Pressure = height x density x gravity = 2 x 1000 x 9.8 = 19600 Pascal ( N / m^2 )
Answer:
B - False
Explanation: a dispersed formation means spreading out, more like an attacking or advancing position. This doesn't depict a defensive measure.
Answer:
Electric and magnetic fields:
Maxwell's equations tell us that
a changing magnetic field creates a changing electric field and
a changing electric field creates a changing magnetic field
Answer:
Weight measurement at poles will be slightly more than at equator.
Explanation:
Firstly earth bulges at equator. This makes the body far from earth center at equator than poles. Secondly, the surface centrifugal forces of earth due to rotation also plays vital role in disturbing the gravity value. The centrifugal forces cancel the effect of gravity more at equator than at poles.These factors combine to create difference of about 0.5% in gravity values at pole and equator.
gravity at pole=9.832 m/s^2
gravity at equator=9.780 m/s^2
