Answer:
exit temperature 285 K
Explanation:
given data
temperature T1 = 270 K
velocity = 180 m/s
exit velocity = 48.4 m/s
solution
we know here diffuser is insulated so here heat energy is negleted
so we write here energy balance equation that is
0 = m (h1-h2) + m ×
.....................1
so it will be
.....................2
put here value by using ideal gas table
and here for temperature 270K
h1 = 270.11 kJ/kg
solve it we get
h2 = 285.14 kJ/kg
so by the ideal gas table we get
T2 = 285 K

The correct answer is A; True.
Further Explanation:
This is a correct phrase that is important to learn when owning any type of vehicle. When a car battery is dead, it can usually be jump started by using another cars battery or a portable battery charger. It is extremely important to put the positive battery cable on the positive battery post. Then the negative cable will be placed on the negative car battery post and the negative ground wire can be anywhere on the car except on the battery.
The car needs to be connected properly for a few minutes before trying to start the car. This helps the car battery to get enough "juice" to start. If the battery cables are placed wrong this can cause sparks to come out of the cables/battery and cause bodily harm.

The relationship between resistance and the area of the cross section of a wire is inversely proportional . When resistance is increased in a circuit , for example by adding more electrical components , the current decreases as a result.
