Answer:
There is no exception to this. all planets have some eccentricity. it is physically impossible to have an orbit without any eccentricity. However, venus's orbit has the lowest (0.007) eccentricity (closest to circular) so that could be your answer.
Mercury's orbit's eccentricity 0.2
Venus's orbit's eccentricity 0.007 (this is the lowest so it may be your answer)
Earth's orbit's eccentricity 0.0167
Mars's orbit's eccentricity 0.0934
Jupiter's orbit's eccentricity 0.0489
Saturn's orbit's eccentricity 0.0565
Neptune's orbit's eccentricity 0.009
Uranus's (yur,in,iss) orbit's eccentricity 0.0457
Pluto's (not really a planet) orbit's eccentricity 0.2444 (very high)

Answer:The higher up an object is the greater its gravitational potential energy. The larger the distance something falls through the greater the amount of GPE the object loses as it falls. As most of this GPE gets changed into kinetic energy, the higher up the object starts from the faster it will be falling when it hits the ground. So a change in gravitational potential energy depends on the height an object moves through.
Explanation: Lifting an apple up 1 metre is easier work than lifting an apple tree the same height. This is because a tree has more mass, so it needs to be given more gravitational potential energy to reach the same height.
It indicates that car is at rest at all time (t) :-)

Explanation:
mass, m = 5kg
initial velocity, u = 16m/s
final velocuty, v = -22m/s
change in momentum, ∆p = ?
∆p = m (v-u)
5(-22-16)
5(38)
∆p = 190kgm/s
check the calculations!
Answer:
4.23 beats / seconds
Explanation:
Frequency heard = f = f₁ - f₂
f₂ = f₁ √ ( F₂ / F₁)
f = f₁ - f₁ √ ( F₂ / F₁) = f₁ ( 1 - √ ( F₂ / F₁) = 523 Hz ( 1 - 0.9919 ) = 4.23 beats / seconds
