An automobile moving at 20m/s slows to a stop in 6.5
seconds. find the acceration of the car.

-3.1 m/s²

Explanation:

Given data

We can determine the acceleration of the automobile using the following kinematic expression.

a = Δv / t

a = vf - v₀ / t

a = (0 m/s - 20 m/s) / 6.5 s

a = -3.1 m/s²

the child will have heterozygous dominant chromosomes as characters of his father are dominant over the characters of his mother.

the child is heterozygous

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
