Answer:

C

Explanation:

Its C, because all the other planets have A, B, and D. But since earth is just far enough from the sun, it can support life. I think its called liek the perfect area section. Also, mars is too far, venus is the hottest planet, and mercury doesn't even have an atmosphere. im not going to go farther from the astroid belt.

Elena L [17]

Answer:

The ocean is 6485.6m deep when measured from the vessel

Explanation:

v=1474m/s

t=8.88s

let d represent distance from the vessel to the ocean bottom.

an echo travels a distance equivalent to 2d, that is to and fro after it reflects from the obstacle.

velocity=\frac{distance}{time}\\ v=\frac{2d}{t} \\vt=2d\\d=\frac{vt}{2}

d=\frac{1474*8.8}{2}

d= 6485.6m

Light in vacuum is incident on the surface of a slab of transparent material. In the vacuum the beam makes an angle of 39.9° wit
wariber [46]

Answer:

n=2.053

Explanation:

We will use Snell's Law defined as:

n_{1}*Sin\theta_{1}=n_{2}*Sin\theta_{2}

Where n values are indexes of refraction and \theta values are the angles in each medium. For vacuum, the index of refraction in n=1. With this we have enough information to state:

1*Sin(39.9)=n_{2}*Sin(18.2)

Solving for n_{2} yields:

n_{2}=\frac{Sin(39.9)}{Sin(18.2)}=2.053

Remember to use degrees for trigonometric functions instead of radians!

How the movement of the earth cause the appeared daily and annual movement of the sun and stars​
timurjin [86]
As the Earth rotates on it’s axis we perceive the sky differently depending on where we are. This is known as a day, where the Earths rotation controls the day/night cycle. As Earth orbits the sun our axis wobbles, thus at different times in the year different regions of the Earth can see different areas in the sky.

Hope this helps!

¿Porque los sensores son importantes en nuestra vida diaria?
7nadin3 [17]
En la medicina y la biotecnología, los sensores son herramientas que detectan procesos biológicos, químicos, o físicos y luego transmiten o reportan esta información. Algunos sensores trabajan fuera del cuerpo, mientras que otros están diseñados para ser implantados dentro del cuerpo.

Algunos dispositivos de monitoreo constan de múltiples sensores que miden una serie de parámetros físicos o biológicos. Otros dispositivos pueden ser multifuncionales, incorporando sensores y luego suministrando un fármaco o intervención en base a la información obtenida de los sensores. Los sensores pueden ser también componentes en sistemas que procesan muestras clínicas, tales como los dispositivos cada vez más comunes conocidos como “lab-on-a-chip”.

Los sensores ayudan a los proveedores del cuidado de la salud y a los pacientes a monitorear las condiciones de la salud y asegurar que puedan tomar decisiones informadas sobre el tratamiento. Los sensores también se utilizan a menudo para monitorear la seguridad de los medicamentos, los alimentos, las condiciones ambientales, y otras sustancias que podríamos encontrar.
