Answer:

930,000

Explanation:

9.3 x 10^5

The power of 10 (5 in this question) gives the number of times the decimal point is to be moved to the right.

If there was a negative sign in front of the power, the number would have been an indication of how many times the decimal point is to be moved to the left.

Further to this

9.3 x 10^5 = 9.30000000 x 10^5

= 930000.000

= 930,000

The speed of light in cubic zirconia

schepotkina [342]

The index of refraction for the cubic zirconia at the given speed of light is 2.16.

The given parameters:

Speed of light in Cubic zirconia, v = 1.39 x 10⁸ m/s
Speed of light in air, c = 3.0 x 10⁸ m/s.

The index of refraction for the cubic zirconia is the ratio of the speed of light in air to speed of light in cubic zirconia and it is calculated as follows;

$\eta = \frac{c}{v} \\\\\eta = \frac{3\times 10^8}{1.39 \times 10^8} \\\\\eta = 2.16$

Thus, the index of refraction for the cubic zirconia at the given speed of light is 2.16.

After a light turns green , Lesly accelerates to 120 km/hr over 100 meters . What is her acceleration in m/s^2

Ivenika [448]

Answer:

5.55 m/s²

Explanation:

Initial velocity = 0
Final velocity = 120 km/hr = 33.3 m/s
Displacement = 100 m

Using Third law of Motion :-

$\longrightarrow$ 2as = v² - u²

$\longrightarrow$ 2*a* 100 = (33.33 m/s)²-0²

$\longrightarrow$ a = 200a = 1110.89

$\longrightarrow$ a = 1110.89/200

$\longrightarrow$ a = 5.55 m/s²

Symbols have their usual meaning .
