When a honeybee flies through the air, it develops a charge of +20 pC . Part A How many electrons did it lose in the process of

Yuri [45]

Answer:

1.3 × 10⁸ e⁻

Explanation:

When a honeybee flies through the air, it develops a charge of +20 pC = + 20 × 10⁻¹² C. This is a consequence of losing electrons (negative charges). The charge of 1 mole of electrons is 96468 C (Faraday's constant). The moles of electrons representing 20 pC are:

20 × 10⁻¹² C × (1 mol e⁻/ 96468 C) = 2.1 × 10⁻¹⁶ mol e⁻

1 mole of electrons has 6.02 × 10²³ electrons (Avogadro's number). The electrons is 2.1 × 10⁻¹⁶ moles of electrons are:

2.1 × 10⁻¹⁶ mol e⁻ × (6.02 × 10²³ e⁻/ 1 mol e⁻) = 1.3 × 10⁸ e⁻

A cube that has a volume of 1.00 m³ contains N distinguishable particles.

grandymaker [24]

Answer:

1 P = 0.5

2 P = 0.3

3 P = 0.01

Explanation:

The probability formula is

$P =V^N$

Where P is the probability V is the volume while N is the number of distinguishing particles

So for N = 1 and $V = 0.500m^3$

$P = (0.500m^3)^1\\$

= 0.5

For N = 1 and $V = 0.300m^3$

$P = (0.300m^3)^1$

= 0.3

For N = 1 and $V = 0.0100m^3$

$P =(0.0100m^3)^1$

= 0.01
