While watching some tv you see a circus show in which a woman drives a motorcycle around the inside of a vertical ring. you dete
Mila [183]

Since the biker is moving at constant speed

so we will have

v = \frac{distance}{time}

here we know that

distance = 2\pi R

time = 4 second

now we have

v = \frac{2\pi R}{4} = \frac{\pi R}{2}

now at the top point it feels free fall

so it is

mg = \frac{mv^2}{R}

v^2 = Rg

(\frac{\pi R}{2})^2 = Rg

R = \frac{4g}{\pi^2}

so height of the bike at the top is same as diameter

h = 2R

h = \frac{8g}{\pi^2} = 7.95 meter

Yes it will hurt on falling from this height

The Andromeda galaxy is the closest major galaxy to our own. Andromeda shows a distinct blue-shift of light when we analyze it.
saul85 [17]
At the present time, the only way we know of that light can get shifted
toward the blue end of the spectrum is the Doppler effect ... wavelengths
appear shorter than they should be when the source is moving toward us. 

IF that's true in the case of the Andromeda galaxy, it means the galaxy is
moving toward us.

We use the same reasoning to conclude that all the galaxies whose light is red-shifted are moving away from us.  That includes the vast majority of all galaxies that we can see, and it strongly supports the theory of the big bang
and the expanding universe.

If somebody ever comes along and discovers a DIFFERENT way that light
can get shifted to new, longer or shorter wavelengths, then pretty much all
of modern Cosmology will be out the window.  There's a lot riding on the
Doppler effect !

Which is true of magnetic field lines but not electric field lines?
marusya05 [52]

D

The closer the field lines, the stronger the field, whereas for electric field, the higher the electric flux passing through, the stronger the electric field.

Explanation:

Another difference between the two is that magnetic fields formed closed loops around the magnetic while electric fields do not. Electric fields are measured in two dimensional while magnetic fields in 3 dimensional. The electric field line can do work while magnetic fields can not (because particles in magnetic field remain constant even though the charge may change direction).
