If several satellites are spaced around the same orbit in space, the tracks of the satellites will be different due to Earth's rotation about its own axis. But if, for example, four satellites are placed into different orbits with their ascending modes displaced successively by 30 interv..

All the carbonates of alkali metals are quite stable towards heat except Li 2 CO 3 , which decomposes easily on heating. The instability of Li 2 CO 3 is due to the small size of lithium ion, which cannot stabilize the bigger carbonate ion. The carbonates of alkaline Earth metals are les..

The constituents of the earth are shown in the circle graph. What percent of the earth is covered with water? => 70 or 50 or 60 or 80..

The mass of Earth is 1 / 318 of the mass of Jupiter. Write the decimal for the fraction. => 0.003 or 0.004 or 0.002 or 0.001..

The diameter of the Jupiter is about 22 times the diameter of the Earth. If the diameter of the Earth is around 7,954 mi., what is the diameter of the Jupiter? => 7,954 mi or 1,000 mi or 10,000 mi or 174,988 mi..

The ratio of the mean distance of the Mars from the Sun to the mean distance of the Earth from the Sun is 3 : 2. If the mean distance of the Earth from the Sun is 240 million miles, then what is the mean distance of the Mars from the Sun? => 240 million miles or 300 million mile..

The ratio of mean distance of the Mars from the Sun to the mean distance of the Earth from the Sun is 3 : 2. If the mean distance of the Earth from the Sun is 240 million miles, then what is the mean distance of the Mars from the Sun? => 240 million miles or 420 million miles or..

A model of the solar system is displayed in a planetarium. A sphere with diameter 9 feet represents the Sun. The diameter of the Sun is 109 times the diameter of the Earth. Estimate the diameter of the model represented as the Earth. => 2.1 inches or 1.9 feet or 0.9 inches or 0...

The mean distance of the Earth from the Moon is about 384,400 km. Write this number in scientific notation. => 3.844 x 10 7 or 3.844 x 10 6 or 3.844 x 10 5 or None of the above..

By Avogadro's hypothesis, the actual volume occupied by the atoms in one gram of a substance is 2/3 r d of the volume occupied by 1 gram of the substance. Let us consider a sample of a substance of mass m and volume V. If M is its molecular weight and Avogadro number is N, then Where r = ..
