A
Explanation:
neutrons have neutral charge, while electrons are outside the nucleus with a negative charge
Any unit of acceleration must have the dimensions (form) of
(a unit of length) / (a unit of time)²
Answer:
b
Explanation:
it loses energy due to friction because if it hits objects the objects slow it down and which causes it to start slowing down
This molecule is formed between a not very electronegative metal and a very electronegative nonmetal which means it should be an ionic compound which would mean that it would have the name of potassium oxide.
look up the naming rules for ionic compounds. I would explain it here but I don't know how to explain naming the anion part of the molecule other than it ends in ide since it is a monoatomic anion which is why oxide is in the name instead of oxygen.
I hope this helps. Let me know if anything is unclear or needs more explanation.
Answer:
Correct answer : v = 50 m/s
Explanation:
The movement described is a free fall with no initial velocity and we will use the following formula:
v = g · t we take that g = 10 m/s²
v = 10 m/s²· 5 s = 50 m/s
v = 50 m/s
