How are longitudinal and transverse waves alike? How are they different?
Answer:
Longitudinal and transverse waves have many similarities and differences.
Explanation:
Similarities:
Mechanical waves can be transverse and longitudinal waves.
Transverse and longitudinal waves both have wavelengths and frequencies.
They both have amplitudes
Both waves can travel through a medium or not, but it depends on whether is an electromagnetic or a mechanical wave.
Differences:
Electromagnetic waves can only be transverse.
The particles of the medium in a longitudinal wave move parallel to the direction (motion) of a wave. It is in this back and forth motion.
The particles of the medium in a transverse wave move perpendicular to the direction (motion) of a wave. This means that there would be right angles showing that they are perpendicular.
Longitudinal waves have rarefactions and compressions.
These rarefactions and compressions are used to measure the wavelength of a wave. For instance, a wavelength in a longitudinal wave is measured from rarefaction to rarefaction
Transverse waves have troughs and crests.
Amplitude in a transverse wave is measured from the midline to the crest of trough.
Amplitude in a longitudinal wave is measured based on how closely packed the particles of the medium are
I hope this helps
Answer:
Longitudinal and transverse waves are mechanical waves, so both carry energy through particles of matter. Longitudinal waves transfer energy parallel to the direction of wave motion, and transverse waves transfer energy perpendicular to the direction of wave motion.

g Two identical toy cars are held at rest on top of identical ramps. Car A rolls down the ramp, through a loop and then moves along a horizontal surface. Car B starts from rest at the same height, but it does NOT complete the loop. It is found that Car B has a faster speed at the finish line than Car A. What is the BEST explanation for why
Answer:
The kinetic energy of Car B is greater than the kinetic energy of Car A at the finish line.
Explanation:
Both objects have the same kinetic energy at the bottom of the ramp since the ramps are identical. Since Car A passes through the loop, it losses kinetic energy before it gets to the horizontal road and thus decreasing its speed. Car B does not go through the loop so its speed as it gets to the horizontal surface is its speed at the bottom of the ramp.
As both cars move on the horizontal surface, their speed decrease further but since Car B starts with a greater speed than Car A on the horizontal surface, it will end with a greater speed than Car A at the finish line.
This is because, the kinetic energy of Car B is greater than the kinetic energy of Car A at the finish line.
Consult Interactive Solution 16.15 in order to review a model for solving this problem. To measure the acceleration due to gravity on a distant planet, an astronaut hangs a 0.123-kg ball from the end of a wire. The wire has a length of 1.52 m and a linear density of 4.41 × 10-4 kg/m. Using electronic equipment, the astronaut measures the time for a transverse pulse to travel the length of the wire and obtains a value of 0.0833 s. The mass of the wire is negligible compared to the mass of the ball. Determine the acceleration due to gravity.
Answer:
g = 1.19 m / s²
Explanation:
Let's solve this problem in parts.
Let's start by looking for the speed of the pulse in the wire, the wave speed is constant
v = l / t
let's calculate
v = 1.52 / 0.0833
v = 18.25 m / s
now we can use the relationship between velocity and material properties
v = [tex]\sqrt{\frac{T}{\mu } }[/tex]
T = v² μ
let's calculate
T = 18.25² 4.41 10-4
T = 1.4688 10-1 N
finally let's use the equilibrium condition
T - W = 0
W = T
m g = T
g = T / m
we calculate
g = 1.4688 10⁻¹ / 0.123
g = 1.19 m / s²
PLEASE ILL GIVE BRAINLIST Which term describes the high point of a transverse wave?
O A. Crest
O B. Compression
O C. Rarefaction
O D. Trough
Answer:
I belive that the answer is the A
Crest describes the high point of a transverse wave. Therefore, the correct option is option A.
Transverse waves are those which oscillate in directions that are opposite to the wave's forward motion. Electromagnetic radiation, seismic waves, or water surface ripples are all examples of transverse waves.
A simple transverse wave can be represented by a sine or cosine curve because any point's amplitude—that are, its distance from the axis—is proportional to the sine (or cosine) associated with that angle. Crest describes the high point of a transverse wave.
Therefore, the correct option is option A.

Answer:
3.3*10^-28j
Explanation:
A P E X
The energy of an electromagnetic wave that has a frequency of 5.0 * 10^5 Hz is 3.3 * 10 ^ -28 J
What is Electromagnetic waves ?Electromagnetic waves are the waves that are created as a result of vibration between an electric field and a magnetic field . They are composed of oscillating magnetic and electric field
Energy of Electromagnetic waves can be calculated by
Energy = h * f where h = plank's constant = 6.626 * 10^-34 J s.
f = frequency of electromagnetic waves
given : h = 6.626 * 10^-34 J s.
frequency = 5.0 * 10^5 Hz
Energy of electromagnetic waves = (6.626 * 10^-34 J s) *( 5.0 * 10^5 Hz)
= 33.13 * 10 ^ -29 J
= 3.3 * 10 ^ -28 J

a piece of clay with mass m is traveling with an unknown velocity in the positive x-direction, when it collides and sticks to a block of mass 3m, moving with velocity v=-3m/s. after the collision, the block and clay are stuck together and traveling with a velocity of 1 m/s in the negative x-direction. what was the original velocity of the clay mass?
Answer:
13 m in the + x direction.
Explanation:
Givens
m1 = m
m2 = 3m
v1= ? = x
v2 = - 3 m/s
v3 = v4 = - 1 m/s
Equation
Let x be the speed of the lighter object before collision.
Momentum before collision = momentum after collision
Solution
mx - 3m * 3m/s = (m1 + m2)*(-1)
m(x - 3*3m/s) = (m + 3m)(-1)
m(x - 9) = - 4m Cancel the ms
x - 9 = 4 Add 9 to both sides
x = 9 + 4
x = 13 m/s

1 gram of radium is reduced by 3.1 mg in 5 years by alpha decay.
Calculate the half-life of radium.
Answer:
1 gm = 1000 mg
N = No e^-y t where y = lambda the decay constant
N / N0 = .9969
ln .9969 = - y t
-.00310 = - 5 y
y = .00310 / 5 = .000621
So the half-life = .693 / y
T^1/2 = .693 / .000621 = 1116 or about 1120 yrs
