can be written in scientific notation as 8 x 10-4 or as 8e-4. the power of 10 (-4 in this case) tells you to take the number 8.0 and move the decimal 4 places to the left giving us .0008. which is a correct representation of .000025 in scientific notation?

The image shows the positions of a car on a roller coaster track. arrange the cars in order based on their gravitational potential energy. begin with the lowest potential energy and end with the highest.

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)

Urgent pls a. coal consumption levels off and remains flat. b. petroleum, natural gas, and renewables show an increase in consumption c. more nonrenewable resources continued to be consumed than renewable. d. there is little projected increase in nuclear energy use. e. carbon dioxide emissions are projected to decline as we approach 2040. global energy consumption is defined as the total energy used by an individual or organizations from around the world. use the graph above to analyze the projected energy consumption from now until 2040. which statements in the prompt apply? a) a, b, d b) b, c, d c) a, c, d d) a, b, c, d
