Answer: Kinetic energy increases and potential energy decreases when the velocity of an object increases
Explanation: probably that one
Answer:
the pilot should head the plane 
towarrds south- west
Solution:
The airspeed of the airplane, v = 280 km/h
The velocity of the wind, v' = 52 km/h South-west
Angle, 
Now, measured angle in the clockwise direction from North:
Now,
south- west
On half life is 5370 years; 6 half lives have passed. You just multiply,
5370*6 = 32,220 years
Answer:
727.67 km
Explanation:
Sine they have Same distance D
distance = speed * time
D = 5.08t
D = 8.3312(t+55.9)
so
5.08t = 8.3312(t+55.9) t in
3.2512t = 465.71
t = 143.2s
Subtitute t
D=5.08 t
= 5.08 × 143.2
= 727.67km
