What is the mass (in kg) of {eq}3.2\ L {/eq} of {eq}\rm Br_2 {/eq}?Density:The density of a substance is the mass per unit volume of the space it occupies. It is calculated by dividing the mass of the substance by its volume.Answer and Explanation: Density is given by: ...
of death principle is why Earth is not sucked into the Sun by Gravity. It is also the reason why stars aren't sucked into the supermassiveblack holes at the centres of galaxies. The stars in the galaxies orbit around the centre of thegalaxy. If you had thought the Sun was static in ...
What is the Gram? The gram is a unit of mass (acceptable for use as weight on Earth) and is a multiple of an SI base unit with the symbol g. Although without a prefix, it actually represents 1/1000 kg. It is the first subdivision of the SI base unit; kilogram and 100 g equals...
Given that , Mass of the body ,m=1 kg Mass of earth m=6xx10^(24) kg Radius of the Earth , R=6.4xx10^(6) m Now , magnitude of the gravitational force (F) bettween the earth and the body can be calculated F=G(Mm)/(r^(2))
