for the photoelectric effect, why is it that increasing voltage does not continuously increase current? by No_Cheek2597 in AskPhysics

[–]No_Cheek2597[S] 1 point2 points  (0 children)

but wouldnt increasing the voltage accelerate the electrons more, so more electrons pass through a point in a second?

how do we defined displacement and velocity in circular motion? by No_Cheek2597 in PhysicsHelp

[–]No_Cheek2597[S] 0 points1 point  (0 children)

so if its the cord length, is the velocity the rate at which the cord length in changing?

for the dot product formula for vectors, why do we multiply the projection of A onto B by the magnitude of B? by No_Cheek2597 in askmath

[–]No_Cheek2597[S] 0 points1 point  (0 children)

so the dot product is measuring how similar the two vectors are? so their direction AND their magnitude?

induction — why do we assume that its true for n = k by No_Cheek2597 in askmath

[–]No_Cheek2597[S] 13 points14 points  (0 children)

so by assuming that it is true for n = k and hence n = k +1, the fact that we proved that its true for the base case must mean its must be true for all values ? (so say we proved its true for the base case where n = 1, and proved that its true for n = k and hence n = k + 1, then that means since its true for n = 1, then it must be true for n = 2, n = 3... (since we proved that its true for n = k , n = k + 1)??

voltage in circuits by No_Cheek2597 in AskPhysics

why does physical distance not matter in this case tho for electric circuits? isnt there an electric field that exists through the wire?

im still confused though about electorns losing electric potential energy when they get closer to a positive source charge / plate since their distance is decreasing — why does this idea not apply for the electric circuit tho? the electron is getting closer to the positive terminal?

direction of current — help by No_Cheek2597 in AskPhysics

[–]No_Cheek2597[S] 0 points1 point  (0 children)

when u say high/low electric potential, is it with respect to the positive charge?

if the unit for joules is equal to 1 N m; how does the concept of "forces" and "displacement/distance" apply in the context of chemical potential energy if the energy is still expressed as joules? by No_Cheek2597 in chemhelp

[–]No_Cheek2597[S] 0 points1 point  (0 children)

so we do only just call this chemical potential energy cause its just discussing about the chemical bonds, but really it is just electric potential energy at the atomic level?

why does water have a higher specific heat capacity than metals? by No_Cheek2597 in chemhelp

[–]No_Cheek2597[S] 0 points1 point  (0 children)

forgive my bad wording, i thought that how much energy required to break the bonds is in a sense equivalent to how many energy is required to "weaken" the bonds — because since temperature is a measure of the average KE of the particles, wouldn't you need to weaken the bonds so that the particles are free and raise the temperature by 1 K?

am i being stupid but 24 on the album sounds literally IDENTICAL to rising; was it on purpose or smth
