Answer:
The track of the Moon's shadow across Earth's surface is called the Path of Totality. This path is typically 16,000 kilometers (about 10,000 miles) long but only 160 kilometers (100 miles) or so wide. In order to see the Sun totally eclipsed by the Moon you must be in the path of totality.

Explanation:
10^-8
- Hope that helps! Please let me know if you need further explanation.
Try a different combination.
A^3+ and B^1-, to get a 3- charge you need 3xB^1-, so the formula is AB3.
or
A^3+ and C^2-, you have to get to 6+ and 6-, meaning you need 2xA and 3XC, or A2C3.
Answer:
1.52
Explanation:
speed of light through clear rock salt = speed of light in air (vacuum)/index of refraction
index of refraction of clear rock salt = speed of light in air (vacuum) / speed of light through clear rock salt
index of refraction of clear rock salt= 3.00 x 10^8 m/s / 1.98 × 10^8 m/s
index of refraction of clear rock salt= 3.00 x 10^8/1.98 × 10^8 ( the × 10^8 cancels out)
index of refraction of clear rock salt= 3.00/1.98
index of refraction of clear rock salt= 1.52
