A74kv (line-line) three phase short transmission line is 24km long. the line has a per-phase series impedance of 0.1+0.5j ω/km. shunt capacitors are installed at the receiving end to improve the line performance. the line delivers 100mva, 0.8 lagging power factor at 64kv (line-line). question 1 determine the sending end voltage angle δ in degrees when the sending end voltage is 74kv. assume the receiving end voltage angle is 0 deg.

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.
