Lightning occurs when there is a flow of electric charge (principally electrons) between the ground and a thundercloud. The maxi

V125BC [204]

Answer:

$1.25\times 10^{19}\ electrons$

Explanation:

r = Rate of flow of charge = 20000 C/s

t = Time taken = 100 μS

Charge is given by

$Q=rt\\\Rightarrow Q=20000\times 100\times 10^{-6}\\\Rightarrow Q=2\ C$

The charge that flows between the ground and the cloud in this time is 2 C

Number of electrons is given by

$n_e=\dfrac{Q}{e}\\\Rightarrow n_e=\dfrac{2}{1.6\times 10^{-19}}\\\Rightarrow n_e=1.25\times 10^{19}\ electrons$

The number of electrons is $1.25\times 10^{19}\ electrons$

The repulsive force between two protons has a magnitude of 2.00 N. What is the distance between them?

Aloiza [94]

Answer:

The answer to your question is letter A. r = 1.07 x 10⁻¹⁴ m

Explanation:

Data

F = 2 N

d = ?

q = 1.6 x 10 ⁻¹⁹ C

k = 8.987 Nm²/C²

Formula

$F = K\frac{q1q2}{r^{2}}$

Solve for r

$r = \sqrt{\frac{kq1q2}{F}}$

Substitution

$r = \sqrt{\frac{8.987 x 10^{9}x1.6 x 10^{-19} x 1.6 x 10x^{-19}}{2}}$

Simplification

r = $\sqrt{\frac{2.3 x 10^{-28}}{2}}$

r = $\sqrt{1.15 x 10^{-24}}$

Result

r = 1.07 x 10⁻¹⁴ m

A shell of mass m and speed v explodes into two identical fragments. If the shell was moving horizontally (the positive x direct

-Dominant- [34]

Answer:

The velocity of the other fragment immediately following the explosion is v .

Explanation:

Given :

Mass of original shell , m .

Velocity of shell , + v .

Now , the particle explodes into two half parts , i.e $\dfrac{m}{2}$ .

Since , no eternal force is applied in the particle .

Therefore , its momentum will be conserved .

So , Final momentum = Initial momentum

$mv=\dfrac{mv}{2}+\dfrac{mu}{2}\\\\u=v$

The velocity of the other fragment immediately following the explosion is v .
