Tina used 500 N of force to move a desk. The desk weighed 300 N, and she

larisa86 [58]

Answer:

The correct answer is - C. Multiply 500 by 1.5.

Explanation:

Given:

Force to move a desk = 500 N

weight of desk = 300 N

displacement = 1.5 meters

work done by Tine = ?

Formula:

work done (W) = F*d

where F is the force applied on the desk and d is the displacement of the desk.

Solution:

As the displacement is perpendicular to the weight of the desk, therefore, the work done by weight is zero. The work done to the displacement of the desk would be =

W = F*d

= 500*1.5

= 750 J

Thus, the correct answer would be option C.

After 24 hours, the amount of gas that accumulated at the top of the inverted test tube is measured. The students conclude that

vodka [1.7K]

Attached is an image that wherein the question is being referred from.

There are choices for this question namely:

A- gravity increased the downward ﬂow of the trapped water
B- metabolism of the elodea plants absorbed CO2 from the water
C- heat from the light source caused the escape of dissolved gas
<span>D- light caused the elodea plants to photosynthesize, releasing O2 gas
</span>
The correct answer is that light caused the Elodea plants to photosynthesize, releasing O2 gas. Choice A is not true as if gravity increased the downward flow of the water, then the model without light should have air accumulated in the test tube too. In Choice B, while it is true that the plant may have absorbed the dissolved CO2 in water, this does not explain why there is gas on top of the test tube. Choice C may only evaporate the water, not cause the escape of dissolved gases. In choice D, however, light caused the Elodea plants to perform photosynthesis releasing O2 gas compared to the other model without light wherein the plant cannot perform photosynthesis thereby not releasing O2 gas therefore no gas is seen on top of the test tube.
