A stealth bomber is moving at 799km/h west and travels to a top velocity of 1,1325km/h west in 4.8 minutes.
maria [59]

Answer:

10.1 ms^-2

Explanation:

From;

v = u + at

v = final velocity

u = initial velocity

a= acceleration

t = time taken

To convert the velocity from Km/hr to m/s we us;

x * 1000/3600

Where x is the velocity in Km/hr

So;

799 * 1000/3600 = 221.9 m/s

11325 * 1000/3600 = 3145.8 m/s

4.8 minutes = 4.8 * 60 = 288 s

Applying the formula;

a= v - u/t

a = 3145.8 - 221.9/288

a = 10.1 ms^-2

Given that nitrogen forms three bonds with hydrogen to make <img src="https://tex.z-dn.net/?f=NH_%7B3%7D" id="TexFormula1" title
lbvjy [14]

Answer:

Three hydrogen atoms to form PH₃.

Explanation:

Hello!

In this case, since the elements belonging to the nitrogen family (N, P, As, Sb and Bi) show five valence electrons, because there are five electrons at their outer shell, it is clear that if phosphorous bonds with hydrogen, it is going to require the same amount of oxygen atoms (3) because elements having five valence electrons need 3 bonds in order to attain the octet (5+3=8).

Therefore the compound would be:

PH_3

Which is phosphine.

Best regards!
