maybe...related to short circuit..if lamp goes outwhat is meant by lamp is shorted ?
Its a standing wave, so the 33cm is the distance between two nodes. The wavelength thus becomes .66m. F = 330/. = 500. T = 1/500 = 0.002s = 2ms. B is the right answermaybe...related to short circuit..if lamp goes out
igot the same calculated results bt how did u conclude tht its b ..cn u explain fully plx?Its a standing wave, so the 33cm is the distance between two nodes. The wavelength thus becomes .66m. F = 330/. = 500. T = 1/500 = 0.002s = 2ms. B is the right answer
usama321 thank you
usama321 help her.igot the same calculated results bt how did u conclude tht its b ..cn u explain fully plx?
24 you are given the spring constant the firmula for spring constant is K=F/e
where K is the spring constant F is the force and e is the extension
as the trolley is that rest the force applied by P = force by Q
Force by P=k*e=60*0.40=24
Force by Q=k*e=120*e=24
e=24/120=0.2
Do you know the correct answer?Can anyone explain me this question???? I would really be grateful....
even m cnfused in it... :/thanks wat abt question 2 d ii)?
The calculation shows that it takes 2 ms for one wave to complete its cycle. Now each square on the horizontal axis respresents 0.5ms. Thus dividing 2/0.5, it must take 4 complete squares for the wave to complete on cycle. That happens only in Bigot the same calculated results bt how did u conclude tht its b ..cn u explain fully plx?

even m cnfused in it... :/
THIS IS THE 3rd TIME I AM POSTING THIS QUESTION SOME ONE PLZ ANSWER THIS QUESTION with explanation wont take more than 2 min
Is the answer C?Can anyone explain me this question???? I would really be grateful....
Is the answer C?
Note: I am not complete sure about this question
extension = F * l/A*young modulus
Now in the model, all the linear dimensions are one tenth.
Now, the length, width and height of the load are 10 times the one in the model. Thus 10*10*10 = 1000 times the volume of the load in the figure. As volume and mass are directly proportional, the mass should also increase 1000 times, and so should the weight.
Now, the radius of the wire in the model is times the one in the model (linear dimensions) Thus the area should be 100 times more than the one in the model due to the square in the area of a wire
The length of the wire would just be more by a factor of 10.
The young modulus should not change, as it is the same for a material
(1000 * 10/100)/1 = 100
Kindly confirm about this one.
Do you know the correct answer?
It should be B.
On model all lengths are one tenth. So if there is extension of 1 m on real crane there would be a extension of 0.1 m on the model because 1/10 = 0.1
Dividing 1 by 0.1 results in 10 which is the same as 10 raised to power 1.
Just a guess.
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.
