Why isn’t pluto currently considered a planet?

a. pluto’s orbit around the sun is larger than that of any of the eight planets.

b. pluto is smaller than all of the eight planets.

c. pluto has a moon, charon, which is more than half its size and larger than other planets’ moons.

d. pluto’s gravity is too weak to pull in smaller debris, so it hasn’t cleared its orbital path.

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

Properties seen when one one substance changes to another are known as properties

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
