Hence, the horizontal velocity of the rover is 1.73 m/s
The are elements on the periodic table
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)
hope it helped.

Answer:
Explanation:
Thermal expansion is where materials expand while being heated, causing them to take up more space. Some materials expand more than others. But this all happens due to the motion of tiny little molecules. Temperature is the average kinetic energy of the molecules in a substance.
Thermal expansion is an important consideration for engineering because different materials exhibit changes in size when exposed to heat. Thus, affecting length, width, surface area, volume, shape etc
Answer:
Explanation:
The frequency of a simple pendulum is given by:
where
g is the acceleration of gravity
L is the length of the pendulum
Calling 
the length of the first pendulum and 
the acceleration of gravity at the location of the first pendulum, the frequency of the first pendulum is
The length of the second pendulum is 0.4 times the length of the first pendulum, so
while the acceleration of gravity experienced by the second pendulum is 0.9 times the acceleration of gravity experienced by the first pendulum, so
So the frequency of the second pendulum is
Therefore the ratio between the two frequencies is
