We need to find the equations of the sides of triangle whose vertices are (-2,0) , (2,4) and (4,1) Now to find the equation of side AB,  Let A(-2,0) = (x1 , y1)  and B = (2,4) =(x2 , y2) So equation of AB is y - y1 = .....

Genes are located on rodlike structures called chromosomes that are found in the nucleus of every cell in the body. Each gene occupies a specific position on a chromosome. Because genes provide instructions for making proteins, and proteins .....

The number of chromosomes in each generation are maintained due to meiosis. The meiosis is a kind of reductive division. When gametes are formed by meiosis, the number of chromosomes are halved. Hence each gamete will have only one pair of .....

Definitely, Kathmandu is colder than Terai. The reasons behind this are as follows:  - There is an altitude difference between Kathmandu and Terai. So, as the altitude increases the temperature decreases. Due to which, Kathmandu is colder .....

Our Earth receives all its heat mostly from the Sun. Since Earth is spherical in shape, sun rays fall on different places on Earth at different angles. This is the reason why every part of our planet is not equally hot. On the equator, the sun .....

Electromagnetic waves are made up of photons (dual nature consideration). Photons do not interact with other photons. For example,  the light from this screen is not just going in your eyes, but everywhere else around the room. But .....

Spectrum is produced by the deviation of a different colour by the mean of refraction and spectrum takes place. When white light travels from air into the hollow prism (contains air) so there is no change of medium, therefore no refraction and .....

The penetrating power is determined by the peak energy (kVp) of the voltage placed across the X-ray tube. The higher the energy the greater the penetrating .....

 Melanocytes are special skin cells that produce melanin (skin pigment) when they are exposed to ultraviolet light in sunlight.   The pigment absorbs UV radiation in .....

This is because Violet has the least velocity in the spectrum and therefore undergoes maximum refraction.  Violet light has a shorter wavelength, and short wavelengths travel more slowly through a .....

If the diamond is placed in water, the critical angle is increased. This is because it depends on the ration of the indices of refraction across the boundary. So whilst in the air, a diamond has a ratio across the diamond/air boundary of .....

That the Sun appears larger when it is on the horizon is just an optical illusion. The brain thinks that objects on the horizon should be farther away than objects overhead; since the Sun is the same apparent size in both places, the brain .....
