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.

The axoplasm of an axon has a resistance Rax. The axon's membrane has both a resistance (Rmem) and a capacitance (Cmem). A singl

dybincka [34]

Answer:

The expression is Vmem = ΔV - I*Rax

Explanation:

According to the picture, if switch S is closed, the Cmem will be short. If Vcap = 0, the current flows through the capacitor only (not through Rmem), thus Vmem = 0 after closing S.

When C is fully charged, then we have:

Vmem = ΔV - I*Rax

A constant amount of charge passes through a conductor. How is current affected if the same amount of charge passes in less time

baherus [9]

Answer:

B. The current increases.

Explanation:

As we know that rate of flow of charge through the conductor is known as electric current

So we have

$i = \frac{q}{t}$

here we know that charge Q flowing through the conductor is constant while the time in which it passes through it is decreased

so we can say that the ratio of charge and time will increase

so here we have

$i = increased$

So correct answer will be

B. The current increases.

How does Newton's first law affect human motions answer

vazorg [7]

The First Law states, "A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force." This simply means that things cannot start, stop or change direction all by themselves. It requires some force acting on them from the outside to cause such a change. Hope this helps! Mark brainly please!
