Description : How is the speed of light with the rise in the temperature of the medium? -Do You Know?
Description : The speed of light with the rise in the temperature of the medium : (1) Increases (2) Decreases (3) Remains unaltered (4) Drops suddenly
Last Answer : (3) Remains unaltered Explanation: The speed of light with the rise in the temperature of the medium remains unaltered because speed of light doesn't depend on temperature. It does depend, however ... in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics.
Description : How is the speed of light with the rise in the temperature of the medium?
Last Answer : Remains unaltered

Last Answer : (C) Decreases with decrease in pressure
Description : Pick out the wrong statement. (A) At constant pressure, solubility of a gas in a liquid diminishes with rise in temperature (B) Normally, the gases which are easily liquefied are more soluble ... (D) At constant pressure, solubility of a gas in a liquid increases with rise in temperature
Last Answer : (A) At constant pressure, solubility of a gas in a liquid diminishes with rise in temperature
Description : The heat supplied to the gaS at constant volume is (where m = Mass of gas, cv = Specific heat at constant volume, cp = Specific heat at constant pressure, T2 – T1 = Rise in temperature, and R = Gas constant) A. mR(T2 – T1) B. mcv(T2 – T1) C. mcp(T2 – T1) D. mcp(T2 + T1)
Last Answer : Answer: B
Description : The closed circulatory system is more efficient. Since blood circulates only inside blood vessels it can do it with more pressure reaching farther distances between the organs where hematosis ... exchange independently from the circulation) are generally slower and have a low metabolic rate.
Last Answer : What is the difference between octopuses and mussels regarding their circulatory systems?
Description : Speed of sound in solids is - (1) 10 times that in gas/ 10 (2) 20 times that in gas/ 20 (3) 5 times that in gas/ 5 (4) 15 times that in gas/ 15
Last Answer : (4) 15 times that in gas/ 15 Explanation: Sound travels at 343 m/s in air; it travels at 1,480 m/s in water (4.3 times as fast as in air); and at 5,120 m/s in iron (about 15 times as fast as in air).

Last Answer : (A) 1/√M
Description : The speed of a sound wave in a gas is analogous to the speed of (A) An elementary wave in an open channel (B) Flow in an open channel (C) A disturbance travelling upstream in moving fluid (D) None of these
Last Answer : (A) An elementary wave in an open channel
Description : Speed of sound is maximum in solid, liquid or gas?
Last Answer : solid
Description : What happens to the speed of particles when the temperature heats up?
Last Answer : The speed of particles increase when temperature increase.
Last Answer : At a temperature of centigrade the speed of sound is 332 meters / second.
Description : Speed of sound in air is unaffected by change in : (1) Pressure (2) Humidity (3) Temperature (4) Volume
Last Answer : (1) Pressure Explanation: The speed of sound in air depends on the density of air and the density of air depends on the temperature. The speed of sound is unaffected by pressure. If the atmospheric pressure changes, the speed of sound in air remains constant.
Description : What is the temperature at which the speed of sound in air becomes double its value of 0°C?
Last Answer : 819°C
Last Answer : Pressure
Description : The distance from the Earth to the Sun is about 100 million miles. The speed of light is 186,000 miles per second, and light takes eight minutes to reach the Earth from the Sun. Let's say the ... of light is suddenly doubled to 372,000 miles a second.What time will the Sun rise tomorrow? -Riddles
Last Answer : 6am again. After all, what diffrence does the speed of light make to the answer? It's irrelevant- only the speed of the roation of the Earth matters here.
