The radiation is coming from an incredibly small object. This source supports the idea that the radiation comes from a black hole.

  • The rotating and barycenter of the Milky Way galaxy is known as the Galactic Center (or Galactic Centre).
  • Sagittarius A*, a compact radio source that is almost perfectly at the galactic rotational center, is the galaxy's central massive object and is a supermassive black hole with a mass of roughly 4 million solar masses.
  • Hawking radiation is a result of how quantum fields behave when there is substantial gravity present.
  • Astronomers search for a signal of light from stuff that heats up as it falls into the black hole in order to find this form of radiation, which is only significant for extremely small black holes.
  • SgrA is a radio emission source that is situated in the galaxy's nucleus. Within 1 light year away. , several hundred stars are crowded around it.

bezimeni [28]

Answer:Increase in ambient global temperatures.

Recyling energy to be used again

Regulation of oxygen and carbon dioxide levels

An increase of erosion and siltation along waterways

Explanation:

Conservational biologists think about the preservation of ecosystem by maintaining the environment in a human control way.

Increase in ambient global temperatures.: The humans must prevent the increase in global temperature worldwide by preventing the rise of greenhouse gases which can lead to global warming worldwide.

Recyling energy to be used again: The sources of energy like wood, waste water can be recycled again for reutilization.

Regulation of oxygen and carbon dioxide levels.: The oxygen and carbon dioxide levels must be regulated. As oxygen is the basic requirement for respiration. The increase in carbon dioxide levels due to human activities is likely to cause respiratory diseases and health hazards in living beings.

An increase of erosion and siltation along waterways.: The erosion and siltation will likely to deposit nutrients and debris which may either contaminate the waterway or may cause eutrophication.

The type of sensor the meteorologists should use is Radar sensor.

<h3>Who is a meteorologist?</h3>

A meteorologist is a scientist who studies and works in the field of meteorology with the purpose of understanding or predicting the Earth's atmospheric phenomena.

The tools used by meteorologists in studying atmospheric

phenomena or conditions include:

  • Thermometer for measuring air and sea surface temperature.
  • Barometer for measuring atmospheric pressure.
  • Hygrometer for measuring humidity.
  • Anemometer for measuring wind speed.
  • Pyranometer for measuring solar radiation.
  • Rain gauge for measuring rainfall over a set period of time
  • Radar sensor for observing severe storms.

Therefore, the type of sensor the meteorologists should use is Radar sensor.

In conclusion, a meteorologist should use Radar sensors to detect and predict the atmospheric phenomena in stormy weather.

Calculate the cardiac output if heart rate (HR) is 90 beats per minute, stroke volume (SV) is 110 ml/beat, end diastolic volume
Yakvenalex [24]

ANSWER: None of the above options are correct.

Cardiac Output(CO) = Stroke Volume(SV) × Heart Rate(HR)

Therefore where HR= 90bpm and SV= 110ml/min,

CO = 90 × 110 = 9900ml/min or 9.9L/min.

EXPLANATION:

CARDIAC OUTPUT is the volume of blood being pumped by the heart into the systemic circulation per minute.

Cardiac output is the product of two variables, stroke volume and heart rate.

STROKE VOLUME is the amount of blood pumped out by the left ventricle in each contraction.

HEART RATE is the count of the number of times the heart beats per minute.
