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 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 […]
Are aluminum bats allowed in Major League Baseball?
Are aluminum bats allowed in Major League Baseball? Aluminum bats are used in college, high school and little league ball, but they’re illegal in the major leagues where hitters must use wooden bats. The issue is the velocity with which balls come off the bat, otherwise known as bat-exit speed. Where do you bat your […]
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 […]
Is 100 degrees Celsius hot?
Is 100 degrees Celsius hot? No. We can say that the temperature of boiling water is 100°C(or 100 K) more than the temperature of ice cold water. The highest temperature obtained in the large hadron collider is 5.5 trillion degrees Celsius while the temperature on the surface of sun is 5600°C. However, sun has much […]
What is the difference between successful people and normal people?
What is the difference between successful people and normal people? Ordinary people set goals, successful people set detailed plans of actions. Successful people set their goals as well. More importantly, however, they create a detailed set of actions they need to perform in order to achieve their end goal. What is the difference between ordinary […]
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 […]
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 […]
