Pushing a box across the floor is work, so is carrying a box.
</li>
<li>
Holding a heavy box is NOT work because you need to use a force to move an object through a distance. Holding a box does not fulfil the distance requirement.

(a) Total internal reflection is the phenomenon which occurs when a propagated wave strikes a medium boundary at an angle larger than a particular critical angle with respect to the normal to the surface. The critical angle is the angle of incidence above which the total internal reflection occurs. (b) For total internal reflection to occur, two conditions must be met: The index of refraction must decrease across the boundary in the direction of light refraction. The angle of incidence of the light ray must exceed the critical angle of the interface. Ray must travel from denser to rarer medium.

<li>Light scattering depends on the wavelength of the light being scattered.</li>
<li>Thus, limits to spatial scales of visibility arise, depending on the frequency of the incident lightwave and the physical dimension (or spatial scale) of the scattering center, which is typically in the form of some specific microstructural feature.</li>
<li>
<div>However, short wavelengths have lower attenuation, and are thus used in long distance radio signals.</div>

<li>At rest, the lens in the normal eye focuses images of distant objects on the retina.</li>
<li>It acts in much the same way as a biconvex optical glass lens, however, it cannot be moved forward.</li>
<li>Thus, the refractive power of the lens is a function of the curvature of the lens surfaces, as well as the refractive index of the cell mass. </li>
<li>The closely packed, highly ordered array of lens cells is essential for optical quality, and even small defects in lens fiber cell anatomy can cause detectable spherical aberration.</li>

<li>The commonly used temperature scales are Celsius, Fahrenheit, and Kelvin. The temperatures in Celsius, Fahrenheit and Kelvin are represented as ∘C, ∘F and K respectively.</li>

Conversion between Kelvin and Celsius scale:
[K] = [°C] + 273.15
[°C] = [K] − 273.15

<li>The speed at which evaporation takes place is called rate of evaporation. Or you may say it the other way as the amount of vapours formed per unit time is called as the rate of evaporation.</li>
<li>Evaporation is the surface phenomenon in which the particles at the surface gain enough energy to turn into vapour. There is a number of factors that affect the rate of evaporation.</li>
<li>1. Temperature: The rate of evaporation increases in increasing the temperature of the liquid. When the temperature of the liquid is increased by heating it, more particles of the liquid get enough kinetic energy to get into the vapour state. This increases the rate of evaporation.</li>
<li>2. Humidity of Air: When the humidity of air is low then the rate of evaporation is high and water evaporated more readily. The wet clothes dry quickly under the conditions of low humidity of air this is because when the humidity is low, the amount of water vapour present in the air is small.</li>

lcm × hcf = സംഖ്യകളുടെ ഗുണനഫലം

216 × 12 = 108 × X

X = 216 × 12/108

 = 24

selling price of article SP= 448

 profit = 12%

cost price CP= X

SP = P/CP × 100

448 =X × 112/100

X = 448 × 100/112 = 400

ആകെ ജോലി = LCM (10 , 15) = 30

A യുടെ കാര്യക്ഷമത = 30/10 = 3

B യുടെ കാര്യക്ഷമത = 30/15 = 2

A , B ഒരുമിച്ചു ജോലി പൂർത്തിയാക്കാൻ എടുക്കുന്ന സമയം = 30/(3 + 2)

 = 30/5 

= 6 ദിവസം

സാധരണ വേഗതയുടെ 5/4 വേഗതയിൽ സഞ്ചരിച്ചാൽ സാധരണ സമയത്തിന്റെ 4/5 സമയം എടുക്കും 

അതുകൊണ്ട് 5 മിനിറ്റ് നേരത്തെ ലക്ഷ്യ സ്ഥാനത്തു എത്തും 

സാധാരണ സമയം - 4/5(സാധാരണ സമയം ) = 5 മിനിറ്റ്

1/5(സാധാരണ സമയം) = 5 മിനിറ്റ്

സാധാരണ സമയം = 5 × 5 =25മിനിറ്റ്

difference between two consecutive terms is: +4, +8, +16, +32, +64

Clearly, 17 + 16 = 33

35 is the wrong term.
