What is an F2 tornado?
F2 is a rating on the Fujita scale, which assess tornado intensity based on damage. The scale runs from F0 at the weakest to F5 at the strongest. F2 indicates a strong tornado (most tornadoes are F0 or F1) that can tear the roof from a well-built house and lift cars off the ground.
Can an F2 tornado tear apart trees and buildings?
Trees can be largely torn apart by an F2 tornado but most buildings will remain standing. An F2 tornado will remove the roof from a typical frame house but leave most walls standing. Weak structures such as mobile homes, barns, and garages will likely be destroyed.
What acceleration occurs if thefriction force is 4 N?
If the friction force is 4 N, the acceleration of the object would depend on its mass. Using Newton's second law (F = ma), if the mass of the object is known, you can calculate the acceleration by dividing the force (4 N) by the mass.
What is the formula for lissajous frequency measurement?
The formula for calculating the frequency of a Lissajous figure is f = (n2-n1) * (f1-f2) / (2 * (n1+n2)), where f is the frequency of the Lissajous figure, n1 and n2 are the integer ratios of the frequencies f1 and f2 on the x and y axes respectively.
How wide and strong is an F2 tornado?
F2 is the beginning of what is called a strong tornado. On the original Fujita scale F2 wind speeds were estimated at 113 to 157 mph. On the Enhanced Fujita scale this was adjusted to 111 to 135 mph, which is believed to correlate better with the damage done. Typical F2 damage includes roofs torn from well-built houses with trailers, barns, and garages completely destroyed. Most walls will be left standing in a well-built house, though weaker ones may collapse. Cars may be lifted and tossed short distances. Large trees will be snapped. Size is not a factor in rating a tornado; ratings are instead based in the severity of the damage done. However, there is a general trend for stronger tornadoes to be larger. F2 tornadoes typically range between 100 yards and a quarter of a mile wide but can be smaller or larger than this in some cases.
What has an enthalpy change that is numerically opposite to the lattice energy of CaF2?
Of these choices:a. Ca(s) + F2(g) → CaF2(s)b. Ca(g) + F2(g) → CaF2(s)c. Ca2+(g) + 2F−(g) → CaF2(s)d. Ca(g) + 2F(g) → CaF2(s)
How do you Balance CaBr2 plus F2 - CaF2 plus br2?
Its already balanced.
How many moles of Ca are there in 0.18moles of Ca F2?
There are 0.18 moles of Ca2+ ions in 0.18 moles of CaF2.
What type of reaction is CaCl2 plus F2--CaF2 plus Cl2?
This is a single displacement reaction where fluorine displaces chlorine in calcium chloride to form calcium fluoride and chlorine gas.
What is the chemical formula for calcium and fluorine?
Fluorine, the element has a symbol/"formula" F. As a charged ion it has a -1 charge = F- Otherwise, fluorine is a diatomic molecule= F2 Calcium is also an element with symbol/"formula" Ca. As an ion it has a +2 charge, so it can be written as Ca2+.
If you rewrite the following word equation as a balanced chemical equation what will the coefficient and symbol for fluorine be nitrogen trifluoride - nitrogen plus fluorine?
The balanced chemical equation would be: NF3 + F2 -> N + 3F2 The coefficient for fluorine would be 2 and the symbol is F2.
Simplify ff plus f plus fff plus f?
Denoting ff as f2 etc, f2 + f + f3 + f = f3 + f2 + 2f
What is the coefficient and symbol of nitrogen trifluoride to nitrogen plus fluorine?
The coefficient is 1 for nitrogen and 3 for fluorine in the balanced equation for the reaction between nitrogen trifluoride (NF3) and nitrogen (N2) to form nitrogen gas (N2) and fluorine gas (F2). The symbol for this reaction is: 2 NF3 + N2 -> 3 F2 + 2 N2
Arrange F2 F2- and F2 plus in order of decreasing stability?
F2 < F2- < F2+. This is because F2 has no extra electrons or missing electrons, while F2- has an extra electron making it more stable than F2. F2+ is the least stable as it has lost an electron, creating an electron deficiency.
Is F2 plus 2 more stable than F2-2?
yes, because it stinks! LOL haha
Is F2 plus NaCl equals NaF plus Cl2 possible or not?
Yes, this reaction is possible. Fluorine will displace chlorine from some compounds.
What type of reaction is HCl plus F2-HF plus Cl2?
The reaction HCl + F2 --> HF + Cl2 is a redox reaction, specifically a single replacement reaction. Hydrogen chloride (HCl) reacts with fluorine (F2) to produce hydrogen fluoride (HF) and chlorine (Cl2).
