The second one if it’s on edge
I'm afraid you're not paying attention. This question is loaded with
all the important words, and you don't recognize Newton's second
law of motion. Didn't you notice the "force", "acceleration", and
"mass" all over the place in there ?
Newton's 2nd law: Force = (mass) x (acceleration)
The answer is going to be 'mass', so let's divide
each side of Newton's law by 'acceleration':
Mass = (force) / (acceleration)
Now, just write in the numbers that the question gave you:
force = 60 newtons
acceleration = 4 m/s²
Here's the equation again: Mass = (force) / (acceleration)
= (60 N) / (4 m/s²)
= 15 kg .
Answer: The density is greater at point C
Explanation: At that point
The convention current slowly cools off
