Answer:
<u>diode</u>: It passes current only in one direction.
<u>resistor</u>: Is the most commonly used electronic element. It is used to limit the electric current flowing in the electronic system.
<u>transistor</u>: It strengthens the current in the receivers, it can also turn it on and off. This element has three tips, which we call the base, collector and emitter.
<u>capacitor</u> : Has the ability to store electricity and can release it when needed. Next to the resistor, it belongs to the most commonly used elements in electronic devices.
Explanation:
Diode is a substance which is half conductor and half insulator that is used to compel the current to flow in only one direction. Resistor is a device which is used for controlling flow of current through circuit. Capacitor is a device which is used as a storage device which provides extra electricity to machine when it is required. Transistor is a device which is used to amplify or switch electronic signals and electrical power.
Answer:
Option (4)- I and III only
Explanation:
Evapotranspiration is the process by which the plants after absorbing water and carbon dioxide, release the excess water back into the atmosphere. It helps in synthesizing their own food.
The freshwater reserves on the earth's surface are constantly being exploited by humans. The groundwater is exhausted due to pumping and the surface waters are contaminated by the waste materials that are produced from the industries and factories that mix with the rivers and streams. It is also used up for the agricultural purposes
Sublimation is not a process of taking in water vapor by the roots. But it is a phase transition process from solid to gas or gas to solid.
Hence, the correct answer is option (4) i.e I and III only.
Answer:
A. culture . . . environment
Explanation:
Boston, including its harbor and the land area surrounding it, have experienced lot of changes over the course of the past few centuries. The people of course have been responsible for these changes, as they have been the ones performing the actions that led to the changes, based on their culture, perceptions, and needs.
Every culture has its own unique characteristics and trademark features, and that is almost always seen in the manner in which the environment is changed by the humans. The culture pretty much dictates what will be built, how it will be built, the organization, the aesthetics, the meaning. Simply said, the culture is a key component of the changes inflicted on the environment by the humans.
Answer:
Plate Tectonic theory
Explanation:
Plate tectonics is based on continental drift, and seafloor spreading the three pieces of evidence that support this are those given by Alfred Wagner
As the Jigsaw fit between continents that were one at some point in time.
As the polar wandering or the flight to poles i.e how continents are drifted way to poles by forces of wind.
Presence of the same flora and fauna and glacial valley formation that were once a part of the same continent of Pangea and Gondwana.
The hypothesis ultimately got replaced by seafloor spreading as the drawbacks of drift theory which would not give sufficient evidence for the spreading away of continents. Earth's tectonic forces and internal sources of energy i.e heat produced by radioactive decay was not emphasized and Alfred's continuous orogeny could not have been possible.
The effect of natural regions on the distribution of population in Australia and New Zealand is as a result of pattern of urban distribution .
<h3>What is the distribution of population in Australia?</h3>
The distribution of population in Australia can be attributed to the pattern of urban distribution, whereby people tend to prefer to stay at the urban region compare to the rural areas.
However some people still prefer to stay at the rural region for the sake of agricultural practices.
