<h3><u>Answer;</u></h3>

Magnetic field

<h3><u>Explanation;</u></h3>

Magnetic field is the area around a magnet in which magnetic force is felt. It describes the influence of magnets and electrical currents.
Magnetic fields are shown by continuous lines of force which emerge from north-seeking magnetic poles and enter to the south poles. Density of the lines indicates the strength of magnetic field.

Suppose the coefficient of static friction between a quarter and the back wall of a rocket car is 0.383. At what minimum rate wo

djverab [1.8K]

Answer:

25.59 m/s²

Explanation:

Using the formula for the force of static friction:

$f_s = \mu_s N$ --- (1)

where;

$f_s =$ static friction force

$\mu_s =$ coefficient of static friction

N = normal force

Also, recall that:

F = mass × acceleration

Similarly, N = mg

here, due to min. acceleration of the car;

$N = ma_{min}$

From equation (1)

$f_s = \mu_s ma_{min}$

However, there is a need to balance the frictional force by using the force due to the car's acceleration between the quarter and the wall of the rocket.

Thus,

$F = f_s$
