That ratio is 2 .
<h3>What is ratio?</h3>
A ratio is the comparison of the two numbers bydivision.
Taking the first two outputs, or the -1/8 and -1/4, we can divide not the second one by the first one to find the
ratio:
-1/4-1/8
When dividing fractions, we multiply by the reciprocal:
-1/4x-8/1
To multiply fractions, multiply straight across:
(-1x-8)/(4x1) 8/4=2

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>
Answer:
The maximum speed of car will be 20.5m/sec
Explanation:
We have given mass of car = 1100 kg
Radius of curve = 82.3 m
Static friction 
We have to find the maximum speed of car
We know that at maximum speed centripetal force will be equal to frictional force 
So the maximum speed of car will be 20.5m/sec
'Newton' is [ kg·m/s² ].
So if you divide Newtons by [ m/s ], it goes something like this:
(kg·m/s²) / (m/s) =
(kg·m/s²) · (s/m) =
(kg·m·s / m·s²) =
kilogram / second .
This is an interesting exercise in manipulating units, but it doesn't seem to mean anything in the real world.
We performed one meaningless operation ... dividing force by speed ... and ended up with another quantity that has no physical significance ... kilogram per second.
