Answer:
Magnitude of vector A = 0.904
Explanation:
Vector A , which is directed along an x axis, that is
Vector B , which has a magnitude of 5.5 m
The sum is a third vector that is directed along the y axis, with a magnitude that is 6.0 times that of vector A 
Comparing we will get
Substituting in 
So we have
Magnitude of vector A = 0.904
B, do earthworms prefer bright light or darkness!
Auroras are frequently seen : B. After solar flares
The Aurora is created by an ongoing influx of particles into the Earth's existing magnetic field,
This particles originated from the Sun as part of Solar wind

I have my ways ;)
Answer:
K.E = 0.0075 J
Explanation:
Given data:
Mass of the ball = 1.5 kg
radius, r = 50 cm = 0.5 m
Angular speed, ω = 12 rev/min = (12/60) rev/sec = 0.2 rev/sec
Now,
the kinetic energy is given as:
K.E = 
where,
I is the moment of inertia = mr²
on substituting the values, we get
or
K.E = 0.0075 J
