Sorry if I’m wrong and hope this helps !
Answer:
The required mechanical work is required to reduce each day by 1.05×10^8 Joules.
Explanation:
Coefficient of Performance (COP) = Q/W
Q is thermal energy absorbed by the air conditioner
W is mechanical work done
Q = 3.9×10^8 J
COP of old air conditioner = 2.3
W = Q/COP = 3.9×10^8/2.3 = 1.70×10^8 J
COP of new air conditioner = 6
W = Q/COP = 3.9×10^8/6 = 6.5×10^7 J
Reduction in mechanical work = (1.7×10^8) - (6.5×10^7) = 1.05×10^8 J
Answer:
In return mode, the system assists steering return after completing a turn. Information from the steering position sensor prevents the system from overshooting the center position. In dampener mode, the system acts like a hydraulic dampener to prevent kick back and bump steer.
Answer:1.458 Btu
Explanation:
Given
radius of canister
Height of canister
Initial pressure
Initia ltemprature
Final pressure
as canister is rigid therefore change in volume is zero
therefore
=
=
volume of canister=
=
volume of canister=12872,038.8 
now calculating mass of air
PV=mRT
substituting values
m=21.0192 gm
Therefore heat transferred =
=
=1539.052J=1.458Btu
