Answer:
Seven
Explanation:
Because all halogens have seven valence electrons, they are “eager” to gain one more electron. Doing so gives them a full outer energy level, which is the most stable arrangement of electrons. Halogens often combine with alkali metals in group 1 of the periodic table.
Answer:
Halogens only need one electron to complete their valkance shells.
Explanation:
Halogens are present in the VIIA group of the periodic table so seven electrons are already present. one is needed to become stable.
The minimum dimensions for the rear-view mirror should be a height of 0.890 m and a width of 1.3 m.
In order for the driver to be able to see the entire width and height of the rear window in the rear-view mirror without moving their head, the mirror should have minimum dimensions that allow for this visibility. Let's calculate the minimum height and width required for the rear-view mirror.
Height of the mirror:The mirror should be half the height of the driver, which is given as 1.715 m at the top and 0.825 m at the bottom. Therefore, the height of the mirror should be 0.890 m (1.715 m - 0.825 m).Width of the mirror:The mirror should be wide enough to capture the entire width of the rear window. The width of the rear window is given as 1.3 m, so the width of the mirror should be at least 1.3 m. Therefore, the minimum dimensions of the rear-view mirror should be a height of 0.890 m and a width of 1.3 m.#SPJ12
The equator is the closest part of out planet that is closest to the sun, which means that the continents closest to the equator will in turn be warmer.
The imaginary line that circles the Earth's center is known as the Equator. It divides the Earth into the Northern and Southern Hemispheres and is located halfway between the North and South Poles.
An equator is a hypothetical line that circles a planet or other celestial body in the centre. At its Equator, the Earth is at its broadest. The circumference of the Earth, measured at its equator, is 40,075 kilometers (24,901 miles).
The equatorial bulge is a phenomena caused by the Earth's diameter being wider in the Equator. A straight line with its endpoints on the circle's edge and a path through its center is used to calculate a circle's diameter.
Therefore, The equator is the closest part of out planet that is closest to the sun, which means that the continents closest to the equator will in turn be warmer.

The mechanical advantage of a ramp that is 6.0 m long and 1.5 m tall. we can easily take any object to height of 6 m.
Gravitational potential energy is an energy acquired by an object due to a change in its height when it is present in a gravitationalfield. It is denoted by P or U. and it its expressed in joule. Gravitational potential energy is given by U = mgh where m is the mass of the object, g is acceleration due to gravity and h is the height.
when we take an object of mass m to a certain height in the field of gravitation, we can say that body has potential energy and we release that body from that height, it falls.
Ramp of 6.0 m long and 1.5 m tall is that there will be angle made by the inclination is 14.4°. Mechanical advantage of a ramp is, it is used for transportation of heavy objects to a certain height at certain distance. It reduces physical efforts and make our task faster. when we have to transport lots of object to a certain height, when we put objects on the ramp which has motor and upper part of the belt rotates, it will easily get transported to that height without physical efforts. Escalator is also a type ramp. Ramp which has no rotator, we have to push objects on the ramp to that height.
Hence these are advantages of a ramp.
