Any tips on phy mcqs like questions posted above there sooooooo hard? How do you tackle these type of qs???
We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

That's a comparator circuit, which basically means that you get an output after comparing the two inputs.
well explained thanks a lotThat's a comparator circuit, which basically means that you get an output after comparing the two inputs.
If V+ > V-, you get +5V as your output.
If V- > V+, you get -5V as your output.
They tell you that non-inverting input is at a fixed 1.0V.
That means, for values >1.0V, the output is -5V and for values <1.0V the output is +5V.
You can already see on the graph that it starts of at 2V and continues till it crosses 1V. For this entire duration, V- > V+, so the output = -5V.well expl
Next, you can see that it goes from 1V to 0V and then back to 1V. For this duration, V+ > V-, so the output = +5v.
Hope any of that made sense, if not just reply to this and I'll try to explain it better.
Since the period is 20ms, it must travel 1/4th of the wavelength in 5ms. Also it should be at it's maximum amplitude so the point should be 1.2/4= 0.3 on the x-axis and 5mm on the y-axis.
Terminal velocity occurs when the weight of an object is equal to the air resistance acting on it. An object with smaller mass has lesser weight and hence less air resistance will be required to achieve terminal velocity. Your explanation is correct.9702/22/M/J/11 Q2(b)(ii)
A second raindrop has a radius that is smaller than that given in (a). On Fig 2.1, sketch the variation of speed with time for this second raindrop
The sketch is below the original curve
Is it because the radius is smaller therefore the mass is smaller as well (since p=mv) so it reaches terminal velocity earlier?
The two changes that will occur will be the change in speed of the meteorite since the combined gravitational field of both will cause the meteorite to accelerate and also the meteorite will deviate from the path it would have followed otherwise in the absence of the second field.
can u draw and show itSince the period is 20ms, it must travel 1/4th of the wavelength in 5ms. Also it should be at it's maximum amplitude so the point should be 1.2/4= 0.3 on the x-axis and 5mm on the y-axis.
Im not sure if it would be drawn like this. What does the MS say?can
can u draw and show it
Gain = V out / V in -----------> V out = V in x Gain -------> V out = 95x10^-3 * 71 = 6.75 VPart c anyone?
And then you can find the combined resistance : (1/24+1/12)^-1 = 8 ohmView attachment 60136
Can anyone tell me steps
Definitely giving AS is better. Even though I don't have the experience but I'm pretty studying for both the courses at the same time is going to be very tough.i have qtn...is giving AS better or giving the complete A LEVEL is better....
EVERYONE PLEASE POST UR OPINION
thanks in advance
It depends from person to person. I had a friend who gave 6 subjects in 6 months and scored 6A*s and a friend who is giving just As level since 2 years and yet he is stuck at D. So now as I said, it depends. If you love studying and your complete focus is in studies and wanna score good u need to practice heck so muchhhhhhhhhhhhhhhhhhhhh!!i have qtn...is giving AS better or giving the complete A LEVEL is better....

For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
