				   Draw the graph of y=ax - bx^2 where a and b are some positive constants. (please upload the image somewhere and paste your image link in my answer)

7 years ago


Answers : (1)


for y=ax - bx^2   a>0 and b>0

at y=0 we have roots x=0 and x= a/b

and it has maximum at P(as shown in fig.) with  x= a/2b and max value y=a2/4b

The graph is a parabola opening downwards towards -ve Y-axes with roots at x=0,a/b

EXPERTS PLZ HELP ME Is the moment of inertia of disc and ring are (mr 2 )/2 and mr 2 respectively?? and if yes how can the moment of inetial of ring greater than that of disc ??
Yes, its true. The moment of inertia of a disc and a ring about an axis perpendicular to their plane are and resspectively. Here you have to notice in both the cases we are taking the mass...

See the moment of inertia is proportional to r 2, for same mass ,as the mass is concentrated more farther from the ring it will have greater moment of inertia.

a cricket ball is thrown at a speed of 28m/s in a direction 30*( 30 degrees) above the horizontal .Calculate its maximum height.
Here, velocity of projection, u = 28 m/s. Angle of projection, = 30 ০ . We have, maximum height attained by a projectile, So, the maximum height attained by the ball is 20 m. THANKS

It sould be, So, the maximum height attained by the cricket ball will be 10 . Sorry for mistake. THANKS

Sorry, I didn’t understand your question fully. How can we tell just seeing upon magnitudes of the forces without direction. U must provide some direction of forces acting on any object.
