Can a planet break? Is it possible for a planet to break apart? Yeah. There are small planetary bodies in the solar system that are tight clouds of rocks, ice and other solid matter in a that orbit close enough that they have a gravity well. What is unique about Janus and Epimetheus? Epimetheus and […]
What is the main weakness of transmission models of communication?
What is the main weakness of transmission models of communication? Transmission models treat decoding as a mirror image of encoding, allowing no room for the receiver’s interpretative frames of reference. Where the message is recorded in some form ‘senders’ may well have little idea of who the ‘receivers’ may be (particularly, of course, in relation […]
Is it good to have electoral competition?
Is it good to have electoral competition? Yes, it is good to have political competition. A political competition may have many limitations such as it can results in factionalism, disunity and use of dirty tricks to win elections. However, free competitions in elections works better in a longer run. What are the advantages of competition? […]
What is the most important instrument for comparing bullets?
What is the most important instrument for comparing bullets? These bullets are then examined using a comparison microscope. The firearms examiner’s best tool is the comparison microscope, which is used to examine two different objects, bullets in this case, simultaneously. This lets the examiner compare the striations left on the fired bullets (2). Does the […]
Why does dynamic equilibrium occur?
Why does dynamic equilibrium occur? In chemistry, and in physics, a dynamic equilibrium exists once a reversible reaction occurs. Substances transition between the reactants and products at equal rates, meaning there is no net change. Reactants and products are formed at such a rate that the concentration of neither changes. What is the dynamic equilibrium […]
Which two factors are responsible for many of the unique physical and chemical properties of water?
Which two factors are responsible for many of the unique physical and chemical properties of water? Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density. What are 3 physical properties of water? 1 Physical Agents. Physical […]
Which cable is used in ring topology?
Which cable is used in ring topology? coaxial cable Which topology is best? star topology Which topology is fastest? Which topology is used in schools? Ring Network Topology Ring network topologies are most often found on school campuses, though some commercial organizations also use them. FDDI, SONET, or Token Ring technology are typically used. Which […]
What is the value for acceleration due to gravity?
What is the value for acceleration due to gravity? 9.8 m/s2 Do astronauts wear G suits? Image to left: Astronauts wear G-suits to help prevent dizziness. They also wear rubberized full-body suits, called “G-Suits,” that can be inflated with air. The suit squeezes arms and legs to push the blood back and balance the pressure. […]
What is the period of 440 Hertz?
What is the period of 440 Hertz? 1 Hertz corresponds to 1 oscillation/second. Once we understand the meaning of a pitch or frequency of 440 Hz, we can ask a related question: how long does 1 oscillation of the vibrating string take? If the string oscillates 440 times in 1 second, then each oscillation will […]
Where do electromagnetic waves come from?
Where do electromagnetic waves come from? Description: Electromagnetic waves are formed when an electric field comes in contact with a magnetic field. They are hence known as ‘electromagnetic’ waves. The electric field and magnetic field of an electromagnetic wave are perpendicular (at right angles) to each other. Is all energy electromagnetic? All of the energy […]
