What is the eccentricity of a left hand parabola?

The eccentricity of the parabola y^2 =-8x is :

Statement-I If eccentricity of a hyperbola is 2, then eccentricity of its conjugate hyperbola is (2)/(sqrt(3)) . Statement-II if e and e_1 are the eccentricities of two conjugate hyperbolas, then ee_1gt1 .

Write the eccentricity of the hyperbola whose latus rectum is half of its transverse axis.

Find the eccentricity of the ellipse if : the latus-rectum is one half of its minor axis.

Find the eccentricity of the ellipse if : the latus-rectum is one half of its major axis.

What is the angular velocity of the hour hand of a clock?

A parabola is drawn whose focus is one of the foci of the ellipse x^2/a^2 + y^2/b^2 = 1 (where a>b) and whose directrix passes through the other focus and perpendicular to the major axes of the ellipse. Then the eccentricity of the ellipse for which the length of latus-rectum of the ellipse and the parabola are same is

What is the colour of residue left when ferrous sulphate is heated?

Find the eccentricity of the ellipse if : the distance between the foci is equal to the length of latus-rectum.
