How are stars distributed throughout an elliptical galaxy?

1 answer:

6 0

An elliptical galaxy is a type of galaxy having an approximately ellipsoidal shape and a smooth, nearly featureless brightness profile. Unlike flat spiral galaxies with organization and structure, they are more three-dimensional, without much structure, and their stars are in somewhat random orbits around the center.

torisob [31]

Answer:

This satisfy the above given condition so we can say that this capacitor.

Explanation:

Let's take one by one option and check whether is wrong or right

For inductor:

$I=I_osin(wt-\frac{\pi }{2})$

Given that at t=T/4 ,I=0 and we know that

$w=\dfrac{2\pi }{T}$

So at T/4

$I=I_osin(\frac{2\pi }{T}\times \frac{T}{4}-\frac{\pi }{2})$

I=0 A

At t=T/2

$I=I_osin(\frac{2\pi }{T}\times \frac{T}{2}-\frac{\pi }{2})$

$I=I_o$

It means that this not a indutor.

For capacitor:

$I=I_osin(wt+\frac{\pi }{2})$

At T/4, I=0

At t=T/2

$I=I_osin(\frac{2\pi }{T}\times \frac{T}{2}+\frac{\pi }{2})$

$I= -I_o$

This satisfy the above given condition so we can say that this capacitor.

What is the name given to the portion of the electrocardiogram between two waves?.

olya-2409 [2.1K]

Segment

The space between two waves is known as a segment in an ECG. Beginning at the end of the P wave and ending at the beginning of the QRS complex is the PR segment. Beginning at the end of the QRS wave and ending at the beginning of the T wave is the ST segment.

An electrocardiogram (ECG) is a quick test that can be used to examine the electrical activity and rhythm of your heart. The electrical signals that your heart beats out each time it beats are picked up by sensors that are affixed to your skin.

A test that captures the electrical activity of the heart is called an electrocardiogram (ECG). The ECG shows what is occurring in various heart regions and aids in identifying any issues with heart rate or rhythm.
