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 […]
What is simple harmonic motion write its any four characteristics?
What is simple harmonic motion write its any four characteristics? (i) In SHM, acceleration of the particle is directly proportional to its displacement, and directed towards the mean position. (ii) It can be represented by a single harmonic function of sine or cosine. (iii) Total energy of the particle executing SHM remains conserved. (iv) It […]

What are examples of spore bearing plants?
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. […]
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 […]
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 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 […]
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 type of weather does the California Current bring?
What type of weather does the California Current bring? The California Current moves less water than the Gulf Stream does. But the California Current has a big effect on the climate of the West Coast of the United States. Usually, the climate along the West Coast is cooler than the climate of inland areas at […]
