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.

Answer:
a) 35 kPa
d) 140 N
c) 1) Increasing the brake fluid pressure
2) Increasing the slave piston surface area.
Explanation:
The parameters given are;
a) Force applied to the master cylinder piston = 28 N
Cross sectional area of the master cylinder piston = 8 cm² = 8 × 10⁻⁴ m²
The pressure P on the brake fluid is given by the formula for pressure as follows;
The pressure on the brake fluid, P, produced by the master cylinder piston = 35,000 Pa = 35 kPa
b) Given that the area of the slave piston = 40 cm² = 0.004 m², we have from the formula for pressure, P;
Therefore;
Applied force on the slave piston = 4 × 10⁻³ m² × 35,000 N/m² = 140 N
c) The force, F produced by the slave cylinder piston is given by the relation;
F = Pressure × Area
Therefore, the two ways of increasing the force produced by the slave cylinder piston is as follows;
1) Increasing the pressure in the brake fluid by increasing the force exerted by the master cylinder piston
2) Increasing the surface area of the slave piston.
