Answer:
In chemistry, a nonmetal is a chemical element that is mechanically weak in its most stable form, brittle if solid, and usually gains or shares electrons in chemical reactions. There is no universal agreement on which elements are nonmetals; the numbers generally range from fourteen to twenty-three, depending on the criterion or criteria of interest.
The atomic number tells you the number of protons in an atom. This value never changes because the number of protons in the nucleus always remains constant. The mass number tells you the number of protons and neutrons (or nucleons) together: protons + neutrons = mass number. Since the number of neutrons in the nucleus varies, you can have different amounts of neutrons in the same type of atom. These varied types are called isotopes.
Hope this helps.
I believe it is call “Acceleration”
Answer:
The fly travels 2.4 m
Explanation:
Since the Two steamrollers begin 100 m apart and head toward each other, each at a constant speed of 1.00 m/s, we can find the time until they crash by the formula:
Distance = Speed × Time
Time = Distance /Speed
Time = (100 m) / (1 m/s)
Time = 100 hours
Now, the fly will spend the same amount of time traveling as the steamrollers.
Since the fly moves at a speed of 2.4 m/s and we have a time of one hour the steamroller take to collide, then the fly will go a distance of;
Distance = speed x time = 2.4 × 1 = 2.4 m
Answer:
answer E
Explanation:
cuz its 45 is divisible by 3 and 5 but not 10
