While rowing in a race, John pulls the handle of an oar 0.80 m on each
stroke. If the oar has a MA of 1.5, how far does the blade of the oar move
through the water on each stroke?

According to the question,

Input distance,

Mechanical advantage,

The output distance is:

=

By putting the values,

=

=

Thus the above answer is right.

Stroke D (Output Distance) = 0.533 meter (Approx)

Explanation:

Given:

Stroke D (Input Distance) = 0.80 meter

Mechanical advantage (MA) = 1.5

Find:

Stroke D (Output Distance) = ?

Computation of Stroke D (Output Distance) :

⇒ Stroke D (Output Distance) = Stroke D (Input Distance) / Mechanical advantage (MA)

⇒Stroke D (Output Distance) = 0.80 meter / 1.5

⇒ Stroke D (Output Distance) = 0.533 meter (Approx)

the answer

explanation:

the capillary tube was too close to the bottom of the beaker.

the ruler may have moved.

water got into the capillary tube.

the temperature was not allowed to equilibrate in the 2-4 minutes.

it would be a gas formation
