Answer:

the doppler technique

Explanation:

The doppler technique was  an indirect method for finding extrasolar planets and brown dwarfs from radial-velocity measurements using observation of Doppler shifts in the spectrum of the planet's parent star.

Answer:

A Transits

B Doppler technique

Explanation:

The techniques used for the location of extra solar planets are both transit method and the Doppler technique. Extra solar planets are those that orbit a star other than the Sun of our solar system.

Transit method uses the method of measuring light curve from the stars and the reduction of the brightness over time is noted. This is an indirect method.

Doppler technique is a much more  reliable method  to discover exoplanets. It is also called wobble method. This is much more reliable to detect exoplanets. When there is no exoplanet for a given star, the Doppler shift pattern does not change. If exoplanet exists, it changes.

An element emits a spectrum that____________.a)is evenly spaced.b)is the same as all other elements.c)is unique to that element.
Fittoniya [83]

Answer:

c)is unique to that element

Explanation:

 The spectrum emitted by a element shows the internal electronic structure of that element.We know that all element is having different internal electronic structure that is why all element emits different spectrum.And the spacing between the spectrum is uneven .

Therefore the answer will be option C.

c)is unique to that element

What changes a ball velocity
Grace [21]

Answer/Explanation: Speed and direction can change with time. When you throw a ball into the air, it leaves your hand at a certain speed. As the ball rises, it slows down. Then, as the ball falls back toward the ground, it speeds up again. When the ball hits the ground, its direction of motion changes and it bounces back up into the air.

If m = 2,000, p = 2. 25, and y= 6,000, what is velocity?
Karo-lina-s [1.5K]

The velocity is 6.75



The velocity in the equation stated above can be calculated as follows

m= 2,000
p= 2.25

y= 6000

velocity= 2.25 × 6000/ 2000
= 13500/2000
= 6.75


Hence the velocity is 6.75
