In a Hydrogen molecule there are a total of four charges, 2 protons in the two nuclei, and 2 electrons. How many unique charge-p
lutik1710 [3]

Answer:

The total number of charge pair without double counting is 6.

Explanation:

Given that,

Number of proton = 2

Number of electron = 2

We need to calculate the total number of charges in Hydrogen atom

Using formula for number of charges

n= p+n

n =2+2

n=4

Number of charge in pair is

r = 2

We need to calculate the total number of possible combination of pairs without double counting

Using formula of combination

N=_{n}C^{r}

Where, n = number of charges

r = number of charges per pair

Put the value into the formula

N=_{4}C^{2}

N=\dfrac{4\times3\times 2}{2(4-2)}

N=\dfrac{4\times3\times 2}{2\times2}

N=6

Hence, The total number of charge pair without double counting is 6.

A 4-kilogram ball moving at 8 m/sec to the right collides with a 1-kilogram ball at rest. After the collision,
elena-14-01-66 [18.8K]
Conservation of momentum: total momentum before = total momentum after

Momentum = mass x velocity

So before the collision:
4kg x 8m/s = 32
1kg x 0m/s = 0
32+0=32

Therefore after the collision
4kg x 4.8m/s = 19.2
1kg x βm/s = β
19.2 + β = 32

Therefore β = 12.8 m/s
