Q803. What is the lower fixed point of fahrenheit scale?
Q803. What is the lower fixed point of fahrenheit scale?
Answer: (B) 32°F
Answer: (B) 32°F
Answer: (B) 32°F
The lower fixed point in Fahrenheit scale is 32 degree and upper fixed point in Fahrenheit scale is 212 degree. The difference between the two is 180, hence number of division is 180.

Q804. What is the normal temperature of human body?
Q804. What is the normal temperature of human body?
Answer: (A) 37°C
Answer: (A) 37°C
Answer: (A) 37°C
Normal body temperature is considered to be 37°C (98.6°F); however, a wide variation is seen. Among normal individuals, mean daily temperature can differ by 0.5°C (0.9°F), and daily variations can be as much as 0.25 to 0.5°C.

Q806. What is the audible range of frequencies for normal human ears?
Q806. What is the audible range of frequencies for normal human ears?
Answer: (B) 20 Hz to 20,000 Hz
Answer: (B) 20 Hz to 20,000 Hz
Answer: (B) 20 Hz to 20,000 Hz
The audible range of an average human ear lies between 20 Hz to 20,000 Hz. Humans cannot hear sounds having frequency less than 20 Hz and greater than 20,000 Hz.

Q807. Why the sky appears blue?
Q807. Why the sky appears blue?
Answer: (C) Dispersion of light
Answer: (C) Dispersion of light
Answer: (C) Dispersion of light
Blue colour of the sky is due to dispersion or scattering of light. The two most common types of matter present in the atmosphere are gaseous nitrogen and oxygen. These particles are most effective in scattering the higher frequency and shorter wavelength portions of the visible light spectrum.

Q808. Beyond what distance a normal eye can see objects clearly?
Q808. Beyond what distance a normal eye can see objects clearly?
Answer: (C) 25 cm
Answer: (C) 25 cm
Answer: (C) 25 cm
For a clear vision, the image must be on the retina. The image distance is therefore fixed for clear vision and it equals the distance of retina from eye lens. It is about 25 cm for a grown up person. A person can theoretically have clear vision of an object situated at any large distance from the eye.

Q809. The speed of light is maximum in
Q809. The speed of light is maximum in
Answer: (D) Vaccum
Answer: (D) Vaccum
Answer: (D) Vaccum
The speed of light is maximum in a vacuum. Vacuum is the least dense medium with no obstruction to the path of light. Its refractive index is equal to unity, hence, the speed of light is maximum in a vacuum.
