i missed the lesson last week, where sir went through that (cause i was sick) and we have a quiz on this tmr
for a, it's velocity of the cyclist divided by the constant acceleration of the bus

for b, use simultaneous equations

for c, use the answer u get for b i think

Just a question for anyone who is doing bio? If you are asked to find the actual size of a cell and they give u a scale bar. Do you do Actual length of scale bar/ measured length of the scale bar. Then you use that scale factor and times it by the measured length of drawing to get the actual cell size. Right? I just need clarification because I feel like I'm doing it wrong

calculate the cell size and then use the scale bar to be accurate (i think)

Yea that sounds right- but if you are still unsure you could go to textbook or chatgpt it-

based on what i've learnt (which is not the most lets be honest), yes it pretty much is just actual length of scale bar divided by the measured length of scale bar and then multiplied by the measured size of the cell
