A motion is not possible if there is more friction. When brakes are applied, the friction between the brakes and tires is large enough to not allow the tires to move.

Given :The given expression is $3\frac{1}{5} \div \frac{8}{27} - \frac{2}{21} \times \frac{7}{5}$.To do :We have to solve the given expression.Solution :We know that, $\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}$ $3\frac{1}{5} \div \frac{8}{27} =  3\frac{1}{5} \times \frac{27}{8} $315÷827−221×75=3×5+15÷827−221×75=15+15÷827−221×75=165×278−221×75=2×275×1−2×13×5=545−215=54×3−2×115=162−215=16015=3233\frac{1}{5} \div \frac{8}{27} -\frac{2}{21} \times \frac{7}{5} =\frac{3\times 5+1}{5} \div \frac{8}{27} -\frac{2}{21} \times \frac{7}{5} =\frac{15+1}{5} ...

Given :The given expression is $1234 \times 567-234\times 567$.To do :We have to simplify the given expression.Solution :The distributive property of multiplication states that when a factor is multiplied by the sum or difference of two terms, it is essential to multiply each of the two numbers by the factor, ...

A wheel reduces friction by allowing the contacting surfaces to roll rather than to drag or slide over each other. When wheels are used, rolling friction starts acting instead of kinetic friction. Thus the frictional force acting on the wheel would be less. Therefore, because of less friction, to travel ... Read More

Biosynthesis is an enzyme-catalyzed reaction in which substrates are converted into complex products within living organisms. For example nucleic acid synthesis, amino acid synthesis, and ATP synthesis.

The division is a method of distributing a group of things into equal parts. It is one of the four basic operations of arithmetic, which gives a fair result of sharing. The division is the inverse of multiplication.We use the ÷ symbol, or sometimes the / symbol to mean divide: 20 ... Read More

Uniform Motion- This type of motion is defined as, if a body travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time, no matter how small these time intervals may be. If we draw a distance-time graph for ... Read More

Vinegar is acetic acid in water so it would be exceptionally difficult to separate vinegar and water. Acetic acid usually makes up only 3 - 4% of a typical retail vinegar and the rest is water itself.However, if you are want to separate the acetic acid from water then careful ... Read More

22=4, 42=16, 62=36, 82=64, 102=100.2^2=4, 4^2=16, 6^2=36, 8^2 =64, 10^2=100. Given :Two sets of squares are given.To do:We have to find which of the given numbers are squares of even numbers and odd numbers.Solution :Square of even number always ends with 2, 6, and 4.$2^2 = 4, 4^2 = 16, ...

The Tyndall effect is referred to the phenomenon in which light is scattered by particles in a colloidal solution or in a very fine suspension. It can be seen when the light passes through the colloids or turbid substances causing the light to scatter in multiple directions. Example: On a ... Read More
