A mass m = 6.3 kg hangs on the end of a massless rope L = 1.98 m long. The pendulum is held horizontal and released from rest.1) How fast is the mass moving at the bottom of its path?2) What is the magnitude of the tension in the string at the bottom of the path?3) If the maximum tension the string can take without breaking is Tmax = 521.0 N, what is the maximum mass that can be used? (Assuming that the mass is still released from the horizontal and swings down to its lowest point.)4)Now a peg is placed 4/5 of the way down the pendulum

the answer is false

explanation:

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

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.
