I know itlook at the scale again
its n0t 1,2..
but 2,4..
but the answer will be 1.6 not as how MS says 3.2

He already gave explanationI know it
but the answer will be 1.6 not as how MS says 3.2
I did not get you, what you wanted to sayWhat does peak ( progressively ) smaller mean .. progressively is underlined in MS
this is a2 pprI did not get you, what you wanted to say
woops! Scarred.this is a2 ppr

Check If I did any mistakes..Q2 it can't be A and B as ohms and watts are not base units
now we have C and D
We know Power=Voltage*Current
Making Voltage the subject Voltage=Power/current
there is another formula saying power=energy/time
so now we have voltage=energy/time*current
another formula says energry=mgh,0.5mv^2.......... i will use mgh
so now we have voltage=mgh/time*current
g is ms^-2<-- from SI BASE units of acceleration=v/t
now we know the base units of
mass=kg
g=ms^-2
h=m
time=s
current=A
lets put it in voltage=mgh/time*current
Volts=kg*ms^-2*m/A*s
Volts=kg*m^2*s^-3*A^-1
7. P is 1/6 OF Earth
earth is 9.81 or whatever the value given in that year
so P=1/6 * 9.81 this will give g(The acceleration of free fall)on P
The acceleration of free fall on P=1.635
Weight=Mass*Gravity
Weight=30*1.635=49.05
this is planning question! You have to plan how you would carry it out.they would give you the apparatus so you will decide like that. if you send me the confidential instructions of that year i can tell you how it has to be done. ok?
well i only just did 2Check If I did any mistakes..
But seeing my solutions.. Was I correct on which I took an attempt ?well i only just did 2
totally correctBut seeing my solutions.. Was I correct on which I took an attempt ?
The rest I was not able to solve plz all of u help me and himtotally correct

tyThe rest of these questions answeers.
Q14- anticlocwise moment = clockwise moment
W*2a = W*a + F*h
Q-25 P is displacement. that is obvious. while finding q look at the axis.. the TIME is on the x axis. so its frequency
Q-27 Antinode. that word is specifically given. so its lamda/4.
so lamda/4 = x
4x = lamda
4x = speed/frequency
make f the subject
f = c/4x
Q-28 d sine theta = n*lamda
where d = 1/N
so 1/N sin theta = n*lamda
where n = 3
make sin theta the subject, ull get the answer.
