Answer:
rate of flow of energy(in)=14.3514 KW
Rate of flow of energy(out)=17.8092 KW
change of energy flow=3.4578 KW
Explanation:
The explanation is given in the attachments.
Answer: T= 159.3N
Explanation:
The total Tension on the rope at this point=
Sum of the weight of the ball + the centripetal force on the ball
T= W+ mv^2/r
Where T is tension, W is weight of the ball, m is mass of the ball, r is radius of rotation, v is the velocity of rotation. g= acceleration due to gravity
W= 100N
m= W/g= 100/9.8 = 10.2kg
v= 5m/s
r= 4.3m
Therefore,
T= 100 + 10.2×5^2/4.3
T= 100 + 59.3
T= 159.3N
Option C
VIN (vehicle identification number) are used for vehicle and/or major component identification
<h3><u>
Explanation:</u></h3>
American automobile producers have practiced a vehicle identification number (V.I.N.) to name and recognize motor vehicles. They serve to retain an indication of obstacles, ownership exchanges, and prevent crime. This practice also posted the superimposed major component parts and replacement parts to be noted for each of the classes of vehicles.
Depending on the transport major parts may be marked with the vehicle’s VIN. The component part labels are composed of the alike material as the Federal Safety Certification Labels and are also planned to self destruct if excluded.
Answer:
The claim is valid.
Explanation:
Let assume that heat pump is reversible. The coefficient of performance for the heat pump is:
The claim is valid as real heat pumps have lower coefficients of performance.
