Your grade?My grade or the gt?
An A*, InShaaAllahYour grade?
yeah i got something similar for rms i think. What did you use to calculate acceleration?i got 4.3 x10^4 and 5.3 x 10^4 for rms and acceleration got like 4 point something to the power 27
i got 1370 and 1670 for rms loli got 4.3 x10^4 and 5.3 x 10^4 for rms and acceleration got like 4 point something to the power 27
yep i did tht and got a really big answer hope its correct. did u do the derivation of p=(2mqV)^0.5used colounbs law then F=ma where m was 2u
ya and then we had to multiply both sides by m right. thts what i did lol. and y was the shm question 6 marks what did we have to explainyea it is correct makes sense if
its a big value cause they tend to have bug accelerations yea i did that using 0.5mv^2 and Vq
Explain? Wasn't the 6 mark a calculation question?ya and then we had to multiply both sides by m right. thts what i did lol. and y was the shm question 6 marks what did we have to explain
yes it was but the calculation was only 2 steps and it said to explain the answerExplain? Wasn't the 6 mark a calculation question?
lol idk i even explained y the oscillations decrease which i think was totally irrelevant. btw in the light intensity question, the light intensity had to be lower right in order for the lamp to lightyea you multiply by m i guess you just had to state formulas of omega and the energy and i think it had to be detailed
Yes it had to be lower so more resistance of LDR ,more p.d across LDR and hence less p.d across the inverting input. So non-inverting is greater than inverting and output will be positive so diode will allow current to pass to relay.lol idk i even explained y the oscillations decrease which i think was totally irrelevant. btw in the light intensity question, the light intensity had to be lower right in order for the lamp to light
got it rightyea exactly that
what boxesin that electronics question, what did you write for the 2 boxes?
in the question before the attenuation one, where you had a microphone connected to a speaker with electronics inbetween.what boxes
I think it was 44 or something. I said kinetic energy of products and as e.m radiation as gamma photons. What did you write?Hey what was the ratio of input power to noise, and in the very last question what is the energy released in a fission reaction converted to?
So what was your answer for that question?Centripetal force is provided by gravitational force, the centripetal force accelerates the object towards the center and so it is kept in circulat motion, for the very last question the energy releases is in the form of kinetic energy, but the question is about what the energy released is CONVERTED to, not what form it takes.
