Answer:
the maximum height h to which the the water steam could rise is 40.65m
Explanation:
Given;
= 20m,
= 2atm ≈ 20265 N/m
Density of water ρ = 1000 kg/
Note: we take point 1 at the free surface of the water in the tank and point 2 at the top of the water trajectory. we also take reference level at the bottom of the tank.
fluid velocity at the free surface of tank is very low (
≅ 0) and at the top of the water trajectory 
= 0
Step 1: Applying Bernoulli equation between poin 1 and point 2
/ρg + 
/2g + = 
/ρg + 
/2g + 
/ρg + = 
/ρg +
= ( - )/ρg +
Substituting values into we have,
= 
Answer:
Water surface tension
Explanation:
The water around the paperclip forms a kind of elastic surface, deforming, in which the clip can stay afloat.
This is because the molecules that are on the surface of the water, already in contact with the air, try to cling to those that are next to them and those that are immediately below.
If we added even if it were just a drop of soap in the water, the clip would go to the bottom, because the soap has the ability to decrease the surface tension of the water.

Biometric sensors are used to collect measurable biological characteristics from a human being, which can then be used in conjunction with biometric recognition algorithms to perform automated person identification.
Answer:
1. General purpose file server.
2. Virtual Desktop Infrastructure Server.
3. Virtualized Backup Server.
All except : Database server
Explanation:
As a simple definition, we can tell, data deduplication is an elimination of redundant data in data set and storing only one copy of the same data. It is done by identifying double byte patterns through data analysis, removing double data and replacing it with reference pointed to stored, single piece of data.
