Diameter was given if i'm not mistaken lol.using s=r(theta) would give circular length. we had to find its diaameter, right?

it wasnt given. :ODiameter was given if i'm not mistaken lol.
Oh ya. haha. I calculated it instead == Because the angle in degrees is very small, just use circular length formula.it wasnt given. :O
we had to find the minimum diameter of a crater, that could be seen using that telescope.
so i did it wrong?Oh ya. haha. I calculated it instead == Because the angle in degrees is very small, just use circular length formula.
but we had to find the diameter, not that circular thingy. so you did it wrong. hehe.Its also because the hypotenuse and adjacent sides of a triangle are always of similar lengths whenever we are dealing with angles that are "not very large"
it was worth only 3 marks.greater than 10 degrees??? I'm not so sure about that
I am right. The arc length is almost equal to the diameter at very small angles. I remember the angle was in the order of 10^-6radiansbut we had to find the diameter, not that circular thingy. so you did it wrong. hehe.
yes, you're right probably.I am right. The arc length is almost equal to the diameter at very small angles. I remember the angle was in the order of 10^-6radians
thats exactly what i wrote.Comment on student's suggestion: coil is stationary, so no induced emf or current to calculate magnetic flux density
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.
