The frequency of the applied voltage is constant
According to kinetic molecular theory temperature is a measure of kinetic energy.There is absolute minimum temperature which occurs when something completely stop moving whereby temperature cannot become lower than this point. The absolute zero which has been extrapolated to exist at about -273 celsius while in kelvin scale is set such that absolute zero is 0 k thus kelvin is better inorder to avoid negative number when calculating.
Answer:
The efficiency of a Stirling engine is 74%
Explanation:
Given:
Temperature of gas when it is cold K
Temperature of gas when it is hot K
The efficiency of a stirling engine,
∴
Therefore, the efficiency of a Stirling engine is 74%
Answer:
Explanation:
1 foot = 12 inches
Sammy is 5 feet tall.
5 feet = ? inches
Multiply the feet value by 12 to find in inches.
5 × 12
= 60
Add 5.3 inches to 60 inches.
60 + 5.3
= 65.3
Answer:
Sodium-vapour lights
Explanation:
Sodium-vapour lights are lights that are a type of gas discharge lamp that uses sodium in a high energy state to produce light,sodium discharge lamps are one of the brightest form of lighting used in motor parks and streets. There are basically two types of sodium-vapour lights, they include the low pressure sodium-vapour lights and the high pressure sodium-vapour lights.
