Can levees be man-made? Levees can be natural or man-made. Larger material is deposited closest to the river bank. Natural levees are ridges along river banks that form from rapid deposition from overbank flow. during times of high rainfall the river’s capacity will be exceeded and the river will flood onto the floodplain. What are […]

Do fish ever get bored? But whether fish actually feel bored in a way we can relate to is harder to work out. This could be the aquatic equivalent of the pacing of a captive tiger that’s bored from a lack of stimulation. But the fish could also be stressed from an overcrowded or unfamiliar […]

Why do computers only understand 1 0? The circuits in a computer’s processor are made up of billions of transistors . A transistor is a tiny switch that is activated by the electronic signals it receives. The digits 1 and 0 used in binary reflect the on and off states of a transistor. What are […]

Which plants grow very low to the ground and have no true roots and no true leaves? Mosses are typically soft plants that grow in clumps or mats. Like other plants, they produce chlorophyll and undergo photosynthesis, but they do not have true roots. They instead have multicelled, rootlike appendages called “rhizoids,” which anchor the […]

Is the Ncvs reliable? Research based on interviews of victims obtained from police files indicates that assault is recalled with the least accuracy of any crime measured by the NCVS. What are the limitations of the Ncvs? A limitation of the NCVS data stems from the fact that they are derived from a sample. Like […]

Where is basalt commonly found? It is found all over Earth, but especially under the oceans and in other areas where Earth’s crust is thin. It formed in the Isle Royale-Keweenaw region because of the Midcontinent Rift. Most of Earth’s surface is basalt lava, but basalt makes up only a small fraction of continents. What […]

What is the formula for diffusion? rate(gas A) × √molar mass(gas A) = rate(gas B) × √molar mass(gas B) This means that the relative rate of diffusion of two gases can be used to determine their relative molecular mass (or molar mass). Which gases will have the slowest effusion rate? Three gases were used: hydrogen, […]

What is the most densest element? element osmium What is the lightest natural metal? magnesium What are the 3 lightest metals? The first seven metals in the periodic table are lithium, beryllium, sodium, magnesium, aluminium, potassium and calcium, known collectively as the “lightest metals”. What is the lightest thing in the world? Graphene Aerogel What […]

What is the final velocity of the two vehicle mass? A 1500 kg car traveling at 15 m/s to the south collides with a 4500 kg truck that is intially at rest at a spotlight. The car and the truck stick together and move together after the collison. Therefore, the final velocity of the two-vehicle […]

What is the common ratio for this geometric sequence 4 24 144? = 6 (answer). What is the formula of common difference? The common difference is the value between each number in an arithmetic sequence. Therefore, you can say that the formula to find the common difference of an arithmetic sequence is: d = a(n) […]
