What are examples of spore bearing plants? Algae, mosses, and ferns are some examples of plants that produce spores. Although they belong to different clades, they share the same type of reproduction, which is thought to be quite common in the Kingdom Plantae until some groups evolved into seed-bearing plants as another form of reproduction. […]
What liquid will water float on?
What liquid will water float on? Lighter liquids (like water or vegetable oil) are less dense than heavier liquids (like honey or corn syrup) so they float on top of the heavier liquids. The same amount of two different liquids you used in the container will have different densities because they have different masses. Does […]
What is the law of conservation of momentum give an example?
What is the law of conservation of momentum give an example? Conservation of Momentum Examples According to the conservation of momentum, the gun receives a backward momentum. The bullet of mass m is fired with forward velocity v. The gun of mass M acquires a backward velocity u. Before firing, the total momentum is zero […]
What is an example of physical evidence?
What is an example of physical evidence? Examples of physical evidence include a document, a hair, fibers, fingerprints, soil, and blood. Class Characteristics are properties of physical evidence that can be associated only with a group and never with a single source. What are the classification of physical evidence? According to the general nature of […]
Where is the waste product of carbon dioxide being created?
Where is the waste product of carbon dioxide being created? During cellular respiration animal cells combine oxygen with food molecules to release energy to live and function. Remember that cellular respiration produces carbon dioxide as a waste product. Animals use energy to grow, reproduce, and to function. They release the carbon dioxide into the air […]
How is China doing on climate change?
How is China doing on climate change? China, along with 196 countries, agreed to help reduce rising global temperatures and set a goal temperature of 1.5 degrees celsius above pre-industrial temperatures. China has agreed to its NDC goal of reducing the CO2 intensity of its gross domestic product by 60% by 2030. What countries contribute […]
What happens to current during charging and discharging of a capacitor?
What happens to current during charging and discharging of a capacitor? Ans: During the process of charging the capacitor, the current flows towards the positive plate (and positive charge gets added to that plate) and away from the negative plate. While during the discharging of the capacitor, current flows away from the positive and towards […]
How is cubical expansion calculated?
How is cubical expansion calculated? “VOLUMETRIC EXPANSION ” or “CUBICAL EXPANSION”. Consider a metallic body of volume = V1 . Let it’s temperature is raised by T. then experimentally “Increase in volume ( V) is directly proportional to its initial volume (V1) and rise in temperature ( T). What is an example of anomalous Behaviour […]
Do inertial frames exist?
Do inertial frames exist? Such a frame is called an inertial frame. If one such inertial frame exists, then an infinite number of other inertial frames exist since any frame that is moving at a constant relative velocity to the first inertial frame is also an inertial frame. They are called non-inertial frames. Is Earth […]
What are the sources of thermal pollution?
What are the sources of thermal pollution? Some of the important sources of thermal pollution are nuclear power and electric power plants, crude oil refineries, steel melting factories, coal fire power plant, boiler from industries which release large amount of heat to the water bodies leading to change in the physical, chemical and biological characteristics […]
