Answer:
The total system active power P = P_1 + P_2 + P_3 = 34.91 KW
Explanation:
Load 1: Active power P_1 = 20 HP = 14.91kW;
Reactive power 

Load 2: Active power P_2 = 20 kW;
Reactive power Q2 = 0 since the load is purely resistive.
Load 3: Active power
= 0 due to purely capacitiveload
Reactive power
= -20 Var
a) since all three loads are connected in parallel therefore
The total system active power P = P_1 + P_2 + P_3 = 34.91 KW
Total system reactive power Q = Q_1 + Q_2 + Q_3 = 11.18 + 0 -20 = -8.82 kVar
Since Q = 0, the power factor is unity.
Supply current per phase is given by


Answer:
The instantaneous axis of rotation=
x = 0 ; z = 8.4 ft
Explanation:
Given:
Speed of helicopter, Vo= 120 mi/h, converting to ft/sec, we have:

= 176 ft/s
Angular velociyy, w = 220 rpm, converting to rad/sec, we have: 
The helicopter moves horizontally in the x direction at a speed of 120 mi/h, this means that the helicopter moves in the positive x direction at 120mi/h
To find the instantaneous axis of rotation of the main blades, we have:
Where Vc = 20.95 rad/s
Vo = 176 ft/s

= 8.4 ft
Therefore the axis of rotation=
x = 0 ; z = 8.4 ft

Answer:
Civil Engineering.
Explanation:
Civil Engineering is a field of engineering study that deals with professional practising in designing and developing infrastructures such as transport system and networks, buildings, etc.
<u>Civil engineering is regarded as the second--oldest form of engineering studies in the field of engineering.</u>
<u>A person who studies civil engineering is able to design and develop major projects in transportations system such as road construction, bridges, airports, tunnels, etc.</u>
So, Danny, who is interested in studying transporation networks and system should opt for studying civil engineering.
Answer:
C is the correct answer coz the others don't make sense
