Which of these statements are true?

A hypothesis is the conclusion of an experiment.

Observation is usually the first step in scientific method.

Dependent and independent variables are the same in an experiment.

Scientists try to understand the phenomena that occur in the environment.

Bias is a judgment that is not based on fact.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
