Impulse=force x time
force=mass x acceleration due to gravity
force=
impulse =3000 x 2.5= ( sorry i don't have a calculator right now so you must calculate this yourself)
I converted from kg to g because it is the standard.
Hope this helps you.
Answer:
A. El volumen
B. La densidad.
Explanation:
A derived quantity is defined as one that has to be calculated by using two or more other measurements.
Volume is a derived quantity because it requires one to use different measurements to determine it. For instance, in the case of a cube, the length, width and height of the cube are all needed to calculate volume.
Density is also a derived quantity because it needs both volume and mass for it to be calculated.
6 months with no sunrise and the other 6 without a sunset, at some places on Earth, are the result of the orientation of Earth's axis.
The way these supersaturated solutions are made is: A. The water would need to be heated to a higher temperature, which would give molecules and ions more kinetic energy, increasing solubility.
Solubility is simply a measure of how readily a substance is able to dissolve in a solvent to form a solution. Thus, a substance is soluble when it dissolves completely in a solvent and it is considered to be insoluble when it does not dissolve in a solvent or if it only dissolves partially.
A supersaturated solution can be defined as a solution that contains more solute than the equilibrium amount.
Generally, supersaturated solutions of solids in water are typically used for the creation of crystals because they are able to hold more of the solute than they would at room temperature.
In order to create these supersaturated solutions, the water should be heated to a higher temperature, so that the water molecules and ions can gain more kinetic energy and thereby increasing solubility.
In conclusion, heating the water to a higher temperature causes the water molecules and ions to gain more kinetic energy and thereby increasing solubility..

Answer:
a. Mass flow rate through the boiler = 5.462lbm/s
b. Power produced by the turbine = 2525.8kW
c. The rate of heat supply in the boiler = 6901.42Btu/s
d. Thermal efficiency of the cycle = 34.3%
Explanation:
In order to provide a solution, we must assume that ;
- The system is operating at a steady condition
- Kinetic and potential energy changes are negligible
Now from steam tables, we calculate specific volume 
and enthalpy 
as,
( 
at 
)
( 
at )
( at 
& 
)
( 
& 
when pressure is 2psia)
Therefore,
To calculate the mass flow rate of steam in the cycle, we use the formula
where 
The power output and the rate of heat addition are calculated thus,
The thermal efficiency of the cycle can be found thus;
= 34.3%
