Answer:
B. 25 m/s/s
Explanation:
Centripetal acceleration is the square of the tangential velocity divided by the radius of curvature.
a = v² / r
Given v = 10 m/s and r = 4 m:
a = (10 m/s)² / 4 m
a = 25 m/s²
Atomic number is equal to the number of protons and electrons
Atomic mass - protons = neutrons
protons + neutrons = atomic mass
I hope this helps
Gold’s molar mass is about 196 while aluminum is about 27, thus 50cm of gold has more mass
