What kind of charging occurs when you slide your body across a plastic surface? Electrostatics: When a person slides across a plastic surface, the plastic produces a net negative charge and your body surface a net positive charge. What will happen if you switch the battery so that the positive end is on the right […]
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 […]
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 […]
Why does river discharge increase downstream?
Why does river discharge increase downstream? Changes Downstream As one moves along a stream in the downstream direction: Discharge increases, as noted above, because water is added to the stream from tributary streams and groundwater. As discharge increases, the width, depth, and average velocity of the stream increase. Why are river profiles concave? River profiles […]
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 affects condensation?
What affects condensation? Two things must be present for condensation to occur: warm moist air, and cool surface temperatures below the dew point. The proper control of these two factors can minimize condensation. What is the main cause of condensation? Condensation occurs when warm air collides with cold surfaces, or when there’s too much humidity […]
What three structural groups shown do all amino acids have in common?
What three structural groups shown do all amino acids have in common? All amino acids have the same backbone structure, with an amino group (the α-amino, or alpha-amino, group), a carboxyl group, an α-hydrogen, and a variety of functional groups (R) all attached to the α -carbon. What are the 4 major biological macromolecules? Types […]
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 […]
