The particle motion in surface waves is a combination of longitudinal and transverse motion.

Further Explanation:

According to the vibration of the particle, the waves are classified into two categories:

Transverse Waves

Longitudinal waves

Transverse Waves:

The transverse waves are the waves in which the motion of the wave particle is perpendicular to the direction of motion of the waves.

Example: The electromagnetic waves, vibrations produced in a guitar string etc.

Longitudinal waves:

The longitudinal waves are the waves in which the motion of the wave particle is along the direction of propagation of the wave.

Example: Sound waves, seismic waves etc.

The waves produces on the surface are considered to be the combination of the transverse as well as the longitudinal waves because during its motion on the surface, the wave particles vibrate perpendicular to the surface as well as along the direction of propagation of the wave.

Thus, the particle motion in surface waves is a combination of longitudinal and transverse motion.

<h3>Answer;</h3>

B.)neither longitudinal nor transverse

<h3>Explanation;</h3>

Longitudinal waves are waves in which the vibration of particles is parallel to the direction of the wave motion.
Transverse waves on the other hand are those waves in which the vibration of particles is perpendicular to the direction of the wave motion.
In surface waves particles in the medium of transmission move in a circular motion. Therefore, they are neither transverse waves nor longitudinal waves.

PLEASE HELP!! Newtons first law states that if an objects velocity is changing a __________ must be acting on it. Question 1 opt

Anika [276]

Newtons first law states that if an objects velocity is changing a force must be acting on it.

Explanation:

Newton's first law of motion states that:

"An object at rest (or in uniform motion) will remain at rest (or will continue moving with the same velocity) unless acted upon an unbalanced force"

We can apply this law to a daily life example:

Take a book at rest on a table: the forces acting on the book are balanced. If we do not apply any other force, we know that the book will remain at rest: this is exactly what is summarized in Newton's first law.
Take a space probe moving in the interstellar space, very far from any planet or source of gravitational force. Since there are no forces acting on the proble, the probe will continue moving at the same velocity (same speed and same direction) forever, unless stopped by a new force acting on it.

This means that in order to put an object at rest in motion, or to stop an object already in motion, or to change its velocity, an unbalanced force needs to be applied: otherwise, the object will continue having the same velocity (which can be either zero or non-zero), so it will continue having same speed and same direction.

What is the energy of a photon with a frequency of 1.7 × 1017 Hz? Planck’s constant is 6.63 × 10–34 J•s.

Karo-lina-s [1.5K]

The energy carried by a single photon is given by
$E=hf$
where h is the Planck's constant and f is the frequency of the photon.

The photon of our exercise has a frequency of $f=1.7 \cdot 10^{17} Hz$ , therefore its energy is
$E=hf=(6.63 \cdot 10^{-34}Js)(1.7 \cdot 10^{17} Hz)=1.1 \cdot 10^{-16} J$

Josh is designing a lab to separate a mixture of sulfur powder and iron filings. He looks at all the ways to separate a mixture

Stolb23 [73]

Answer:

D) magnetic attraction

Explanation:

Mixture consists of sulfur powder and iron filings . The former is non magnetic and the later is magnetic material . The best way to separate them is to use a magnet . This method is called magnetic separation method . A magnet will attract the iron filling but the sulfur will remain un-attracted . Thus, the two will get separated from each other.

A wire 40cm long and of diameter 0.60mm has a resistance of 1.5 ohm what is the resistivity of the material of which it is made

zavuch27 [327]

Answer:

The resistivity of the wire is $1.05\times 10^{-6}\ \Omega-m$

Explanation:

We have,

Length of a wire is 40 cm or 0.4 m

Diameter of a wire is 0.60 mm

Radius is 0.3 mm or 0.0003 m

Resistance of a wire is 1.5 ohm

Now we need to find the resistivity of the material of which it is made. The resistance of a wire in terms of its resistance, length and area is given by :

$R=\rho \dfrac{l}{A}$

$\rho$ = resistivity

$\rho=R \dfrac{\pi r^2}{l}\\\\\rho=1.5\times \dfrac{3.14\times (0.0003 )^2}{0.4}\\\\\rho=1.05\times 10^{-6}\ \Omega-m$

So, the resistivity of the wire is $1.05\times 10^{-6}\ \Omega-m$ .
