Hi, what is the difference between Elliptic and ecliptic? Thanks

Sladkaya [172]

Answer:

An ecliptic is the trajectory drawn by the race of the Sun on the celestial vault. This is the geocentric point of view, seen from the Earth.

An eclipse occurs when the Moon passes through this plane (in two points, called nodes), precisely at the time of the New Moon or Full Moon. The Sun, the Earth and our satellite are then aligned. In the first case, it will be a solar eclipse (the Moon is between the Earth and the Sun). In the second, it will be a lunar eclipse

Write 23,665,700 in Scientific Notation with 4 significant figures.

Aloiza [94]

<u>Answer:</u> The given number in scientific notation is $2.367\times 10^{7}$

<u>Explanation:</u>

Scientific notation is the notation where a number is expressed in the decimal form. This means that the number is always written in the power of 10 form. The numerical digit lies between 0.1.... to 9.9.....

If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.

We are given:

A number having value = 23,665,700

Converting this into scientific notation, we get:

As, the decimal is shifting to left side, the power of 10 will be positive.

$\Rightarrow 23,665,700=2.367\times 10^{7}$

Hence, the given number in scientific notation is $2.367\times 10^{7}$
