Light travels at 300,000 km per second. Mars is 56 million km away from Earth. How many seconds does it take light to travel fro
alina1380 [7]

Answer:

<em> It takes 186.67 second for the light to travel from Mars to earth.</em>

Explanation:

Light: Light is a visible form of energy which is radiated outward from a source. Light travels in a straight line, and this phenomenon is called rectilinear propagation of light.

S = d/t .......................... Equation 1

making t the subject of the equation

t = d/S ......................... Equation 2

Where S = speed of light, d = distance between the earth and Mars, t = time

<em>Given: d = 56000000 km, S = 300000 km per seconds.</em>

<em>Substituting these values into equation 2</em>

<em>t = 56000000/300000</em>

<em>t = 186.67 seconds.</em>

<em>Thus it takes 186.67 second for the light to travel from Mars to earth.</em>

The magnitude​ R, measured on the Richter​ scale, of an earthquake of intensity I is defined as Requalslog StartFraction Upper I
lapo4ka [179]

Answer:

R = 6.8

Explanation:

Given data:

Richter scaleR = log(\frac{I}{I_o})

where R - magnitude of earthquake of Richter scale

I - quake's intensity =  10^{6.8} \times I_o

I_o - minimum intensity earthquake

Plugging all information in the equation to get Richter's scale

R = log(\frac{10^{6.8} \times I_o}{I_o})

R = log(10^{6.8})

R = 6.8
