I think the answer is 7mm but I'm not sure.
Have a great day!
Answer:
D) forms hydronium ions in water
Explanation:
Texture and conductivity are physical properties which makes answer A and B wrong. Answer C does not refer to a chemical reaction.
Answer: -
The acceleration due to gravity at height r = a = GM/r²
Rearranging
r² = GM /a
= (6.674 x 10⁻¹¹ x 5.972 x 10²⁴ ) / 5
r = 8.917 x 10⁶ m
r = 8917 Km
Now Radius of earth = 6371 Km
So height = 8917 - 6371 = 2546 Km
1.) protons neutrons and electrons
2.) a wall outlet it is made up of metal that conducts heat. When when heat is applied it provides enough energy to these electrons
3.) is an imbalance if electric charges within or on the surface of a material
4.) static electricity decoded tiny changes in the surface of a balloon causes it to charge more when rubbed against our hair
5.) you might have to answer that on your own but if you don’t want to here’s my experience
One day me and my twin brother were jumping on the trampoline and when we fell down my hair rubbed against the surface of it and stuck up
Hope that helped and Brainiest?
