Answer:

I would use the model of Ammonia because it helps you visualize the structure of NH3 better than the description. It would be easier to understand the structure of it if you can see it, rather than reading its description.

If the electrons are attracted more by the nucleus because of an additional proton, what would happen to it?
Rus_ich [418]

Answer:

orbital speed of the electrons in their orbit will increase

Explanation:

As we know that centripetal force for electrons will be due to electrostatic attraction force of electron.

So it is given as

F_e = F_c

so we have

\frac{(Ze)(e)}{4\pi \epsilon_0 r^2} = \frac{mv^2}{r}

now on the left side if the force of attraction will increase and hence there must be the change in that part of equation

So here at the same position the speed of the electron

So we can say that correct answer will be

orbital speed of the electrons in their orbit will increase

A star is estimated to be 4.8 km away from the earth. When we see this star in the night sky how old is the image. Let the speed
andre [41]

Time = distance / speed

Time = (4,800 meters) / (3 x 10⁸ m/s)

<em>Time = 0.000016 second</em>

This number is not one of the choices on the list.  My hunch is that you copied the distance wrong.

If the estimated distance to the star is actually 4.8 x 10¹⁵ km, instead of 4.8 km, then the answer would be close to 500 years <em>(B)</em>.

There's no way a star can be "4.8 km away from the Earth".  You can <em>walk</em> that far in about an hour, and passenger jet airplanes fly <em>twice</em> as far as that away from the Earth !
