The earth is instantly replaced in its orbit by a speck of dust. which statement best describes the subsequent orbital motion of that piece of dust? the earth is instantly replaced in its orbit by a speck of dust. which statement best describes the subsequent orbital motion of that piece of dust? the dust particle will continue in the same orbit as the earth did, orbiting the sun in 1 year. the dust particle will move to a smaller orbit and orbit the sun in less than 1 year. the dust particle will move to a larger orbit and orbit the sun in more than 1 year. the dust particle will spiral into the sun. the dust particle will be ejected from the solar system.

With i really need the correct answer!

Explain why you think this diagram shows what happened to the carbon in the biodome.

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
