A. The pressure is greater at the bottom of the container.

Answer from: ninaaforever

Answer;

A. The pressure is greater at the bottom of the container

Explanation;Pressure is the force acting on a given area. Pressure in fluids is given by the product of density, depth and the gravitational acceleration.Therefore, an increase in the depth of a given fluid, results to a corresponding increase in pressure, and thus the pressure in liquids increases with depths.Hence, in this case the pressure will be higher a the bottom of the container. Additionally, apart from the depth being higher at the bottom of the container resulting to high pressure, the pressure at the bottom of the container is higher because it is the sum of atmospheric pressure and the pressure due to liquid column.

Answer from: Quest

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

$f\alpha \frac{dp}{dt}$

⇒ $f= k \frac{dp}{dt}$

here k is the proportionality constant whose value is 1.

$f=\frac{dp}{dt}$

$f= \frac{d[mv]}{dt}$

$f= m\frac{dv}{dt} +v\frac{dm}{dt}$

$f=ma+v\frac{dm}{dt}$ [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
