On agile projects, detailed risk management activities may occur during all of the following times except:

a. While planning each subsequent iteration.
b. In daily stand-up meetings.
c. During retrospectives at the end of each iteration.
d. During early risk planning at the start of the project.

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.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
