Answer:
Mid-Ocean Ridges
Explanation:
The mid-ocean ridges is an underwater mountain system formed by diverging oceanic plates.
- This mid - ocean ridge is one of the prominent land mass on the earth surface.
- At a diverging center, two tectonic plates are pulling apart from one another.
- This creates a space which allows for magma to rise up.
- The magma then crystallize to form an extensive ridge network known as the mid - oceanic ridge.
- The continental expression of the ridge can only be found in Iceland
Answer:
Photoelectric Effect
Explanation:
Photoelectric Effect is a phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation.
1/f= 1/di+1/do
1/f=1/90m+1/40m
1/f ≈27.7m
Galaxies are much further apart than stars. This is the reason why they are less likely to collide and the likelihood of galactic collision is much smaller than the likelihood of stellar collision. Example for galaxy collision is the collision of the Milky Way galaxy with Andromeda. It is estimated that the collision will be <span>in about 4.5 billion years. </span>
Answer:
i = 0.5 A
Explanation:
As we know that magnetic flux is given as
here we know that
N = number of turns
B = magnetic field
A = area of the loop
now we know that rate of change in magnetic flux will induce EMF in the coil
so we have
now plug in all values to find induced EMF
now by ohm's law we have
