The farther from the sun an object is the larger the distance a planet has to orbit the sun. So if a planet is far from the sun the years would be longer. And if a planet is close to the sun it would be much hotter than a planet that is far from the sun.
Answer: A: false
Explanation:
And object will weigh less on the moon because the moons gravity is weaker than Earths gravity.
The answer would be:
B. Chlorine, iodine and Fluorine
Barium has 2 valence electrons. To satisfy the BaX₂ , this would mean that Barium will need to give one of each of its electrons. The elements that need 1 electron would be those that have 7 valence electrons to complete the octet. These elements would fall in group 7 or halogens. Chlorine, iodine and fluorine are all in Group 7, so this would be the best choice.
Work = (force) x (distance)
80 J = (force) x (4 m)
Force = (80 J) / (4 m) = 20 N
That's IF the force was in the same direction as the 4m of motion.
If the force was kind of slanted, then it had to be stronger, and
it had a component of 20N in the direction of the motion.
