- What is the element with an electron configuration of 1s22s22p63s23p64s23d2?
- rank the following atoms in decreasing atomic radius based on the trends of the periodic table
- which sub level has the most orbitals if the quantum number n=3?
- what kind of force reduces the amount of force needed to do work
- this is the number of times a machine multiplies the effort force
- the part of the lever that exerts a resistance force
- a machine could have no friction and no work energy converted heat energy to heat energy, then work in would equal work out
- the effort force is between the fulcrum and the resistance force
- give an example of a machine that change the direction of applied force to make doing work easier
- A machine that does work with only one movement
- the part of the lever which the effort force is applied
- this can make machines more efficient by reducing friction (Ex. oil or grease)
- a measure of how much work put into a machine is changed into useful output work down by the machine
- a straight bar or rod that can move around a fixed point
- resistance force is located between the fulcrum and effort force
- give an example of force that reduces the amount of force needed to do work
- the fulcrum is located between the effort and resistance force
- A transfer of energy that occurs when a force makes an object move
- do machines increase or decrease the applied force to make doing work easier ?
- give an example of machines increasing the applied force to make doing work easier
