Answer:
unit =1.83
Explanation:
The cooling load is due to people, lights, and heat transfer through the walls and the windows so. The total cooling load of the room is determined from
(Equation 1) Q cooling = Q lights + Q people + Q heat gain
there fore
Q cooling = 10 x 100 W = 1 KW
Q people = 40 x 360 KJ/h = 4 KW
Q heat gain = 15.000 kJ/h = 4.17 KW
we replace the values in Equation 1
Q cooling = Q lights + Q people + Q heat gain
Q cooling = 1 + 4 +4.17
Q cooling = 9.17 KW
Thus the number of air — conditioning units required is
9.17 KW /5 KW unit =1.83
The relationship between force (F), mass (m) and acceleration (a) is described in the equation F = ma. This equation means that a new force acting on a body will change velocity, and conversely, a change in velocity will generate a force
Answer:
Correct answer is (c) a global "repaving" that erased essentially all the surface features that had existed earlier
Explanation:
Venus underwent cyclic process which erased the proved of other craters about billion years back. This is termed Venus global resurfacing event.
