Answer:400m
Explanation: x=20⋅10+ 4.10^2/2 =400m
In an atom, you have three particles: protons, electrons, and neutrons.
When you add or subtract electrons from an atom, it means that there are either more protons than electrons (positively charged) or there are more electrons than protons (negatively charged).
You cannot add or subtract protons since they are the atomic number, which means the number of protons determines the element. Neutrons have a neutral charge, so they wouldn't affect the charge at all.
Answer:
answer is (c) density is not a characteristics of vibration.
hope it is right answer for it!!
Yes. A roulette ball circulating in a spinning wheel, a car going around a curved
road at 30 mph, and a planet in a circular orbit are all being accelerated.
"Acceleration" does NOT mean "speeding up". It means any change in the
speed or DIRECTION of motion.
