The pressure at the bottom of a jug filled with water does NOT depend on the
1 answer:
Answer:
D) surface area of the water
Explanation:
The pressure at the bottom of a column of fluid is given by Stevino's law:
where
p is the pressure at the bottom of the column
is the density
g is the acceleration due to gravity
h is the depth of the liquid
So, we see that the pressure at the bottom of a jug filled with water depends on all these quantities:
A) depth of the liquid
B) acceleration due to gravity
C) density of water
While it does not depend on:
D) surface area of the water

Answer:
The amount of matter in an object is its mass
An action that has the ability to change an object's state of motion is a force
The rate at which velocity changes over time is acceleration
Explanation:
- Mass is a scalar quantity that gives a measure of the amount of matter contained in an object/substance. The SI unit of the mass is the kilogram (kg). Mass is an intrinsec property of an object, that means that it does not change when the object is moved in another location.
- A force is a vector quantity, that indicates an action exerted on an object that changes the state of motion of the object. It is measured in Newtons (N). According to Newton's second law, the acceleration of an object is equal to the net force exerted on the object divided by its mass:
- Acceleration is a vector quantity, which is equal to the ratio between the change in velocity of an object and the time interval taken for that change to occur. It is measured in meters per second squared (). Mathematically, it is defined as
