A train takes ms eaddy 200 miles north and 150 miles south. The total trip took 3.5 hours what was the average velocity of the train in MPG?

Answers

Answer 1

Answer: The whole point of this problem is to check how well you understand
the definitions of a few important quantities, like velocity, speed, distance,
displacement etc.

Before we begin, I just want to mention that 'MPG' is not a unit of either
velocity or speed, but I think I know what you mean.

-- For some reason, Ms. Eaddy rode 100 miles north on the train, then
stayed aboard while the train turned around and took her 150 miles south.
The total distance she rode was (100 + 150) = 250 miles. But she ended up
50 miles south of where she began.

-- Displacement for the whole trip = distance and direction from the start point
to the finish point.

Displacement = 50 miles south

-- Average velocity = (displacement) / (time)

50 miles south / 3.5 hours = 14.29 miles per hour south

True or false: distance traveled and displacement can be equal.

Answers

Answer:

true

Explanation:

Answer:

When the object is moving in a straight line distance will be equal to displacement. ... Shortest path = Actual path,because object travelled in a straight line. Displacement and Distance should have same magnitude because the object has not changed its direction.

What is the independent variable?
And what is the dependent variable for this experiment

Answers

Answer:

Independent variable - temperature

Dependent variable - tablet dissolving affect.

Explanation:

The Independent variable in an experiment is characterized as the variable in the experiment that is not affected by a change in any other variable or factor. It could be changed or manipulated to observe its impact on the dependent variable. While a dependent variable is the one that is affected by any change in the independent variable.

In the given experiment, the 'temperature' is the independent variable as it can be controlled or manipulated to observe the effect in the dependent variable. The 'tablet dissolving effect' would be the dependent variable as it is directly affected by any change in the independent variable(the higher the temperature, the easier the tablet gets dissolved).
