Answer:b speed with displacement
Explanation:
The statement is true because an object will remain not moving until an external force is applied into. so in order to move an object external force should be applied. for example an object fell down, even no one pushes it pulls it, but the force due to gravity is acting on it so there is still a force acting on it.
<span>So we want to know what is not influencing the phases of the Moon. What influences Moon phases are celestial bodies that are close enough to have enough gravitational force to have an influence. Those celestial bodies would be the Earth and the Sun, since moon itself cant influence itself and all other stars are too far to exert gravitational force. So the correct answer would be the Moon and the stars do NOT have an influence on the Moon phases. </span>
Answer:
The eccentricity of an elliptical orbit is defined by the ratio e = c/a, where c is the distance from the center of the ellipse to either focus. The range for eccentricity is 0 ≤ e < 1 for an ellipse; the circle is a special case with e = 0.
Explanation:
Answer:
20meter/second
Explanation:
v=squareroot of 2×K.E/mass
v=squareroot of 2×100J/0.5
v=squareroot of 200kg×m×m/s×s/0.5m
v=squareroot of 400m×m/s×s
v=20m/s
