i have been given this question Figure 1 shows a graph of V against I for a filament lamp. Calculate the maximum resistance of the lamp over the range shown by the graph, now i have a somewhat vague attempt and its to measure the tangent of the line (i can't upload the graph sorry) how...

i think i have it now thanks (i found out Newtons second law about 2 minutes before u posted, and the suvat question i just found,) thanks for providing me with support so i avoidied doubting myself

well I'm struggling with a level physics and need some help with a new topic area we're studying the problem is a moving car t velocity of 20 ms(-1) brakes to a standstill in a distance of 40m, a child of mass 15kg is sitting in a forward facing child car seat fitted to the back-seat of...

but how do i find the strain on each with the information given

hello, i am currently going over past exam questions to further my knowledge in as physics when i came across this old question which i don't quite understand, a length of steel and a length of brass are joined together. This combination is suspended from a fixed support and a force of 80n is...

im studying a level physics (after high school, before university) i just find rearranging formula hard

and then fv(squared) = u (v-fv)

erm fv(squared) = u(v-fv)?

so then it would be fv(squared) = uv-fvu?

i actually have no idea

would it be FVU+FV(squared) = UV

er no hah i don't see how my answer is wrong

answer is 14

i don't quite understand that bit

so would it befu+fv+vu+v(squared)=uv
