Dear blog,
today was the day i've been afraid of since the first day i entered 'kahraba" its the lab exam of physics.
el 7mdolilah i have to say it went ok, but not perfect so here what happened first b4 the exam there was a circuits lecture and we had to stay there hearing useless grades for each person,
anyway after they released us from our prison i went flying to the lab preparing to my destiny, the guy chooses the paper and playing with your heart and doctors sitting talking and laughing and we are dying "never mind" i got MELD EXP. so i said let's go for it it's easy i went to the exp. and found myself numb. :D
i forgot everything i knew but step by step i started taking readings for the lab then came doctor SAMY and told me what's your last name then he asked me
He: did you read the Q on the bench
Me; Yes
He; so tell me what do you want to measure in this exp.
ME; Frequesncy hahaha
HE:...........
then i realized tht the written Q on the bench tell us to measure mass of the pan :D
HE: is this wave transverse
ME: yes
HE:Why?
ME: direction of propagation prependicular on direction of oscillation
HE: Tab why does this fork vibrate?
ME: i was so nervous so he helped me and pointed at the iron core i said ahh cause this core is like rumkourff coil and it attracts el fork ...............
HE: then this coil is going to be .........
ME: magnetized :D
HE: he said ok can you tell me what's the type of electric source
ME: DC " i looked at the source its written on it :D"
HE: can we use AC?
ME: no we cant cause its frequency will conflict with frequency of fork
HE: ok then tell me what would be the frequency of the fork if the source is AC ............................
ME : :S:S:S::S:S ........................
HE; ok think then tell me then he left :D
ME: continued el experiment
if anyone knows the answer of this Q tell me he told me it wont be an average between the two frequencies,
HE: is this wave transverse
ME: yes
HE:Why?
ME: direction of propagation prependicular on direction of oscillation
HE: Tab why does this fork vibrate?
ME: i was so nervous so he helped me and pointed at the iron core i said ahh cause this core is like rumkourff coil and it attracts el fork ...............
HE: then this coil is going to be .........
ME: magnetized :D
HE: he said ok can you tell me what's the type of electric source

ME: no we cant cause its frequency will conflict with frequency of fork
HE: ok then tell me what would be the frequency of the fork if the source is AC ............................
ME : :S:S:S::S:S ........................
HE; ok think then tell me then he left :D
ME: continued el experiment
if anyone knows the answer of this Q tell me he told me it wont be an average between the two frequencies,
anyway i continued the readings the device was soooooooooooo stupid bas el 7mdolilah i got weight of the pan 45 gm and weight unknown = 52 gm
anyway "HAM WE ENZAAAAAAAAAAAAA7" el 7mdolilah
anyway "HAM WE ENZAAAAAAAAAAAAA7" el 7mdolilah
