tankabanditka [31]
The answer to this question should be: Calvin cycle

Calvin cycle is a chemical reaction that was done in the chloroplast of a plant. This is one of the reactions in photosynthesis. In Calvin cycle, carbon dioxide and water will be used to make carbohydrates(glucose).

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.

What have scientists learned from studying seismic waves
Reika [66]
Scientists are able to understand the earth's interior by studying these seismic waves. They are waves of energy that travel through Earth, and actually move similarly to other types of waves, like sound waves, light waves, and water waves.

It’s quite interesting because
they give out lots of useful information.
But really this only scratches the surface on what they can do!

Happy to help!
