Answer: Ethical concerns affect scientific research when scientists or groups of scientists let their personal bias or political persuasions affect the research being conducted. Scientific ethics involve doing experimentation and analysis of data without bias no matter what the conclusions point to.
Answer:
0.21 kg
Step-by-step explanation:
Volume of cola = 2.0 L × (33.8 fl oz/1L)
= 67.6 fl oz
Grams of sugar = 67.6 fl oz × (25 g sugar/8.0 fl oz)
= 210 g sugar
Kilograms of sugar = 210 g × (1 kg/1000 g)
= 0.21 kg
Answer:
pH = 10
The solution is basic.
Explanation:
A solution contains 1 × 10⁻⁴ M OH⁻ ions. First, we will calculate the pOH.
pOH = -log [OH⁻]
pOH = -log 1 × 10⁻⁴
pOH = 4
We can find the pH of the solution using the following expression.
pH + pOH = 14.00
pH = 14.00 - pOH = 14.00 - 4 = 10
Since the pH > 7, the solution is basic.
- The wavelength range of Infrared radiation is 700 nanometers to 1 millimeter.
- The sun emits mainly near-infrared which is mainly composed of wavelength below 4 micrometers.
- The thermal range of infrared ranges between wavelengths 3.5 and 2.0 micrometers
Explanation:
The wavelength range of Infrared radiation is 700 nanometers to 1 millimeter. This also translates to a frequency range of 430 TeraHertz to 300 Giga Hertz.
Because the sun is a star and is hot in comparison to earth and other planetary bodies, the bigger range of infrared radiation it emits is in the near-infrared which is mainly composed of wavelength below 4 micrometers.
The earth's surface produces infrared radiation of the mid-infrared range while cooler substances will produce far-infrared range
The thermal range of infrared ranges between wavelengths 3.5 and 2.0 micrometers and is produced by black bodies.

Answer:
Explanation:
Hello,
In this case, the Boyle's is mathematically defined via:
Which stands for an inversely proportional relationship between volume and pressure, it means the higher the volume the lower the pressure and vice versa. In such a way, since the volume is decreased to one quarter, we can write:
We can compute the new pressure:
Which means the pressure is increased by a factor of four.
Regards.
