Answer:
effeciency n = = 49%
Explanation:
given data:
mass of aircraft 3250 kg
power P = 1500 hp = 1118549.81 watt
time = 12.5 min
h = 10 km = 10,000 m
v =85 km/h = 236.11 m/s
kinetic energy
kinetic energy 
gravitational energy 
total energy 
effeciency n = = 49%
Answer:
No, some energy will be dissipated energy due to work of air resistance.
1 is A
2 is D
3 is D
4 is B
As both chlorine and sulfur throw their electrons such that they achieve their stable electrons to be the so called " modal atom " Therefore chlorine have to throw 1 electron to form 8 and sulfur have to throw 2 to form 8 . Therefore if they throw it will be negative while if they add it will be positive .
* Remember ( All Atmos have electronic figuration of most 2,8 or 2,8,8,8 )
