Corrosion is the irreversible damage or destruction of living tissue or material due to a chemical or electrochemical reaction.
If you mean work out as in using calculations, I don't know how to help you. But there is a way to find out, using Fleming's left hand rule. I can't define it properly, and I don't want to copy-paste from another site, so I strongly recommend that you look it up. Try google, or more specific, BBC GCSE bitesize.
Hope this helps!
The resultant force on the system is equivalent to the difference in the weights of the chandelier and Robin Hood.
F(net) = 240g - 85g
F(net) = 155g
Robin Hood's Acceleration:
F = ma
155g = 85a
a = 17.89 m/s²
Tension = mg + ma
Tension = 85(g + a)
Tension = 2400 N
Answer:
C the baseball began at rest and rolls at a rate of 14.7 m/s after 1.5 seconds
