Explain the astrometric method that astronomers use to search for other planetary systems that orbit a star.

Physics

Answer:

Transit Method

Explanation:

Most of the planets revolving around the other stars are found using transit method. Since stars are very bright and bigger in comparison to any planet revolving around them. Observing them directly is not possible. In transit method astronomers look for opportunities when these planets transit across the stars as seen from Earth. Because of this transit the brightness of the star will appear to dip. With the help of the duration of the dip and frequency of the dip astronomers find out the size and orbital period of such planets.

Some of the exoplanets are found using wobble method and direct imaging as well.

The placebo effect can weaken the _____ of an experiment.
erik [133]
The answer to this question would be: internal validity
Placebo effect happens when someone feels that they are getting better just because they got a drug, not by the substance inside the drug. That means even if the drug is empty the person can feel that it works.
Placebo effect can decrease the actual effect of the drug, thus decreasing the internal validity.

light that is polarized along the vertical direction is incident on a sheet of polarizing material. only 87% of the intensity of
nekit [7.7K]

Polarized light waves are those that have only one plane of vibration. Polarization is the process by which non-polarized light is converted into polarised light. There are numerous ways to polarise light.

A characteristic of transverse waves called polarisation identifies the geometric angle of the oscillations. A transverse wave's oscillation direction is perpendicular to the wave's motion direction.

given

Only 72.0% of the light's intensity makes it through the sheet and hits another sheet of polarising material. The second sheet lets no light flow through it.

Given that no light passes through the second sheet because both sheets are crossed, the angle the transmission axis of the second sheet makes with the vertical is

θ₂ = θ₁ + 90°

   = 31.94° + 90°

   = 1 21.94°

for the first sheet and

Icos²θ₁ = I

I/I₀ = 0.72

θ₁ = cos⁻¹√(0.72)

    = 31.94°

for the second sheet, respectively. This is because the malus law states that I = Iocos²θ₁ for the first sheet.

Swamps and other wetlands do not offer much value to humans. True or false?
uysha [10]

The statement 'Swamps and other wetlands do not offer much value to humans' is FALSE.

<h3>What are Swamps?</h3>

Swamps and other wetlands are specific ecosystems that are abundant in biodiversity and therefore offer many advantages.

Biodiversity is fundamental to discovering new biotechnological applications and therefore swamps are fundamental for humans.

In conclusion, The statement 'Swamps and other wetlands do not offer much value to humans' is FALSE.
