Daisy made the graph shown to display the data recorded during an experiment. Daisy is studying the effect of soil on the growth

of plants. Three identical plants having a height of 15 cm were used for the experiment. The first plant was planted in Type A soil in 4 hours of sunlight, the second plant was planted in Type B soil in 6 hours of sunlight, and the third plant was planted in Type C soil in darkness. All other growing conditions of the plants were kept constant.
A bar graph titled Plant Growth is shown. The y axis, labeled Height in centimeters, goes from 0 to 3.50. The x axis, labeled Week, goes from 1 to 4. Each week has 3 bars, Type A soil, Type B soil, and Type C soil. For weeks 1 to 4, bars for Type A soil have heights of 1.25 centimeter, 1.50 cm, 1.75 cm, 2.00 cm, bars for Type B soil have heights of 2.00, 2.25, 2.50, and 2.75 centimeters, and bars for Type C soil have heights of 0.50, 0.75, 1.00, and 1.75 centimeters.

Which step in Daisy's scientific method was incorrect? A single variable was used Sunlight was not kept constant More than one type of soil was used Other growing conditions were not changed

Answer:

The Sunlight was not kept constant.

Explanation:

Plants generally respond to stimuli, and majorly require sunlight during the process of photosynthesis. That is why the growth of the plants was affected by the rate exposure to sunlight.

The gravitational force of a star on an orbiting planet 1 is F1. Planet 2, which is twice as massive as planet 1 and orbits at t
Andrej [43]

Answer:

ratio = 1 : 4.5

Explanation:

If m₁ is the mass of the star and m₂ the mass of the planet, the force of gravity F₁ for planet 1 is given by:

F_1=\frac{Gm_1m_2}{r^2}

The force F₂:

F_2=\frac{Gm_1(2m_2)}{(3r)^2}

The ratio:

\frac{F_2}{F_1}=\frac{2}{9}

"In a pure substance all the particles must be identical; therefore pure substances are composed only of elements." Do you agree
kenny6666 [7]

I do not agree with the statement.
The "substance" can be a compound.  It's "pure"
as long as there's nothing else in it but its name.

'Pure' water is 100% H₂O with nothing else in it.
'Pure' table salt is 100% NaCl with nothing else in it.
'Pure' carbon dioxide is 100% CO₂ with nothing else in it.

These example substances are all compounds, not elements.
