Answer: Permanent magnets consist of multiple "ferromagnetic materials" I think that might be the answer, there weren't really any choices for me to choose from.

Answer:
it would be c, there are fewer atoms in the reactants than in the products, and the total mass is less in the reactants than in the products.
Explanation:
However here coefficient of friction is not given so unable to calculate.
You can calculate it by below formula.
The formula given by

Or

u is coefficient of friction
N is normal reaction.
Here..
box doesn't move means the force if limiting friction is greater than applied force.
600
mph
Velocity is the distance traveled in a given time, or
v
=
x
t
where
v
is velocity,
x
is distance and
t
is time.
Here,
x
=
3000
and
t
=
5.0
, so
v
=
x
t
=
3000
5
=
600
Don't forget units. Since the question's data is in miles and hours, the units will be miles per hour, or mph, so
3000
miles
5
hours
=
600
miles
hour
=
600
mph
