Answer:

The answer is: The Grand Canyon is a testament to the erosive power of water. This modified model seems to be the predominant theory among today's evolutionary geologists.

Explanation:

The Grand Canyon is one of the most impressive erosive features in the world.

Carved through sedimentary layers of sandstone, limestone and shale and in the basement formations of mostly metamorphic shales and igneous granites, the Grand Canyon is a testament to the erosive power of water.

The now widely accepted theory has the capture of the current that takes place in one of the northwest drains that is believed to have existed before the elevation of the plateau.

It was believed that the ancestral Colorado River had turned north, draining into the Great Salt Lake region.

Once again, once the capture was carried out, the plateau rose, which caused the drains that tend to the northwest to flow into the Colorado River.

This modified model seems to be the predominant theory among today's evolutionary geologists.

balu736 [363]

Answer:

FB = 0.187 N

Explanation:

To find the magnetic force FB in the wire you use the following formula:

$|\vec{F_B}|=ILBsin\theta\\\\L=0.25m\\\\|\vec{B}|=\sqrt{(0.3y)^2+(0.4y)^2}=0.5y \ T$

the angle between B and L is given by:

$\vec{L}\cdot\vec{B}=LBcos\theta\\\\\theta=cos^{-1}(\frac{\vec{L}\cdot\vec{B}}{LB})=cos^{-1}(\frac{0*0.3y+0.25*0.4y}{0.25*0.5y})=36.86\°$

Due to B depends on "y" you take into account the contribution of each element dy of the wire to the magnitude of the magnetic force. Thus, you have to integrate the following expression:

$|\vec{F_B}|=Isin\theta\int_0^{0.25}B(y)dy=Isin\theta\int_0^{0.25}(0.5y)dy\\\\|\vec{F_B}|=(2.0*10^{-3}A)(sin36.86\°)(0.5T)[\frac{0.25^2}{2}m]=0.187\ N$

hence, the magnitude of the magnetic force is 0.187N

¿Cuál de las siguientes magnitudes es derivada?

Sedaia [141]

Answer:

A. El volumen

B. La densidad.

Explanation:

A derived quantity is defined as one that has to be calculated by using two or more other measurements.

Volume is a derived quantity because it requires one to use different measurements to determine it. For instance, in the case of a cube, the length, width and height of the cube are all needed to calculate volume.

Density is also a derived quantity because it needs both volume and mass for it to be calculated.
