The 3 blocks north and the 3 blocks south cancel each other, and contribute nothing to the displacement. The total displacement is 3 blocks east.
b. Earth is an electromagnet.
c. A magnet always has a north pol, and may or may not also have a south pole.
d. Permanent magnets can be turned off.
The answer would be B. Earth is an electromagnet.
The Earth is a giant electromagnet. It's electromagnetic field is generated from the currents of electricity coming from molten metal flowing in the outer core of our Earth. The heat from the inner core causes convection and that is how electric current flows within Earth.
Earth us an electromagnet (apex)
Increase, decrease, or remain the same
As we know that
now for the first part we know that
refractive index of vacuum with respect to glass is 2/3
speed of light in glass is
now we will have
Part b)
Now similarly we can say
here refractive index of water with respect to vacuum is 4/3
now we will have
a loss of gravity on earth would stop pulling down the air,water and earth's atmosphere
ther would be a sudden and significant loss of air pressure
the lack of any forceful gravitational pull would turn humans
Without gravity, humans and other objects would become weightless.
