(A) find the mass of a solid steel cube of side 10cm
(B) what volume of the stem has a mass 8kg
The relative density of steel is 7.8 find the mass ofa solid steel cube of side 10cm
R.D=density of substance/density of water.
7.8=density of substance/1g/cm³
°Density of substance=7.8g/cm³
Volume of cube=L³ ie 10cm×10cm×10cm=1000cm³
Density=mass/volume so Mass =Density×Volume
Mass=7.8g/cm³×1000cm³
=7800g
Are you talking about kg/m^3 or g/m^3?

explain the following terms 1) classification 2) binomial system 3) species
1) Classification: It is the process of grouping living organisms based on their similarities and differences. Through the process of classification, we can organize the diversity of life into categories and hierarchies, making it easier to study and understand the relationships between different organisms.
2) Binomial system: It is a system of naming organisms that uses two names – the genus name and the species name – to identify each organism. The binomial system of nomenclature was developed by Carl Linnaeus in the 18th century and is still used today.
3) Species: It is the basic unit of biological classification and refers to a group of organisms that share common characteristics and can interbreed to produce fertile offspring. Species are further divided into subspecies, populations, and other categories based on their physical and genetic characteristics. Each species is given a unique scientific name based on the binomial system of nomenclature.
Distinguish between "the family" in the level of classification of organisms and family as a social group
The term "family" has two distinct meanings and contexts in biology and in human society.
1) Family in the level of classification of organisms refers to a taxonomic rank or category between order and genus. It is a grouping of one or more genera that share common ancestry, characteristics, and evolutionary history. Family is a key level in the hierarchy of groupings in biological classification, which progresses from the broadest categories (e.g. kingdom, phylum, class, order, family) to increasingly detailed and specific classifications.
2) Family as a social group refers to a group of people who are related to each other by blood, marriage, or adoption, and who live together and share their lives and resources. The concept of family in human society is a complex and dynamic one that varies across cultures and contexts, and is influenced by factors such as social structures, gender roles, values, and traditions.
In summary, the term "family" is used differently in biology and human society, with different meanings and applications in these two contexts.
All organisms can be up under five main group using the modern version of classification.
List and support each with appropriate examples
The five main groups of organisms in the modern classification system are:
1. Monera - This group consists of prokaryotic organisms that lack a membrane-bound nucleus. It includes bacteria and blue-green algae, which are single-celled organisms without any complex structure. For example, E.coli, Staphylococcus, etc.
2. Protista - This group comprises unicellular as well as multicellular eukaryotic organisms that are structurally simple. This includes protozoans, unicellular algae, and slime molds. For example, Amoeba, Paramecium, Euglenoids, etc.
3. Fungi - This group contains multicellular eukaryotic organisms that generally have a chitin cell wall and feed through absorbing nutrients from decomposed organisms. This includes mushrooms, yeasts, and molds. For example, Bread mould, Penicillium, Yeast, etc.
4. Plantae - This group comprises multicellular, eukaryotic, photosynthetic organisms that possess a cell wall made of cellulose. This includes flowering plants, bryophytes, ferns, and gymnosperms. For example, Mango tree, Mosses, Ferns, etc.
5. Animalia - This group contains multicellular eukaryotic organisms that lack a cell wall. It includes invertebrates such as insects, spiders, crustaceans, worms and vertebrates like fishes, amphibians, reptiles, birds, and mammals that have a well-defined nervous system. For example, Lion, Deer, Frog, etc.
These five groups provide a fundamental framework for understanding the diversity of life and the relationships between different organisms.
1)Basic units and derived units
2) Scalar quantity and Vector quantity
1) Basic units and derived units:
Basic units are fundamental or base units, and are used to derive other units of measurement. These are the standard units of measurement accepted by the International System of Units (SI), which is the most widely used system of measurement worldwide. There are seven basic units in the SI system, which are length (meter), mass (kilogram), time (second), electric current (ampere), temperature (kelvin), amount of substance (mole), and luminous intensity (candela).
Derived units are units of measurement that are derived from the basic units of measurement. They are created by combining base units using mathematical operations such as multiplication, division, or exponentiation. Some commonly used derived units in physics include velocity (meters per second), acceleration (meters per second squared), and force (newtons).
2) Scalar quantity and Vector quantity:
Scalar quantities are physical quantities that have only magnitude or size. Examples of scalar quantities include time, distance, speed, and mass. These quantities are typically represented using a numerical value and a unit of measurement, but do not have a direction associated with them.
Vector quantities are physical quantities that have both magnitude and direction. Examples of vector quantities include displacement, velocity, force, and acceleration. They are typically represented using an arrow with a numerical value and a unit of measurement, where the direction of the arrow represents the direction of the vector quantity.
