The international system is followed by most of the countries of the world. In this system, a number is split up into groups or periods. In the Inter-national System of Numeration, we use ones, tens, hundreds, thousands, millions and billions.The 1st period consists of ---> ones, tens and hundred.The 2nd ... Read More

Given: Mass of ice, m = 10 g = 0.01 kg [converted gram to kilogram] Amount of heat energy absorbed, Q = 5460 JSpecific heat capacity of water = 4200Jkg-1K-1 Specific latent heat of fusion of ice, L = ?  Solution: Amount of heat energy required by 10g (0.01kg) of water ... Read More

Negatively-charged electrons can be removed easily from the atoms of conductive materials. When small electric potential is applied, the electrons escape from the atoms and start flowing. A closed circuit of conductive material provides a path for electrons to continuously flow. So, negatively charged electrons are responsible for flow ... Read More

To do: Find what is  $7 \frac{1}{8}$ in decimalSolution:$7\frac{1}{8} = 7 + \frac{1}{8}$From division method $\frac{1}{8} = 0.125$Therefore, $7\frac{1}{8}= 7 + 0.125 = 7.125$So, the option [d] is correct.

Given: Sohan bought 5.730 Kg tomatoes and 3275 g potatoes Rohit bought 3.250 Kg tomatoes and 7335g potatoes To do: Who bought more vegetables and by how much Solution: Sohan bought 5.730 kg tomatoes and 3275 g of potatoes1kg = 1000g so, 5.730 kg = 5.730 $\times$ 1000 g = 5730 g Total ... Read More

Coir is coconut fibre.It is a natural fibre extracted from the outer husk of the coconut.It is used to make products such as floor mats, doormats, brushes and mattresses. 

We can convert a mixed fraction into an improper fraction using the following formula: For example, consider $8\frac{4}{7}$. Here Whole number = 8, Denominator = 7, Numerator = 4.  Substitute in the above formula $8\frac{4}{7}=\frac{(8\times7)+4}{7}=\frac{60}{7}$.

When a metal wire is connected across two terminals of a voltage source with positive and negative terminals, the source develops an electric field across the metallic wire. This field forces negative charge or electrons to flow towards the positive terminal. That negative charge is nothing but current or electricity. ... Read More
