5 0

Answer:

320m

Explanation:

The vertical displacement is given by:

y_0-y=\frac{1}{2}gt^2-v_0t

Assuming v₀=0, t=8:

y_0-y=\frac{10}{2} \times 8^2 + 0\times 8 = 320

What is the chemical name for N2O3? nitrogen trioxide dinitrogen trioxide pentanitrogenoxide nitrogen oxide
charle [14.2K]

Answer: The chemical name for N2O3 is dinitrogen trioxide.

Explanation:

Nitrogen occurs chiefly as a free element in the air, making up about 78% by volume of the atmosphere. Nitrogen forms several oxides with oxygen. The formation of these oxides by the direct combination of nitrogen and oxygen required very high temperatures. Examples of oxides of Nitrogen includes:

--> Nitrogen (I) oxide: N20

--> Nitrogen (II) oxide: NO

--> Dinitrogen trioxide: N2O3.

When naming a chemical compound the number of elements in the compound is put under consideration using prefixes such as di (2), Tri(3), tetra(4), penta(5). From the chemical formula N2O3, there are 2 nitrogen atoms and with +3 oxidation state. Hence, the name DINITROGEN TRIOXIDE.

A 1234 kg freight car moving at 6 m/s runs into a 2468 kg freight car at rest. They stick together upon collision. What was the
kirill [66]

Answer:

2 m/s

Explanation:

Applying,

The law of conservation of momentum

Total momentum before collision = Total momentum after collision

mu+m'u' = V(m+m')............... Equation 1

Where m = mass of the first freight car, m' = mass of the second freight car, u = initial velocity of the first freight car, u' = initial velocity of the second freight car, V = final combined velocity/ speed.

make V the subject of the equation

V = (mu+m'u')/(m+m')........... Equation 2

From the question,

Given: m = 1234 kg, m' = 2468 kg, u = 6 m/s, u' = 0 m/s (at rest)

Substitute these values into equation 2

V = [(1234×6)+(2468×0)]/(1234+2468)

V = 7404/3702

V = 2 m/s
