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

damaskus [11]

Given:
The rate of charge flow in the lightning bolt is 24000 C/s = 24×10³ C/s.
Duration of charge flow = 105 μs = 105×10⁻⁶ s

By definition, the current flow is
I = (24×10³)/(105×10⁻⁶) = 2.286×10⁸ A = 228.6 MA (mega amps)

Answer: 228.6 MA

The force of 20\hat{j}~\text{N}20 j ^ N is applied at \vec{r} =(4.0\hat{i}-2.0\hat{j})~\text{m} r ⃗ =(4.0 i ^ −2.

Lostsunrise [7]

Answer:

$-80\hat{k}\text{ N/m}$

Explanation:

Torque is given by

$\tau = \vec{F} \times\vec{r}$

Note that this is a cross product of vectors. To perform a cross product, we need to express the vectors in three components.

$\vec{F} =0.0\hat{i} + 20\hat{j} + 0.0\hat{k}$

$\vec{r} =4.0\hat{i} - 2.0\hat{j} + 0.0\hat{k}$

The torque is then

$\tau = \left|\begin{matrix}\hat{i} & \hat{j} & \hat{k} \\ 0.0 & 20 & 0\\ 4.0 & - 2.0 & 0.0\end{matrix}\right|$

$\tau = -80\hat{k}\text{ N/m}$

(I'm not sure if the matrix will appear well because I'm constrained with the device I'm using but what I'm showing is the determinant of a matrix with i, j, k in the first row, the coefficients of F in the second and the coefficients of r in the third)
