An ellipse has two focal points. One of the focal points is the <u><em>Sun</em></u>.
Because they planets move faster when they are around the sun.
Answer:
Option B
Explanation:
I did a question like this a long time ago so i'm not sure if its right so sorry if its wrong
B. When the ball is rolling across the floor at a constant velocity, the change in its kinetic energy is zero.
<h3>
What is change in kinetic energy?</h3>
The change in kinetic energy of an object is the dereference between the final kinetic energy and the initial kinetic energy.
ΔK.E = K.Ef - K.Ei
ΔK.E = 0.5m(vf² - vi²)
where;
- K.Ef is the final kinetic energy
- K.Ei is the initial kinetic energy
- vf is final velocity
- vi is initial velocity
At constant velocity, the initial velocity and final velocity are equal.
ΔK.E = 0.5m(0) = 0
Thus, when the ball is rolling across the floor at a constant velocity, the change in its kinetic energy is zero.

A = distance traveled by steve in north direction by train = 30 miles
B = distance traveled by steve in east direction by train = 25 miles
R = resultant displacement of the steve relative to starting position
using pythagorean theorem
R = √(A² + B²)
inserting the values
R = √(30² + 25²)
R = 39.05 miles
direction : tan⁻¹(B/A) = tan⁻¹(25/30) = 39.8 deg east of north
