What type of tide is Australia likely to be experiencing in the diagram on the RIGHT and why? In your own words explain what is happening?
Answer:
Spring tides are extremely high and extremely low. This is created when the sun and moon pull together.
Explanation:
From the diagram, the type of tide Australia is likely to be experiencing is: neap tides.
A tide can be defined as the rise and fall of water level in water bodies such as lakes and oceans, especially due to the gravitational force of attraction exerted by the Moon and Sun on planet Earth.
Generally, there are two (2) main types of a tide and these include:
High tide.Low tide.Additionally, the two (2) form of a tide are:
I. Spring tide: it occur s twice each month close to the the full and new
moons, especially when the Moon and Sun pull together.
II. Neap tide: it occurs two times in a month when the Moon is close to its first and last quarters, especially when the Moon and Sun pull at a right angle.
From the diagram, the type of tide Australia is likely to be experiencing is neap tides because it happened when the Moon is close to its first and last quarters and the Moon and Sun were pulling at a right angle.

Write a short paragraph about electrical current using the terms conductor and insulator.
Answer:
Bet
Explanation:
In a conductor, electric current can flow freely, in an insulator it cannot. "Conductor" implies that the outer electrons of the atoms are loosely bound and free to move through the material. ... Most atoms hold on to their electrons tightly and are insulators.

Celestial bodies emit different types of radiation, only some of which can be detected by traditional telescopes. Radio waves are invisible rays that can be detected only by radio telescopes. A radio telescope functions like a television antenna. Radio waves from space are sensed by a gigantic parabolic reflector, which concentrates them toward the top of a focusing antenna. A radio receptor converts the radio waves into electrical signals which are amplified and then transmitted to the center of the parabola. They are then recorded and analyzed in the laboratory so that scientists can obtain a radio image of the source observed. The parabolic antenna can usually be oriented to detect radio waves from all directions of space. Some radio telescopes are fixed. The largest radio telescope in the world, located in Arecibo, Puerto Rico, is fixed. Built in a natural valley shaped like a giant parabola, its reflector measures 305 meters in diameter. Mobile detectors suspended from cables permit the scanning of one of part of the sky. Unlike traditional telescopes, radio telescopes can be used both day and night, even when there is cloud cover.
Electromagnetic waves can carry more data at higher frequencies. Why would a scientist opt to transmit data at a lower frequency instead?
What are the limitations of sending information using electromagnetic waves?
What are the differences between analog and digital signals?
What are the advantages of using digital signals over analog signals?
Using reliable internet sources, identify three ways we use analog and digital signals in our everyday lives.
Answer:1)The reason as to why scientists opt to transmit data at lower frequency instead of electromagnetic even if it can carry more data at a higher frequencies is because using higher frequencies of electromagnetic spectrum travel shorter distances but have higher data carrying capacity.So this physical characteristic of electromagnetic waves limits the range and availability of frequencies for sending information.
2) Limitations of using electromagnetic waves in sending communication
communication is a process of transmitting and receiving information in the form of signals.high technology communication use electromagnetic waves,there are various types of electromagnetic waves which are used in communication which include radio-waves,microwaves,infrared e.t.c some of their limitations are
i)Because there is limited number of broadcast frequencies the use of transmitters must be restricted in some way or they will seriously interfere with each other.
ii)Through the air signals can be distorted by atmospheric conditions and signals from space are sometimes distorted by solar activity
iii)physical activities such as mountains and buildings can prevent or interfere with some transmissions
iv)Through the air signals are not private,so any tuned receiver within the range can pick up them.
3)Differences between digital and analogue signals
Analogue and digital signal are used to transmit information usually through electric signals.
An analogue signal is continuous wave denoted by sine wave and may varry in signal strength (amplitude) or frequency(time) an example is sound from human voice is analogue because waves are continuous..
A digital signal is a signal in which the original information is converted into a string of bits before being transmitted .example a must for computer processing where is described as using (0s and 1s)and therefore can not take any fractional value.
4)Advantages of using digital signals over analogue signals
one advantage of digital signals are inherently less susceptible than analog signals to interference caused by noise because with digital signal it is not necessary to evaluate precise amplitude,frequency or phase.
Another advantage based in capacity is that digital signals carry more information per second than analogue signals.
Digital signals maintain their quality over long distances better than analogue signals.
5)How we use digital and analogue signals in our everyday live
digital signal processing is the way of life of current generation
example is mobile phones do alot of digital signal processing .they process our our speech digitally to remove background noise,echo e.t.c
Television also do a lot of digital processing of video,audio signal to present them in a better way.
How radio telescopes are used to explore space
A radio telescope is a specialized antenna and radio receiver used to receive radio waves from astronomical radio sources in the sky in radio astronomy.It has several main parts, a dish and antenna,a receiver,a detector and an analyzer.The dish collects the radio signals from space ad focuses them on the antenna.
6)How radio waves are used on earth
Radio waves are used to transmit television and radio programs They have longer wave lengths and are reflected by the ionosphere
7) Reasons why telescopes convert radio waves (analog) to electrical(digital) signals for analysis
This is because signals can be easily stored and transmitted in digital form.The analog is continuous in time and it is necessary to convert this to a flow of digital values.

Answer:
Explanation:
Which water feature is often associated with condensation?
Frozen lakes
The ocean
Clouds and fog
Water vapor rising from plants
Clouds and fog are water features often associated with condensation. The correct option is C.
The process by which water vapour, a gaseous form of water, changes into liquid water is called condensation.
When warm, moist air meets a cooler surface or when the air itself cools, it happens. As a result of this cooling, water vapour loses energy and condenses into tiny water droplets or ice crystals, which are what are seen as clouds or fog.
Even though the ocean and frozen lakes are both connected to water, condensation is not a direct result of either of these. As opposed to condensation, water vapour rising from plants is a result of transpiration.
Thus, the correct option is C.

Write a short paragraph about electrical current using the terms conductor and insulator.
Answer:
An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume. The moving particles are called charge carriers, which may be one of several types of particles, depending on the conductor. An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator have tightly bound electrons whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.
