If speed = distance/time , then time = speed/distance.
So...
Speed of light = 3*10^8(m/s)
Average distance from Earth to Sun = 149.6*10^9(m)
Therefore, t=(3*10^8(m/s))/(149.6*10^9(m))
I hope this was a helpful explanation, please reply if you have further questions about the problem.
Good luck!
Answer:
B. speed up
Explanation:
The acceleration of an object due to a body's gravity is:
g = GM / r²
where G is the universal constant of gravitation,
M is the mass of the body,
and r is the distance from the body.
As a planet approaches the sun, r decreases. As r decreases, g increases.
Answer:
The change in volume for a metallic dental filling due to the temperature difference is <u>0.1143 mm</u>.
Explanation:
Given:
Temperature of the body is, 
Temperature of the ice-cream is, 
Initial volume of the filling is, 
Coefficient of thermal expansion is, 
We know that the coefficient of volume expansion is related to thermal expansion as:

Now, change in volume for a metallic dental filling is given as:

Therefore, the change in volume for a metallic dental filling due to the temperature difference is 0.1143 mm.
