The distance versus time plot for a particular object shows a quadratic relationship. which column of distance data is possible for this situation? time (s) a. distance (m) b. distance (m) c. distance (m) d. distance (m) e. distance (m) 0 0 2.00 9.00 ‡ ‡ 1 1.00 4.00 18.00 1.00 1.00 2 4.00 6.00 27.00 0.50 0.25 3 9.00 8.00 36.00 0.33 0.11 4 16.00 10.00 45.00 0.25 0.06 5 25.00 12.00 54.00 0.20 0.04 6 36.00 14.00 63.00 0.16 0.02 column a column b column c column d column e

Explanation:

In a quadratic relation , variable y is directly proportional to x^2

distance time have the relationship

d = kt²

or

t = kd²

where k is a fixed number (constant).

column A has the perfect squares

: 1, 4, 9, 16...

Therefore d = kt² with k=1:

t = 0, d = 1 x 0² = 0

t = 1, d = 1 x 1² = 1

t = 2, d = 1 x 2² = 4

t = 3, d = 1 x 3² = 9

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.

god i hope this !
