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.

erik [133]

Answer:

E_total = 1.30 10¹⁰ C / m²

Explanation:

The intensity of the electric field is

     E = k q / r²

on a positive charge proof

The total electric field at the midpoint is

as q₁= 6 10⁻⁶ C the field is outgoing to the right

for charge q₂ = -3 10⁻⁶ C, the field is directed to the right, therefore

E_total = E₁ + E₂

E_total = k q₁ / r₁² + k q₂ / r₂²

r₁ = r₂ = r = 4 10⁻² m

E_total = k/r² (q₁ + q₂)

 we calculate

E_total = 9 10⁹ / (4 10⁻²)²   (6.0 10⁻⁶ +3.0 10⁻⁶)

E_total = 1.30 10¹⁰ C / m²

In the diagnostic radiology energy range (which includes mammography) from 23 to 150 kVp, which of the following tissues possess
Semmy [17]

Answer:

Bone

Explanation:

Diagnostic radiology include the use of non-invasive imaging scans to diagnose a patient.

The voltages used in diagnostic tubes range from roughly 20 kV to 150 kV and thus the highest energies of the X-ray photons range from roughly 20 keV to 150 keV.

The tests and equipment used sometimes involves low doses of radiation to create highly detailed images of an area.
