How did changing the speed to crank the generator affect the intensity and glow of light bulbs?

Answers

Answer 1
The bulb with get brighter. Power is equal to 2/
V
2
/
R
, so if you increase V and R at the same rate then power will increase. Note that with real incandescent light bulbs the resistance of the filament increases a lot from the bulb's "off" state to its "on" stage due to the fact that the resistance depends on temperature.

Answers

Answer:

the suns on the other side of the earth at the time

Explanation:

hope it helps :)

Answer:

The Earth is tilted at an angle of about 23 degrees, which means that depending on where Earth is on its orbit, one pole will be getting more hours of light (summer) and one will be dark (winter).

Explanation:

Also, the earth is tilted on it's axis so more direct rays of sunlight hit the southern hemisphere making it summer in that hemisphere while it is winter in the northern hemisphere.  Six months later, this reverses, and more direct rays hit the northern hemisphere.  That's why it's summer here while it's winter there.  

The earth's distance from the sun has nothing to do with it.  It's all about the axial tilt.

Due to its location, Hawaii does not have very many land birds. The Hawaiian honeycreepers are a favorite for many ornithologists. There are over 50 species of honeycreepers that can all be traced back to one ancestor. The level of diversity in an ecosystem can be determined by the frequency of speciation and extinction.

Describe speciation and identify two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to speciation.
If the Hawaiian honeycreepers became extinct, explain how the newly available niches could lead to speciation.

Answers

Answer:

In speciation, organisms evolved with the passage of time.

Explanation:

Speciation is the evolutionary process in which populations of species evolve with the passage of time to become different species from the original one.  Temporal isolation and gametic isolation are two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to occur speciation. The newly available niches could lead to speciation of that organisms that tolerate the Hawaiian climatic conditions when the extinction of Hawaiian honeycreepers occurs. The new organisms used the available resources such as food and space etc and increase its population.

Mammals really spread and diversified during the Cenozoic era. So, the correct option is D.

What was Cenozoic era?

The Cenozoic Era is defined as the third of the major eras in Earth's history that began about 66 million years ago and extends to the present. This epoch was the interval of time during which the continents assumed their modern configurations and geographic positions during which the Earth's flora and fauna evolved towards the present.

The Cenozoic Era is called the "Age of the Mammals", while the typical landscapes of North America began to develop during the Cenozoic. Birds and mammals rose to prominence after the extinction of giant reptiles.

Thus, Mammals really spread and diversified during the Cenozoic era. So, the correct option is D.
