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
