Physics
1 answer:
anzhelika [568]3 years ago
3 0

Answer:

1⁺ ion

Explanation:

Metals in the first group on the periodic table will prefer to form 1⁺ ion. This is because the 1 valence electron in their orbital.

Most metals are electropositive and would prefer to lose electrons than to gain it.

Like all metals, the group 1 elements called the alkali metals would prefer to lose and electron.

On losing an electron the number of protons is then greater than the number of electrons. This leaves a net positive charge.

A descent vehicle landing on the moon has a vertical velocity toward the surface of the moon of 36.5 m/s. At the same time, it h
sammy [17]

Answer:

66.26 m/s

Explanation:

Horizontal velocity, Vx = 55.3 m/s

Vertical velocity, Vy = 36.5 m/s

The value of the resultant velocity is given by the vector sum of the two velocities which are acting at 90°.

V=\sqrt{V_{x}^{2}+V_{y^{2}}}

V=\sqrt{55.3^{2}+36.5^{2}}}

V = 66.26 m/s

Thus, the velocity of the vehicle is 66.26 m/s along its descent path.

A beam of light passes through a liquid into air. Angle 1, angle of
Ede4ka [16]

Answer: 1.57

Explanation:

This described situation is known as Refraction, a phenomenon in which light bends or changes its direction when passing through a medium with a index of refraction different from the other medium.  

In this context, the index of refraction is a number that describes how fast light propagates through a medium or material.  

According to Snell’s Law:  

n_{1}sin(\theta_{1})=n_{2}sin(\theta_{2}) (1)  

Where:  

n_{1} is the first medium index of refraction (the value we want to know)

n_{2}=1 is the second medium index of refraction (air)  

\theta_{1}=23\° is the angle of incidence

\theta_{2}=38\° is the angle of refraction

Now, let's find n_{1} from (1):

n_{1}=n_{2}\frac{sin \theta_{2}}{sin \theta_{1}} (2)  

Substituting the known values:

n_{1}=1\frac{sin(38\°)}{sin(23\°)}  

Finally:

n_{1}=1.57
