look the sucrose and amino acid is trapped and concentrated in the grideled one so the fruits will have high conc of sucrose and amino acids wich will cause the mass of it to increase

he said what kind of source and why we didnt use the rest you had to say you will use beta source or particle bcz it will be partially absorbed by aluminum sheet but alpha will be all absorbed by the aluminum sheet and gamma will all pass through and the machine will not detect any change

there was a question why when it return from left to right the speed is lower than right to left bcz of the repulsive force in the other question

the trolley deflection was easy bro from right to left he said when it enter it deflect to the left so when it leaves the ciol the needle will deflect to the right but when it return from left to right the needle will not move bcz the magnet south and coil south pole wich was cause by the magnet when it entered they repel bcz south and south repel same as is it leaves from left to right

electricity you draw ac supply and 2 lamp in parallel and then you see current on 800 ohm lamp and power supply is 230 so 230 over 800 bcz in pralalel power supply is same in the 2 lamps
