Answer:
it will most likely turn off?
2.496 HZ is the resistance change the resonant frequency.
Given, Supply frequency, f = 60 12
number of poles, P = 4
Full load speed, Ne= 1725 rpm
Synchronous speed; No= 1201= 120X60 = 1800 rpm
P
4
We know the formula for Full load-speed
Ne = N's (1 - Sf)
where se = full load rotor ship
Ne = 1 - SP
SQ = 1- Ne = 1- 1725 = 0.0416 DY 4-16%
1800
SQ= 4. 16 % or 0.0416
Frequency of rotor, fy= Sgif = (0.0416) ( 60 ) = 2.496 Hz
fr = 2.496 HZ

Answer:
15.8m/s
Explanation:
This problem can be solved by taking into account the conservation of the momentum. In this case the momentum of the astronaut and the bag of tools must equal the momentum of the astronaut and the bag of tool after the astronaut throws the bag.
Hence, we have

where ma and va are the mass and velocity of the astronaut, mb and vb are the mass and velocity of the bag, after the astronaut throw the bag. The velocity v is the velocity where the astronaut has the bag of tool
By taking into account that the velocity of the astronaut must be zero to keep him near of the space station, we have that vb = 0.
Thus

<span>A) cools down, slows down. When you put water in the freezer, it cools down and then the particles reduce their speed until they eventually form a solid by freezing.</span>
