Answer:
A. 6.36 lbm/s
b. 
Explanation:
a. Given the following information;
#Compressor inlet:
Air pressure,
#Compressor outlet:
#Cooling rate,
# From table A-1E
Gas constant of air 
Specific enthalpy at 
Using the mass balance:
Hence, the mass flow rate of the air is 6.36lbm/s
b The specific enthalpy at the exit is defined as the energy balance on the system:
Hence, the temperature at the compressor exit
During a 30-10 million year period starting at about 4.5 billion years ago, bits and pieces of metal-rich particles, rocks, and ices accumulated to form the earth.
<h3>What is the Earth?</h3>
This is referred to as a type of planet which is habitable for different types of life forms. It is also the third planet from the sun and a majority of it contains water such as oceans etc.
Earth was formed billions of years ago through the bits and pieces of metal-rich particles, rocks, and ices which was in a 30-10 million year period which therefore makes it the correct choice.

Answer:
It is called a mixture.
Explanation:
A mixture is a physical combination of 2 or more substances that are blended together without forming a new substance.
Because then it could mess up the machine with to much energy
Answer:
the velocity is zero, the acceleration is directed downward, and the force of gravity acting on the ball is directed downward
Explanation:
Is this exercise in kinematics
v = v₀ - g t
where g is the acceleration of the ball, which is created by the attraction of the ball to the Earth.
At the highest point
velocity must be zero.
The acceleration depends on the Earth therefore it is constant at this point and with a downward direction.
The force of the earth on the ball is towards the center of the Earth, that is, down
all other alternatives are wrong
