The table below shows data of sprints of animals that traveled 75 meters. At each distance marker, the animals' times were recorded. Which animal is showing the greatest average acceleration from the 25-meter mark to the 50-meter mark? (2 points)

Animal 25 meters 50 meters | 75 meters
Animal 13 seconds 3.5 seconds 5 seconds
Animal 24.5 seconds 5.5 seconds 5.75 seconds

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

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.

i would say
