Answer:
3.2 miles
Explanation:
We can assume that the light coming from the lightning reach instantaneously our eyes (because light travels very fast, 
), so the time between the lightining and the hearing of the thunder is equal to the time that sound takes to each us.
Sound travels in air approximately at speed
v = 343 m/s
So the distance it covers in a time of t = 15 seconds is
And using the conversion from meters to miles,
1 mile = 1609 meters
we find
Answer:
All of these
Explanation:
Mantle convection causes tectonic plates to move around and passes heat on the earth surface in forms of lava and magma.

When an object is moving with uniform circular motion, the centripetal acceleration of the object d. is directed toward the center of motion.
Mass will remain constant on both planet, let mass of the object be "m".
let x be the <span>acceleration due to gravity on the surface of mars.
Weight of object on earth = m *g , where g is </span><span>acceleration due to gravity on the surface of earth
</span>⇒350 = m * 9.8
⇒m = 350 / 9.8 .............................equation(1)
Weight of object on mars = m * x , where x is acceleration due to gravity on the surface of mars
134 = m * x .............................equation(2)
putting the value of m from equation (1) in equation(2) , we get,
x = (134 * 9.8) / 350
⇒ x = 3.572 m/s²
