ECAT and MCAT Preparation: Post your doubts here!

Too generalistic!
we have to substitute for l and b and h.




wrong

we know height of square prism = height of cylinder
but we have to find base area of square
volume of square prism = base area * height

yes I know the formula ..... bt fr volume... so did I applied... but if stil ans. is not the same... there could be some minor silly mistakes

A car is moving at 40 m/s on a circular road of radius 400m. The speed of car is increasing at a rate of 4m/s. The resultant acceleration is? A- 5.22 m/s B- 5.66 m/s C- 5.33 m/s D- 5.84 m/s

Ah i got this one no need to explain.

well can anyone here explain or share notes for conic sections, i went through the khan academy videos but the fsc syllabus contains a lot of extra material, the fsc students seriously are at an advantage in these tests

what is the ans exactly? B?

In conic section , Circle and Parabola are most imp.. (Hyperbola and ellipse ) are other topics..

The kinetic energy of a body, varies directly as time t. the force acting varies directly as? A- 1/(t^1/2) B- t^1/2 C- 1/t D- t

How'd it go?

 

[leadingguy]

not toooooooooooo awsome but yes It was good....

one thing I wud lyk to conclude ..... they are tooo miser at alloting time... huh
two essays of 250-300 wrds almost and only 40 minutes
45 english questions in 45 min.

 

[Goodfella]

B- force acting

I wrote the same answer, but the book says D Impulse!

A- 45

can u tell me the reason for it? i mean isn't Cos 30 the maximum value for Cos?

The book is probably wrong about impulse thing. Because impulse is change in momentum. It doesn't depend on time. And about range. Its formula is Range = [(initial velocity)^2/ g] x sin2 theta. 2 times 45 is 90 which gives the maximum value of sine

Omg this is going everywhere no sense of direction in this topic though the idea is good and helpful but I do wish it were more organised in any manner, any ways My question is does anyone know tips or shortcuts that can help in preparation for Ecat??? even if u have any small TIP that u are using please do share
