The cycle used by the engine is composed of three processes: a process at constant pressure between point 1 and 2, a process at
aev [14]

Answer:

Isobaric process between points 1 and 2 while isochoric process between 2 and 3.

Explanation:

A themodynamic equilibrium system which changes from initial state to the final state by a process is known as thermodynamic processes. There are many different kinds of thermodynamic process which depends upon the thermodynamic quantities such as pressure, volume, temperature, entropy etc. The most common thermodynamic processes are isobaric, isothermal, isochoric and adiabatic.

When the temperature of the system remains same during the thermodynamic process, the process is known as isothermal.

When the heat of the system remains same during the thermodynamic process, the process is known as adiabatic.

When the volume of the system remains same during the thermodynamic process, the process is known as isochoric.

When the pressure of the system remains same during the thermodynamic process, the process is known as isobaric.

According to the question, between points 1 and 2 pressure remains constant, hence the process is isobaric.

According to the question, between points 2 and 3 volume remains constant, hence the process is isochoric.

*Please help this is my final* If the car has a mass of 700 kg, how many newtons of forxe were used to accelerate it 30m/s/s
Vaselesa [24]

Answer:

21,000 N

Explanation:

You would use the formula F=ma

So you would do substitution...

F=700 kg(30 m/s/s)

F=21,000 N

In higher pressure environments, less gas can be dissolved in a solvent. True or False?
densk [106]

Nope.  Just the opposite.

That's why, when you open a new bottle of soda and
let the pressure inside come down to atmospheric
pressure, some of the sparkly gas comes out of solution
and goes "hisss" out of the bottle.  (If you open the bottle
too fast, then some of the soda comes out with the gas.)

Momentum=mass*velocity

Mass=55kg

Velocity=?

Momentum=220kg.m/s

P=mv

v=p/m

v=220/30

v=7.33m/s
