Which of the following features are found at an oceanic-continental convergent plate boundary?choose all that apply: 1-island ar
c2-continental arc3-mid-ocean ridge4-mountains5-trench
2 answers:
Answer: 1. Island Arc, 4. Mountains, 5. Trench
Explanation:
A thick less dense continental plate and a thin, dense oceanic plates are two tectonic plates that comes together to create an oceanic-continental plate boundary. The process is called subduction.
The convergent boundary forms strong earthquakes, volcanic mountains or volcanic arc mountain ridges on the surface when the sinking oceanic plates melts.
Other features formed along tectonic plate boundary include: OCEAN TRENCHES, ISLAND ARC, SUBMARINE MOUNTAIN RANGES, and some others.
Therefore, only numbers 1, 4 and 5 are correct.

let us consider that the two charges are of opposite nature .hence they will constitute a dipole .the separation distance is given as d and magnitude of each charges is q.
the mathematical formula for potential is
for positive charges the potential is positive and is negative for negative charges.
the formula for electric field is given as-
for positive charges,the line filed is away from it and for negative charges the filed is towards it.
we know that on equitorial line the potential is zero.hence all the points situated on the line passing through centre of the dipole and perpendicular to the dipole length is zero.
here the net electric field due to the dipole can not be zero between the two charges,but we can find the points situated on the axial line but outside of charges where the electric field is zero.
now let the two charges of same nature.let these are positively charged.
here we can not find a point between two charges and on the line joining two charges where the potential is zero.
but at the mid point of the line joining two charges the filed is zero.
