The unit of land area in countries that use the SI system is the hectare, defined as 10,000 m^2. In the US, land area is in acres, an acre is defined as 43,560 ft. You just bought of land with dimensions 2.00 km by 4.00 km. What is the area of your land purchased in hectares and acres?​

force tends to be low and long diustance masses are high

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 -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [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.

technology is the application of the knowledge gained by science.
