I WILL GIVE BRAINLIEST Which of the following statements is true with regard to transverse and longitudinal waves?

1 answer:

8 0

Answer: Transverse waves have motion perpendicular to velocity, while longitudinal waves have motion parallel to velocity.

Explanation:

Transverse waves are characterized by the fact that the particles of the medium in which they propagate move transversely to the direction of propagation of the wave.

In other words, its displacement is perpendicular to the direction of propagation of the wave, being a good example the circular waves in the water.

On the other hand, Longitudinal waves are characterized by the fact that the oscillation of the particles in the medium is parallel to the direction of propagation of the wave. A good example of this is the sound wave.

MAVERICK [17]

Heya!!

For calculate frequency, lets applicate formula:

$\boxed{f=v/\lambda}$

Δ Being Δ

f = Frequency = ?

v = Velocity = 144 m/s

$\lambda$ = Wavelenght = 0,5 m

⇒ Let's replace according the formula:

$\boxed{f = 144\ m/s / 0,5\ m }$

⇒ Resolving

$\boxed{f = 288\ Hz}$

Result:

The frequency of that wave is 288 Hertz

Good Luck!!

A crane at a construction site lifts a concrete block with a mass of m = 344 kg from the ground to the top of a building with a

Rama09 [41]

Answer: Work that the motor of the crane do is 61122 joules.

Explanation:

Work is defined as the force resulting into displacement of an object.

$w=m\times g\times h$

w = work done

m= mass of object = 334 kg

g = acceleration due to gravity = $10ms^{-2}$

h = height of an object = 18.3 m

Putting in the values:

$w=334\times 10ms^{-2}\times 18.3m=61122Joules$

Thus work that the motor of the crane do is 61122 joules

Answer:

The magnetic field strength required to hold anti-protons, moving at 5.70 ✕ 10⁷ m/s in a circular path of 3.20 m in radius is 0.186 T.

Explanation:

To solve the question we note that the magnetic force on a moving charge is given by

F = q·v·B

Where

q = Charge

v = Velocity of the charge =5.70 ✕ 10⁷ m/s

B = Magnetic field

Based on Newton's second law,

Force = Mass, m × Acceleration, a = m × a

Where:

a = Acceleration

m = Mass of anti-proton = Mass of proton = 1.6726219 × 10⁻²⁷ kg

We note that for circular motion, acceleration a is given by

$\alpha = \frac{v^{2} }{r}$ .

Where:

r = Radius = 3.20 m

Therefore, for the circular motion, force, F = $\frac{m\cdot v^{2} }{r}$

Equating the magnetic force equation to the circular force equation, we have

$\frac{m\cdot v^{2} }{r}$ = q·v·B So that, we find B by making the subject of the formula as follows

$B= \frac{m\times v^{2} }{r\times q \times v}$ . Which gives

$B= \frac{m\times v }{r\times q} = \frac{(1.6726219 \times 10^{-27}) \times (5.7\times 10^{7}) }{(3.20)\times (1.602\times 10^{-19}) }$ = 0.186 T

The magnetic field strength is

B = 0.186 T

If two waves with EQUAL amplitudes and wavelengths travel through a medium in such a way that a particular of the medium is the

Ad libitum [116K]

If this were to happen then the particle would be at the node (the point in the middle where the lines meet). Therefore, the particle will not move up or down because you can see the waves interfere destructively so there is no movement at the node.

answer. The particle will remain stationary due to interference.
