Why does the outer shape of our earth keep on changing? The Earth’s shape changes because the climate events like El Nino shift where the mass of water is stored: in oceans, continents and the atmosphere. What are 4 processes that shape Earth’s surface? Explanation: The four common Planet Surface Processes are: Cratering, Volcanoes, Erosion, […]
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 4 examples of potential energy?
Is P and N directly proportional?
Is P and N directly proportional? Boyle’s law states that pressure (P) and volume (V) are inversely proportional. Gay-Lussac’s law states that pressure (P) and temperature (T) are directly proportional. Avagadro’s law states that the amount (n) of a substance is directly proportional to the volume (V). How do you solve for V in PV […]
Is 11.9 volts enough to start a car?
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 […]
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 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 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 […]
