Magnetic field lines always forms closed loop in such a way that it originates from North pole and then terminates back into the South pole
Inside the magnet we will draw the field lines from south pole to north pole
So it is not possible that magnetic field lines originates from north pole and again terminates at the same pole
So this is
FALSE
Answer:
h=20.38 m
Explanation:
Given that
Initial speed of object u = 20 m/s
Acceleration 
We know that
Here acceleration and velocity is in opposite direction so the object will come rest after reaching at distance h.When body will reach at its highest position then velocity will become zero(v=0).
Now by putting the values
h=20.38 m

Answer:
Explanation:
Velocity of a wave is describe as
velocity =Frequency × Wavelength
Mathematically
v = fλ
Hence, Frequency, F = v / λ
Wavelength λ = v/f
So, if the frequency is kept constant, wavelength of the wave becomes directly proportional to velocity of the wave.
And this implies that, as the speed double, the wavelength is double.
