Humidity is the concentration of water vapour present in the air. The more water evaporates in a given area, the more water vapour rises into the air, and the higher the humidity of that area is. Hot places tend to be more humid than cool places because heat causes water ... Read More

The differences between Kinetic Energy and Potential Energy are as follows:- Basis for Comparison Kinetic Energy Potential Energy Definition It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. It is the stored energy in an object or system ... Read More

Kinetic EnergyIt is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.Kinetic energy can be transferred from one moving object to another, say, in collisions.The SI Unit of kinetic energy is Joule (J).The formula of Kinetic Energy is given as-$K.E=\frac{1}{2}m{v}^{2}$where, ... Read More

Potential EnergyPotential Energy is the stored energy in an object or system because of its position or configuration. It cannot be transferred. The SI Unit of potential energy is Joule (J). The formula of Potential Energy is P.E. = mghwhere, m = mass, g = acceleration due to gravity, and ... Read More

Silkworm primarily feeds on mulberry leaves.Silkworms are the larva of a moth that spins a cocoon of fine, strong, lustrous fibre that is the source of commercial silk. The culture of silkworms is called sericulture.

Double bar graphs, also called double bar charts, help us to compare or present more than one kind of information, situations, or events instead of just one by using bars.To construct a double bar graph:1. Decide what title you will give the graph.2. Decide if you want horizontal or vertical ... Read More

Given:  The cost of 1kg of rice is  Rs.36$\frac{1}{2}$ To do: Find the cost of 4$\frac{1}{2}$ kg of rice Solution: Cost of 1 Kg of Rice = .36$\frac{1}{2}$                                     = Rs 36.50Cost of 4$\frac{1}{2}$  or 4.5 Kg of Rice                                    = Rs 36.50 $\times$4.5 Kg                                    = Rs 164.25Therefore The cost of 4$\frac{1}{2}$ kg of rice is Rs164.25

A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, 4, and so forth. For being manipulated, individual numbers need to be represented by symbols, called numerals; for example, "5" is a numeral that represents the number five.We ... Read More

Chemical changes occur when a substance combines with another to form a new substance, it is also called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions. Characteristic of Chemical Changes are:1. Change is permanent.2. New substances are formed with entirely ... Read More

Reflection is the change in direction of a wave at a boundary between two different media so that the wave moves back into the medium it came from.The most common examples include the reflection of light, & sound. For example, Let’s see the reflection of light When a ray of light ... Read More
