Answer:
The centripetal force is 663.95 N.
Explanation:
Given that,
Mass of the child, m = 19 kg
Angular velocity of the merry-go-round,
Distance from the center, r = 2 m
We need to find the centripetal force acting on the child. The centripetal force is given by the formula as :
F = 663.95 N
So, the centripetal force is 663.95 N. Hence, this is the required solution.
Answer:
See, the string is made of nickel and steel (iron+carbon), materials that are ferromagnetic. That is, a magnet attracts guitar strings. When this ferromagnetic metal vibrates in the magnetic field of the pickup, that disturbs the red field lines which also cross through the coil (not shown).

Answer:
1,580,088,782,700
Explanation:
There are 90,021 drops of water in one gallon, so multiplying all together. Roughly 1,580,088,782,700 drops of water will fall. Or about 1 1/2 trillion drops.
