The constant is the temperature of the air that the plants get.

The independent variable is the thing that YOU control.  That's the amount of sunlight each plant gets.

The <em>dependent variable</em> is anything that's caused by changes in the independent variable.  That's the growth of the plants.

Explain diffraction at a single slit (light)
Leto [7]

Answer:

At some point on say, the receiving screen, light emanating from the left side of the slit will be out of phase (a difference of 1/2 wavelengths) from   light coming from the center of the slit.

Thus for every point that is left of the center of the slit, there will be a point on the right side of the slit that is out of phase,

There will be no light on the screen at that particular point and thus there will be a dark fringe there.

That is the basic explanation for the appearance of dark and bright fringes on the receiving screen.

What happened to change people’s views and lead them to believe in continental drift?
Andrej [43]
Aside from Earth-quakes and volcanoes, a scientist noticed how all of the continents fit almost PERFECTLY together. And he used that as evidence to prove the theory of continental drift.

I hope this helps! :)

A specimen of some metal having a rectangular cross section 9.54 mm x 13.9 mm is pulled in tension with a force of 20100 n, whic
Irina18 [472]
<span>Young modulus E = stress/strain where E is the elastic modulus. We seek to calculate the the strain. But we would have to get the stress first. Tensile stress = Force/Area. Force = 20100N. And the Area = 9.54* 13.9 = 132.606Nm^2. Strain = stress/E.where E = 79. Hence we have 132.606/79 = 1.67</span>
