Answer:
D) 8
Explanation:
Due to the octet rule the most stable atoms will have 8 valence electrons.
Answer:
The acceleration of the ball as it rises to the top of its arc equals 9.807 meters per square second.
Explanation:
Let suppose that maximum height of the arc is so small in comparison with the radius of the Earth.
Since the ball is launched upwards, then the ball experiments a free-fall motion, that is, an uniform accelerated motion in which the element is accelerated by gravity. Then, the acceleration experimented by the motion remains constant at every instant and position.
Besides, the gravitational acceleration in the Earth and, in consequence, the acceleration of the ball as it rises to the top of its arc equals 9.807 meters per square second.

Answer:
N = 3600 N
Explanation:
centripetal acceleration requirement is
ac = v²/r = 20²/50 = 8 m/s²
As the only available acceleration is gravity, centripetal acceleration must come from that,
This makes the "weight" that the road senses and must counteract
N = m(g - ac)
N = 2000(9.8 - 8)
N = 3600 N
