In a Carnot's cycle, if $V_1$ and $V_2$ are respectively the initial and final volumes of the working substance during isothermal expansion process, $V_3$ and $V_4$ are respectively the initial and final volumes of the working substance during isothermal compression process, then the relation among $V_1, V_2, V_3$ and $V_4$ is
A thin convex lens forms a virtual image when an object is placed on the principal axis at a distance of 12 cm from the lens. When the object is moved away from the lens along the principal axis through a distance of 18 cm, the lens forms a real image. If the magnification of the virtual image is five times the magnification of the real image, then the focal length of the lens is
The acceleration due to gravity at a point A at certain height from surface of the earth is $\frac{g}{4}$ where 'g' is acceleration due to gravity on the surface of the earth.
