Answer:
In summary kinetic energy is not necessary
Explanation:
In this problem we are asked to indicate what type of energy does not need to be considered.
As they indicate that the masses do not move, scientific energy is defined by
K = ½ m v²
Since the velocities of the mass are zero, this energy is zero, so it is not necessary to take them into account in our analyzes.
In summary kinetic energy is not necessary
Answer:
The voltage drop across the bulb is 115 V
Explanation:
The voltage drop equation is given by:
Where:
ΔW is the total work done (4.6kJ)
Δq is the total charge
We need to use the definition of electric current to find Δq
Where:
I is the current (2 A)
Δt is the time (20 s)
Then, we can put this value of charge in the voltage equation.
Therefore, the voltage drop across the bulb is 115 V.
I hope it helps you!
Answer and Explanation:
The distinction between Endangered species and Extict species is Given as under:
Endangered Species:
Endangered species are categorized as those species of flora and fauna which are on the verge of extinction if not provided timely protection in order to save them from getting extinct.
Some of the endangered species are African Penguin, Bengal Tiger, Blue Whale, etc
Extinct Species:
Those species of Flora and Fauna which have vanished completely or either from the wild i.e., that individuals of that species are not alive any more and have completely disappear from the earth.
In practice, if a species is not seen for over a period of 50 years it is considered to be extinct.
Some of the extinct species are Dodo, Passenger Pigeon, Great Aulk, etc.
Answer: Aerial plants is plants that lives in air or wind the wind serves as the water of the plants. Most aerial plants are found in tropical and equatorial regions of the world. In evergreen rain forests, the foliage is so thick that some plants have evolved aerial roots to allow them to absorb more sunlight. The development of aerial roots is
thus an evolutionary process.Aerial roots are often thick and spread around the parent tree. The Banyan tree can have several aerial roots as it gets older.
