Answer:
S=2.693m
Explanation:
Let point 
be the origin of the room and the fly is crawling at point 
as shown in the attached photo:
#Distance of the fly from the corner of the room is defined as:
#Substitute the coordinate values in the above equation:
Hence, the distance of the fly from the corner of the room is 2.693m
Answer:
The Sun’s magnetic field, solar winds and the Earth's magnetic tail are responsible for making the aurora lights in the north and south poles look different, say international scientists. Researching the interactions of these phenomena have debunked previous theories around why the lights can have different shapes and can occur in different locations. This research also helps scientists to better understand the interactions between the sun and earth, which could help with predicting space weather.

Is the energy contained in the particles of a medium
Answer:
(i) -556 rad/s²
(ii) 17900 revolutions
(iii) 11250 meters
(iv) -55.6 m/s²
(v) 18 seconds
Explanation:
(i) Angular acceleration is change in angular velocity over time.
α = (ω − ω₀) / t
α = (10000 − 15000) / 9
α ≈ -556 rad/s²
(ii) Constant acceleration equation:
θ = θ₀ + ω₀ t + ½ αt²
θ = 0 + (15000) (9) + ½ (-556) (9)²
θ = 112500 radians
θ ≈ 17900 revolutions
(iii) Linear displacement equals radius times angular displacement:
s = rθ
s = (0.100 m) (112500 radians)
s = 11250 meters
(iv) Linear acceleration equals radius times angular acceleration:
a = rα
a = (0.100 m) (-556 rad/s²)
a = -55.6 m/s²
(v) Angular acceleration is change in angular velocity over time.
α = (ω − ω₀) / t
-556 = (0 − 15000) / t
t = 27
t − 9 = 18 seconds
