Julie wanted to know if adding calcium fertilizer to tomato plants will help prevent a disease of tomato plants called blossom-e

nd rot. She used 10 tomato plants. She put 5 plants in a sunny part of the garden and gave each one calcium fertilizer once a week. She placed the other 5 plants in a shady part of the garden and gave them calcium fertilizer twice a week—she thought that since they were in the shade they might need more fertilizer. She then observed the 10 plants for 3 months to see if the fertilizer helped prevent blossom-end rot. Identify and explain one weakness in Julie's experimental design.

Jlenok [28]

Answer:

-30°C

Explanation:

F-32/180 =C-0/100

or, -22-32/180=C/100

or, -54/180*100=C

or, -0.3*100=C

therefore, C= -30

-22°F = -30°C

What's the Coulomb's law?
Ulleksa [173]

<span>
In layman's term: </span>like charges don't attract while opposite charges do<span>electrostatic forces between point A( which is charged) and point B (which is also charged) are proportional to the charge of point A and point B. </span><span>there is also something else about this  law that I don't quite remember.</span>

<span>___________________________________________________</span>

<span />Here is the formula:

<span>F = k x Q1 x Q2/d^<span>2</span></span>

<span>What the formula means:</span>

F=force between charges

Q1 and Q2= amount of charge

d=distance between these two charges

k= Coulombs constant (proportionally constant)

________________________________________________

I think that about covers it and hopefully this helped.
