1 answer:
Using Kepler's third law, the average sun -Vesta distance is 2.36 AU.
According to Kepler's laws, the square of the period of revolution of planets are proportional to the cube of their average distances from the sun. Hence, we can write;
Where;
T = period of the planet
r = average distance of the planet
When;
T = 3.63 years
r =
r =
r = 2.36 AU

Answer:
7.9
Explanation:
When we put the metal piece in the liquid (which is in the graduated cylinder), how much it goes up is equal to the volume of the piece we inserted.
So now we know that the volume of that piece of unknown metal is 7mL (which is the same as 7).
Density is .
So the density of that piece of metal is
Which leaves us with a final density of 7.9
