Is Speed affected by medium? speed is constant in a given medium. The speed of waves increase as temperature increases. This is due to the increased kinetic energy of the air molecules and the decrease in density. How does light travel through a medium? Light travels slower in a medium than it does in a […]

What are the advantages and disadvantages of infrared? 1) Infrared transmission requires minimum power to operate and can be set up at a low cost. 2) This is a secure way to transfer data between devices as the signal cannot pass beyond a room or chamber. 1)The speed of data transfer in infrared is slow. […]

What do all land plants have in common? All land plants share the following characteristics: alternation of generations, with the haploid plant called a gametophyte, and the diploid plant called a sporophyte; protection of the embryo, formation of haploid spores in a sporangium, formation of gametes in a gametangium, and an apical meristem. What are […]

What are examples of assumptions? assumption Add to list Share. An assumption is something that you assume to be the case, even without proof. For example, people might make the assumption that you’re a nerd if you wear glasses, even though that’s not true. Or very nice. How do you prove assumptions? The point of […]

Which has more kinetic energy N2 or O2? Since, oxygen and nitrogen are both diatomic, the average kinetic energy of an oxygen molecule is the same as the average kinetic energy of a nitrogen molecule. Thus 20% of the kinetic energy is in the oxygen. The fact that O2 and N2 have different masses does […]

Which out of the following is an example of trade barriers? Option C I.e Tax on imports is the correct answer. The tax which is lieved on the foreign goods at their entry in a country is referred to as Import Tax or tax on imports. It is thus one of the example of trade […]

Where is tissue found in the body? It is present in almost every organ, forming a large part of skin, tendons, joints, ligaments, blood vessels, and muscles. The characteristics of connective tissue and the types of cells it contains vary, depending on where it is found in the body. How many types of tissue are […]

Is it illegal to post homework answers? You can publish questions and answers if you’re the author of both. If you’re not the author of the questions then you can’t publish them — that’s copyright infringment [with no fair use defense]. You can, however, publish your version of the answers and reference the book in […]

What happens if the relative humidity is 100? When relative humidity reaches 100 percent or is saturated, moisture will condense, meaning the water vapor changes to liquid vapor. Thus, the saturation level of air is related to the air’s temperature. As air temperature increases (or becomes warmer), more water remains in a gas phase. What […]

Where should I land on Duna? Traveling to Duna Duna is Kerbin’s second closest neighbor. It is likely your next logical step after landing on the Mun, Minmus, or Eve. It is perhaps the ideal planet for interplanetary voyages for several reasons: Its close proximity to Kerbin. What is the easiest planet to go to […]
