Speed and travel time are Inversely Proportional because the faster we go the shorter the time. As speed goes up, travel time goes down And as speed goes down, travel time goes upThis:y is inversely proportional to x Is the same thing as:y is directly proportional to 1/x Which can ...
(a) Ratio of work functions ϕ1:ϕ2:ϕ3=1:2:4 (b) Ratio of work functions ϕ1:ϕ2:ϕ3=4:2:1 (c ) tan θ is directly proportional to hc / e, where h is Planck constant and c is the speed of light (d) The violet colour light can eject photoelectrons from metals...
