# When an electron moves from the ground state to the excited state:_________ a) it emits energy and moves farther from the nucleus. b) emits energy and moves closer to the nucleus. c) absorbs energy and moves closer to the nucleus. d) absorbs energy and moves farther from the nucleus.

d) absorbs energy and moves farther from the nucleus.

Explanation:

Absorption is the phenomenon whereby the energy of a photon is taken by a particle, like an atom, whose valence electrons take this energy, moving from a lower level (ground state) to a higher level (excited state) of electronic energy, moving away from the atomic nucleus.

How long does it take a bird to fly 2.5 km if a bird can fly 23km/h?

Time = Distance / speed

Time =  2.5 km / 23 km/h

= 0.1087 hours                      1 hour = 60 minutes
=  0.1087 * 60 minutes
=  6.522 minutes.

What does a roller coaster have to do with science and energy

A roller coaster has to do with energy is a simple factor. I don't remember the names for it but here's a hint. There's about three ways for it to happen. Energy builds up when a object is not in motion. So thus when it is in motion (when the roller coaster goes down) it creates energy and force which helps pule the roller coaster down in speed.

When we jump on a concrete surface the feet are more seriously hurt than while jumping on a sand

In this situation when using newton's third law, the floor is very rigid and thus when we fall the floor applies the same amount of force on us with which we were falling on it. The rigidness of the concrete floor makes it difficult for it to absorb some of our force. On the other hand sand is not rigid on impact sine it changes its shape while it absorbs a large amount of our falling force and a small fraction of this force is applied on is. That is why we don't get hurt

Which of the following statements best characterizes the surface of the planet Mars?The surface of Mars is continuously resurfaced by ongoing volcanic activity; consequently, there are almost no visible impact craters.All the big volcanoes are in the northern hemisphere of Mars, and most of the craters are in the southern hemisphere.Eighty percent of the surface of Mars is rolling plains, with a number of major volcanoes and only two continent-sized uplands.On Mars there are several moving lithospheric plates rimmed by long mountain chains, deep subduction trenches, and several large rift valleys.

All the big volcanoes are in the northern hemisphere of Mars, and most of the craters are in the southern hemisphere is of the following statements that best characterizes the surface of the planet Mars.

a family backpacking at Yosemite national park took 5 hours to climb a mountain trail 7.5 km long. what was the family's average speed

The average speed will be 1.5km/hr .

Explanation:

Distance need to be traveled = 7.5Km

Time taken = 5 hours

Average speed refers to total distance traveled with respect to total time taken .

It can be calculated as given below :

Average speed =total distance /total time taken

Substituting the values we get ,as shown below

Average speed =7.5/5=75/50

Average speed = 1.5 Km/hr

What does a speedometer measure? A. Average speed B. Acceleration C. Speed D. Velocity

A speedometer measure the instantaneous speed of a vehicle.

Explanation:

A speedometer is a gauge used in vehicles to measure their instantaneous speed. It is basically invented to measure the instantaneous speed of the vehicle such as cars. This is simply the ratio of the distance covered in a unit time.

Its cable gets powered by driveshaft and turned. The cable rotates the magnet at the same speed in the Speed Cup. The hair spring becomes tighter and limits the speed pan to prevent it from turning too much. As the speed cup runs, the arrow raises the dial up to show the vehicle speed.

A speedometer measures speed so the answer is c
