Option (c) is the correct answer. Halogens react by gaining one electron.

The halogens in the periodic table are Florine, chlorine, Bromine, iodine, astatine

All these electrons are short of one electron in the outermost shell. so these halogens gain one electrons and form anions.

For example, Florine has an atomic number of 9. so its electronic configuration is given by 2,7. it needs one electron to complete its octet as

F + e--------> F⁻

All other halogens similarly gain one electron to react.

Each lunar cycle has one full moon, in which the relative positions of Earth, the sun, and the moon form in a straight line
aniked [119]

Complete Question:

Each lunar cycle has one full moon, in which the relative positions of Earth, the sun, and the moon form in a straight line. Which list represents the position of Earth, the sun, and the moon during a full moon?

Group of answer choices.

A. Earth, sun, moon

B. sun, moon, Earth

C. moon, sun, Earth

D. sun, Earth, moon

Answer:

D. sun, Earth, moon

Explanation:

A lunar eclipse is a phenomenon that occurs when the Earth comes between the Moon and the Sun thereby causing it to cover the Moon with its shadow.

Simply stated, lunar eclipse takes place when the Moon passes or moves through the Earth's shadow thereby blocking any ray of sunlight from reaching the Moon. Thus, the full moon appears deep red (blood moon).

Also, a lunar eclipse would occur only when the Sun, Earth, and Moon are closely aligned to form a straight line known as the syzygy.

There are three (3) types of lunar eclipse and these are;

1. Total lunar eclipse.

2. Partial lunar eclipse.

3. Penumbra lunar eclipse.

Each lunar cycle has one full moon, in which the relative positions of Earth, the sun, and the moon form in a straight line. Thus, the list which represents the position of Earth, the sun, and the moon during a full moon is sun, Earth, and moon

A skateboarder jumps horizontally off the top of a staircase and lands at bottom of the stairs. The staircase has a horizontal l
e-lub [12.9K]

Answer:

The vertical velocity of the skater upon landing is 10.788 meters per second.

Explanation:

Skateboarder experiments a parabolic movement. As skateboarder jumps horizontally off the top of the staircase, it means that vertical component of initial velocity is zero and accelerates by gravity, the final vertical speed is calculated by the following expression:

v = v_{o} + g\cdot t

Where:

v_{o} - Initial vertical speed, measured in meters per second.

v - Final vertical speed, measured in meters per second.

g - Gravitational acceleration, measured in meters per square second.

t - Time, measured in seconds.

Given that v_{o} = 0\,\frac{m}{s}, g = -9.807\,\frac{m}{s^{2}} and t = 1.10\,s, the final velocity of the skater upon landing is:

v = 0\,\frac{m}{s} + \left(-9.807\,\frac{m}{s^{2}} \right)\cdot (1.10\,s)

v = -10.788\,\frac{m}{s}

The vertical velocity of the skater upon landing is 10.788 meters per second.
