How does inertia relate to coin dropping????

Physics
1 answer:
vekshin13 years ago
3 0

Well Inertia means something wants to stay in place, and in reality that coin wants to stay in one place, If you placed it on an index card on a cup, and SLOWLY pulled it, it wouldn't be fast enough to overcome that force, if you pulled it quickly that coin would stay in place and drop into the cup.

A 1.83 kg1.83 kg book is placed on a flat desk. Suppose the coefficient of static friction between the book and the desk is 0.52
almond37 [142]

Answer:

9.4 N

Explanation:

m = mass of the book = 1.83 kg

\mu _{s} = Coefficient of static friction = 0.522

\mu _{k} = Coefficient of kinetic friction = 0.283

f_{s} = Static frictional force

F = force needed to make the book move

force needed to make the book move is same as the magnitude of maximum static frictional force applied by the desk on the book

Static frictional force is given as

f_{s} = \mu _{s} mg

Hence, the force need to move the book is given as

F = f_{s} = \mu _{s} mg

F = \mu _{s} mg

F = (0.522) (1.83 x 9.8)

F = 9.4 N

Why is electric magnet a temporary magnet
PtichkaEL [24]
The electric magnet (Electromagnetic) is temporary because you can turn it on and off.  When it's power source is gone, the magnet becomes useless.  Usually it's power source is a battery, but it could be solar with a switch.  Hope this helps.  Please give me brainliest is this helps you.
