$\mathbf x\times\mathbf y=\begin{vmatrix}\mathbf i&\mathbf j&\mathbf k\\4&-5&3\\-2&3&-1\end{vmatrix}$
$\mathbf x\times\mathbf y=\begin{vmatrix}-5&3\\3&-1\end{vmatrix}\mathbf i-\begin{vmatrix}4&3\\-2&-1\end{vmatrix}\mathbf j+\begin{vmatrix}4&-5\\-2&3\end{vmatrix}\mathbf k$
$\mathbf x\times\mathbf y=-4\,\mathbf i-2\,\mathbf j+2\,\mathbf k$

When two straight lines or rays intersect at a shared endpoint, an angle is generated. The correct option is A.

<h3>What is an angle?</h3>

When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."

The diagram for the given problem can be made as shown below. Therefore, the other name for angle 2 will be ∠DGE.

Hence, the correct option is A.

What is the ratio of the intensities of an earthquake PP wave passing through the Earth and detected at two points 19 kmkm and 4

Tamiku [17]

Answer:

The ratio of the intensities is roughly 6:1.

Step-by-step explanation:

The intensity I() of an earthquake wave is given by:

$I = \frac{P}{4\pi d^{2}}$

where P: is the power ans d: is the distance.

Hence, the ratio of the intensities of an earthquake wave passing through the Earth and detected at two points 19 km and 46 km from the source is:

$\frac{I_{1}}{I_{2}} = \frac{P/4\pi d_{1}^{2}}{P/4\pi d_{2}^{2}}$
