Explanation:

a law stating that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature.

It will decrease because increasing an object's temperature decreases its thermal energy. It will increase because increasing an object's temperature increases its thermal energy. It won't change because an object's thermal energy does not depend on its temperature....

A ground water tank has its height 2m. Calculate the pressure at its bottom when it is completely filled with water.​
Law Incorporation [45]

The pressure at the bottom : 19600 N/m²

<h3>Further explanation</h3>

Given

A ground water tank has its height 2m

Required

The pressure at its bottom

Solution

Hydrostatic pressure is the pressure caused by the weight of a liquid.  

The weight of a liquid is affected by the force of gravity.  

The hydrostatic pressure of a liquid can be formulated:  

\large{\boxed{\bold {P_h ~ = ~ \rho.g.h}}

Ph = hydrostatic pressure (N / m², Pa)  

ρ = density of liquid (kg / m³)  

g = acceleration due to gravity (m / s²)  

h = height / depth of liquid surface (m)  

ρ = density of water (kg / m³) = 1000

g = acceleration due to gravity = 9.8 m/ sec²

The pressure

\tt P=1000\times 9.8\times 2=19600~N/m^2

Which feature forms at convergent
geniusboy [140]

B trench

Explanation:

The feature found at most convergent margins is a trench.

A trench is a large depression that typifies most convergent margins.

  • Oceanic trenches are natural topographic depressions found on the sea floor.
  • These depressions forms where two plate boundaries converges.
  • The denser one slides beneath the less dense one into the asthenosphere below.
  • This is called a subduction zone.
  • The margin between the two plates that are depression is a trench.
