A histogram is a pictorial representation of the grouped data in which class intervals and frequency are respectively taken along
(a) vertical axis and horizontal axis
(b) vertical axis only        
(c)  horizontal axis only
(d) horizontal axis and vertical axis.

In a histogram the class intervals or the groups are taken along (a)Y-axis (b) X-axis (c)both of X-axis and Y-axis (d) in between X and Y axis

Find the equation of the ellipse whose centre is the origin, major axis 9/2 and eccentricity 1/sqrt(3) where the major axis is the horizontal axis.

A particle P is to be projected from a fixed point A on the ground with a fixed speed u . Another particle Q is also to be projected from a point B which is directly above the point A . The trajectory of the particle Q touches all possible trajectories (for different angle of projection) of the particle P in the vertical x-y plane. Find the equation of trajectory of the particle Q . (Take the point A as origin, horizontal axis x- axis and vertical axis y- axis Consider the figure.)

Find the equation to the ellipse with axes as the axes of coordinates. major axis 9/2 and eccentricity 1/sqrt(3) , where the major axis is the horizontal axis,

Dip circle can be used to determine the angle of dip at a place . Dip circle consists of a magnetic needle free to rotate in a vertical plane . The end points of the needle move over a vertical circular scale . This arrangement can rotate about vertical axis . The angle rotated about vertical axis can be read from a horizontal scale . If a dip circle is further rotated about vertical axis by 60^(@) then the apparent dip at that position will be

A uniform of mass m and length L is tied to a vertical shaft. It rotates in horizontal plane about the vertical axis at angular velocity omega . How much horizontal force does the shaft exert on the rod?

Which two orbitals are located along the axis, and not between the axis?

Name any two letters of the English alphabet which have: a. only horizontal line of symmetry b. only vertical line of symmetry c. both horizontal and vertical lines of symmetry.

Pressure gradient in the horizontal direction in a static fluid is represented by (z-direction is vertically upwards, and x-axis is along horizontal, d is density of fluid):

The vertical component of a vector is equal to its horizontal component. What is the angle made by the vector with x-axis ?
