1. ### Working out the intercept of the Y-Axis

If a gradient of -578.947 is present on a line of best fit then how can you work out the intercept of the Y-Axis when a co-ord of: (0.00000227, 0.00100) is given? Thank you
2. ### Finding out internal resistance of a lemon when used as a power supply

Hi There, Right I recently did an experiment in Physics to find out the internal resistance of a lemon when used as a power supply. We connected the lemon to a voltmeter, ammeter and variable resistor, changed the resistance on the variable resistance and measured the voltage and current...
3. ### Stress in rope with pulley and weight

So would that surfice to go on and work out the young modulus of that fishing line seeing as i already have the strains? I thought you may have had to work out the cross sectional area of the fishing line and multiply by the length to find the entire area of the fishing line, but i think you...
4. ### Stress in rope with pulley and weight

Homework Statement Im trying to work out the stress of a fishing line after connecting a fishing line to a pulleyboard and adding 100g weights one at a time onto the fishing line to create strain and stress. I know the formula is Stress = Force divided by area And i have already worked...
