Statements:Earth dams are gravity dams.No gravity dam is an arch dam.Some earth dams are embankments.Some embankments are hollow.Conclusions:I. Some gravity dams are embankments.II. Some embankments a

Force of gravity on Jupiter is Earth's

Consider the following statements relating to the stability of floating as well as submerged bodies :1. A submerged body is stable when the centre of gravity is below the centre of buoyancy.2. A float

When equal volumes of two substances are mixed, the specific gravity of mixture is 4. When equal weights of the same substances are mixed, the specific gravity of the mixture is 3. The specific gravit

An alloy is prepared by mixing equal volume of two metals. The specific gravity of alloy is 4. But when equal masses of two same metals are mixed together, the specific gravity of alloy is 3. The spec

A solution of specific gravity 1 consists of 35% A by weight and the remaining B. If the specific gravity of A is 0.7, the specific gravity of Bis

A body is raised to a height h so that the force of gravity on body is 1% of the value on the surface of Earth. If the radius of the Earth is 6400 km, then the value of h is

A planet has twice the density of Earth but the acceleration due to gravity on the surface is same as on the surface of Earth. Its radius in terms of the radius R of Earth is

The ratio of the radius of the Earth to that of moon is 10. The ratio of acceleration due to gravity on Earth and on Moon is 6. The ratio of the escape velocity from the surface of Earth to that from

In orthogonal turning of a bar of 100 mm diameter with a feed of 0.25 mm/rev, depth of cut of 4 mm and cutting velocity of 90 m/min, it is observed that the main (tangential) cutting force is perpendi
