Answer:

Waves are disturbance of the space (or of a medium) that consist of periodic oscillations that carry energy without  carrying matter.

Waves can be of two types:

- Mechanical waves: they are transmitted through the oscillations of the particles in a medium

- Electromagnetic waves: they are oscillations of the electric and magnetic fields. These are the only waves that  can travel in a vacuum

Waves consist of periodic vibrations of the particles in a medium that can oscillate in two directions:

- Back and forth along the direction of motion of the wave --> these waves are called longitudinal waves

- Up and down, so perpendicular to the direction of motion of the wave --> these waves are called transverse waves

Waves always propagate from a precise point in space, called source of the wave. So, waves are generated by this source, that somehow does work on the particles of the surrounding medium, and therefore producing the oscillation that then is transmitted through all the space around the source.

A charged particle is placed in an external magnetic field and it is moving in a circular path of radius 26m.The magnetic force
ElenaW [278]

Answer:

208 Joules

Explanation:

The radius of the circular path the charge moves, r = 26 m

The magnetic force acting on the charge particle, F = 16 N

Centripetal force, F_c = m·v²/r

Kinetic energy, K.E. = (1/2)·m·v²

Where;

m = The mass of the charged particle

v = The velocity of the charged particle

r = The radius of the path of the charged particle

Whereby the magnetic force acting on the charge particle = The centripetal force, we have;

F = F_c = m·v²/r = 16 N

(1/2) × r × F_c = (1/2) × r × m·v²/r = (1/2)·m·v² = K.E.

∴ (1/2) × r × F_c = (1/2) × 26 m × 16 N =  = (1/2)·m·v² = K.E.

∴ 208 Joules = K.E.

The kinetic energy of an particle moving in the circular path, K.E. = 208 Joules.

We can model the human back as a pivoted rod?
3241004551 [841]

Answer:

So the answer is yes, we can the back be shaped like a spinning rod

spinal column that is approximated by a long and narrow rod,

Explanation:

The bone system of the body is very well modeled in physics, the back has a spinal column that is approximated by a long and narrow rod, this rod is fixed in the lower part to the coccyx and has a weight in the upper part (head), this rod has longitudinal vertical movement and twisting movement around the lower part of the bar.

So the answer is yes, we can the back be shaped like a spinning rod
