Answer:
launch- The first stage is ignited at launch and burns through the powered ascent until its propellants are exhausted. The first stage engine is then extinguished, the second stage separates from the first stage, and the second stage engine is ignited. The payload is carried atop the second stage into orbit

coasting flight-
When the rocket runs out of fuel, it enters a coasting flight. The vehicle slows down under the action of the weight and drag since there is no longer any thrust present. The rocket eventually reaches some maximum altitude which you can measure using some simple length and angle measurements and trigonometry.
ejection charge-At the end of the delay charge, an ejection charge is ignited which pressurizes the body tube, blows the nose cap off, and deploys the parachute. The rocket then begins a slow descent under parachute to a recovery. The forces at work here are the weight of the vehicle and the drag of the parachute.
slow decent- slow downs (i guess)
recovery-A recovery period is typically characterized by abnormally high levels of growth in real gross domestic product, employment, corporate profits, and other indicators. This is a turning point from contraction to expansion and often results in an increase in consumer confidence

I hope it helped if it did pls make me brainliest
Answer:
a) 1 m^3/Kg
b) 504 kJ
c) 514 kJ
Explanation:
<u>Given </u>
-The mass of C_o2 = 1 kg
-The volume of the tank V_tank = 1 m^3
-The added energy E = 14 W
-The time of adding energy t = 10 s
-The increase in specific internal energy Δu = +10 kJ/kg
-The change in kinetic energy ΔKE = 0 and The change in potential energy
ΔPE =0
<u>Required </u>
(a)Specific volume at the final state v_2
(b)The energy transferred by the work W in kJ.
(c)The energy transferred by the heat transfer W in kJ and the direction of
the heat transfer.
Assumption
-Quasi-equilibrium process.
<u>Solution</u>
(a) The volume and the mass doesn't change then, the specific volume is constant.
v= V_tank/m ---> 1/1= 1 m^3/Kg
(b) The added work is defined by.
W =E * t ---> 14 x 10 x 3600 x 10^-3 = 504 kJ
(c) From the first law of thermodynamics.
Q - W = m * Δu
Q = (m * Δu) + W--> (1 x 10) + 504 = 514 kJ
The heat have (+) sign the n it is added to the system.
Tempo decides the speed at which the music is played.
<u>Explanation:</u>
The Tempo of a bit of music decides the speed at which it is played, and is estimated in beats per minute (BPM). The 'beat' is dictated when mark of the piece, so 100 BPM in 4/4 compares to 100 quarter notes in a single moment.
A quick tempo, prestissimo, has somewhere in the range of 200 and 208 beats for each moment, presto has 168 to 200 beats for every moment, allegro has somewhere in the range of 120 and 168 beats for every moment, moderato has 108 to 120 beats for every moment, moderately slow and even has 76 to 108, adagio has 66 to 76, larghetto has 60 to 66, and largo, the slowest rhythm, has 40 to 60.
