Answer : The most likely charge of an ion formed from an atom will be, (-1) charge.

Explanation :

The given electronic configuration is,

$1s^22s^22p^5$

The number of electrons = 2 + 2 + 5 = 9 electrons

An element is, Florine (F)

For attaining the stable electronic configuration, we need one more electron. When we are adding an electron in the given electronic configuration then it will be negatively charged (-1).

The stable electronic configuration will be,

$1s^22s^22p^6$

The element Florine will be an anion and have negative charge, $F^-$

Hence, the most likely charge of an ion formed from an atom will be, (-1) charge.

It will be -1 because in valence shell there will be 7 electrons so it will take 1 from other atom to complete its outer shell

A water gun fires 5 squirts per second. The speed of the squirts is 15 m/s.

stira [4]

Answer: 3.75 m

Explanation:

5 squirts in 1 second

So, 1 squirt in 1/5 second which is 0.2 second.

The difference in timing of two consecutive squirt is 0.2 second, so

time (t) = 0.2 s.

speed (s) = 15 m/s

Distance of separation (d) = ?

Now, formula for distance is

d = s × t

d = 15 × 0.2

d = 3.75 m

A plane passes over Point A with a velocity of 8000 m/s north. Forty seconds later it passes over Point B at a velocity of 10,00

Airida [17]

Answer:

The planes’ acceleration from A to B is 500m/s^2

Explanation:

Given that the initial velocity u is 8000m/s

and also given the final velocity v=10,000 m/s

the time taken to move from A to B = 40 second

The acceleration is defined as the rate of change of velocity with time

we know that the expression for acceleration is given as

a=(v-u)/t

substituting our given data into the expression for a we have

a=(10000-8000)/40

a=2000/40

a=500m/s^2

The planes’ acceleration from A to B is 500m/s^2

A car is driving along a road at a speed of 50 km/hr. How far will the car travel in 5 hours?

BARSIC [14]

Answer:

I think it's 250

Explanation:

If the car is traveling 50 km/hr that means every hour, the car drives 50 km. So if you want to know how far it will go in 5 hours you do 50x5.

a nitrogen laser generates a pulse containing 10.0 mj of energy at a wavelength of 340.0 nm. how many photons are in the pulse?

Wewaii [24]

A nitrogen laser generates a pulse containing 10.0 mj of energy at a wavelength of 340.0 nm and has 1785 x 10¹⁹ photons in the pulse.

<h3>How many photons are in the pulse?</h3>

Energy of a single photon is

E=hcλ

E=6.626×10⁻³⁴ J s×3×108 m/s /340×10⁻⁹ m

E=6.31×10⁻¹⁹ J

Number of photons in the laser is

n=Total Energy/Energy per photon

n=10⁷×10⁻³J /5.90×10⁻¹⁹J/photon

n= 1785 x 10¹⁹ photons
