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.

Gas cloud 1 is likely to form a star. gas cloud 2 is not. based on this information, match the given conditions with each cloud

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

Acaterpillar tries to climb straight up a wall a meter high, but for every 2 cm up it climbs, it slides down 1 cm. eventually, it reaches the top. when it reaches the top, it does not pull itself over so it will slide down 1 cm. what is the total displacement traveled?
