A boat is floating in a small pond. the boat then sinks so that it is completely submerged. what happens to the level of the pond?
It increases!
The wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats.
Answer:
41.053 A
Explanation:
given,
three phase kVA = 25-kVA
voltage = 440 Volt
current = ?
To determine three phase kVA when volts and amperes are know
three phase kVA = 1.73 x V x I
![I = \dfrac{three\ phase\ kVA}{1.73 \times V}](https://tex.z-dn.net/?f=I%20%3D%20%5Cdfrac%7Bthree%5C%20phase%5C%20kVA%7D%7B1.73%20%5Ctimes%20V%7D)
![I = \dfrac{25000}{1.73 \times 440}](https://tex.z-dn.net/?f=I%20%3D%20%5Cdfrac%7B25000%7D%7B1.73%20%5Ctimes%20440%7D)
I = 32.84 A
the maximum overcurrent protection value is equal to
= 125 % of I
= 1.25 x 32.84
= 41.053 A
Answer:
The number of molecules displaced in a vibration makes the amplitude of a sound.
Answer: The lower areas of the Atmosphere have a high temperature through the heats from the ground.
Explanation: High temperature experienced on the Earth surface is majorly caused by heats from the ground ( Earth crust).As a person ascend up to the Toposphere the temperature continues to reduce because because the heat from the ground is reduced as the heights increased.
It has been proven that as a person ascends into the Toposphere the amount of air and pressure reduces this will eventually lead to expansion of the gas particles which will then reduce the temperature.
