The region labelled with X represents the B) magnetic field

Explanation:

Magnetic fields are regions of space produced by charge in motion (e.g. a current) or by magnets, in which charged particles in motion experience a force perpendicular to their motion.

As we said, magnetic fields can be produced in two ways:

- By charged particles in motion, such as an electric current

- By a magnet

Magnets consist of two "poles", called "north pole" and "south pole" by convention, and the direction of the magnetic field is always from the North pole to the South pole. Similarly to what happens to electric charge, like poles repel each other (north-north or south-south) while opposite poles attract each other (north-south).

In this problem, we want to know what are the red arrows in the figure. We notice that the lines go from a block labelled with to a block labelled with S. These two blocks represent the poles of a magnet, with N being its North Pole and S being the South pole: therefore, the region marked with X represents the magnetic field of the magnet.

A 33.0-kg child starting from rest slides down a water slide with a vertical height of 15.0 m. (Neglect friction.)

Temka [501]

This question involves the concept of the conservation of energy.

(a) The child's speed halfway will be "12.13 m/s".

(b) The child's speed three-fourth way will be "14.86 m/s".

(a)

Using the <em>law of conservation of energy</em>:

Potential Energy Lost = Kinetic Energy Gained

$mgh = \frac{1}{2}mv^2\\\\2gh = v^2\\\\v = \sqrt{2gh}$

where,

v = speed = ?

g = acceleration due to gravity = 9.81 m/s²

h = height lost = halfway = height/2 = 15 m/2 = 7.5 m

Therefore,

$v = \sqrt{(2)(9.81\ m/s^2)(7.5\ m)}$

<u>v = 12.13 m/s</u>

<u />

(b)

Using the <em>law of conservation of energy</em>:

Potential Energy Lost = Kinetic Energy Gained

$mgh = \frac{1}{2}mv^2\\\\2gh = v^2\\\\v = \sqrt{2gh}$

where,

v = speed = ?

g = acceleration due to gravity = 9.81 m/s²

h = height lost = three-fourth way down = $\frac{3}{4}height = \frac{3}{4}(15\ m) = 11.25\ m$

Therefore,

$v = \sqrt{(2)(9.81\ m/s^2)(11.25\ m)}$

<u>v = 14.86 m/s</u>

<u />
