Due to the sheer short wavelength, the angle at which constructive interference in between waves occurs is unequal wavelengths.
Unequal wavelengths:Two conditions must be met to create a steady and clear interference pattern: both wave sources must be cohesive, meaning they must emit identical waves with a consistent phase difference. The waves should be monochromatic, meaning that they will have only one wavelength.As a result, the interference between waves would be limited by unequal wavelengths.Find out more about the Unequal wavelengths here:

If the velocity of an airplane is doubled, then its kinetic energy
will increase by a factor of
Answer:4
Explanation:
If the velocity of an airplane is doubled, then its kinetic energy will increase by a factor of four.
What is kinetic energy?The ability of an object to do work by virtue of its motion.
The kinetic energy is represented mathematically as
K.E = 1/2 mv²
where v is the velocity with which the object is moving and m is its mass.
When the velocity is doubled, kinetic energy is
K.E' = 1/2 m(2v)²
K.E' =4 x ( 1/2 mv²)
Thus, airplane's kinetic energy will increase by a factor of four.

Which best illustrates projectile motion
A pictorial diagram of a person hopping sideways at 5 different positions. The start and end positions are on the ground. The correct option is D.
What is projectile motion?Projectile motion is the motion of an artifact thrown or projected into the air that is only affected by gravity's acceleration. The object is known as a projectile, and its path is known as its trajectory.
Any object that is cast, fired, flung, heaved, hurled, pitched, tossed, or thrown is considered a projectile.
Throwing a ball straight up, kicking a ball at an angle to the horizontal, or simply dropping things and letting them fall are all examples of projectile motion.
The pictorial diagram of a person hopping sideways in five different positions best illustrates projectile motion. The starting and ending points are on the ground.
Thus, the correct option is D.

E20 GOT A HUNDRED PERCENTA bicyclist with a mass of 50 kg is traveling at a rate of 30 m/s. It accelerates to a rate of 50 m/s in 5 seconds. What is the net force acting on the bicycle?
Answer:
200 N
Explanation:
There is only two needed factors in play here; the mass and acceleration
According to Newton's 2nd Law: F = m*a
Now Acceleration is Velocity over Time, so we have another factor in play: Acceleration = 50-30/5 = 20/5 = 4m/s^2
Net force = (50 kg)(4 m/s^2) = 50*4 = 200 Newtons
The force that acts on an object lying on a surface, acting in a direction perpendicular to the surface is called ____________

What makes the eardrum vibrate?
Answer:
The sound waves are gathered by the outer ear and sent down the ear canal to the eardrum. The sound waves cause the eardrum to vibrate, which sets the three tiny bones in the middle ear into motion. The motion of the three bones causes the fluid in the inner ear, or cochlea, to move.
~+lil more info+~
The sound waves go through the ear canal into the middle ear, which includes the eardrum (a thin layer of tissue) and three tiny bones called ossicles. The sound causes the eardrum to vibrate. The ossicles amplify these vibrations and carry them to the inner ear.

When a 0.292 kg mass on a string is swung at 8.45 m/s, it feels a centripetal acceleration of 78.9 m/s^2. What is the radius of the swing? (Unit = m)
Answer:
0.905
Explanation:
right answer
The radius of the swing is 0.905 m
Circular motionFrom the question, we are to determine the radius of the swing
Using the centripetal acceleration formula
[tex]a_{c}= \frac{v^{2} }{r}[/tex]
Where [tex]a_{c}[/tex] is the centripetal acceleration
v is the velocity
and r is the radius
From the given information,
v = 8.45 m/s
[tex]a_{c} = 78.9 \ m/s^{2}[/tex]
Then,
[tex]78.9 = \frac{8.45^{2} }{r}[/tex]
[tex]r = \frac{8.45^{2} }{78.9}[/tex]
[tex]r = \frac{71.4025}{78.9}[/tex]
r = 0.905 m
Hence, the radius of the swing is 0.905 m

Why do temperatures differ between air, land, and water?
Answer:the ocean water isn't moving into or through the atmosphere as a result of the sun's heating of the water, convection isn't the process influencing air and water temperature difference. The heat of the ocean is being given off radiated into the air, making the air substantially warmer
Explanation:
What happens to the pressure as air rises from the ground into the atmosphere?
Does it increase or decrease?
Answer:

Which element accumulates in the environment due to the use of
fertilizers?
A. oxygen
B. hydrogen
C. nitrogen
D. carbon
To Find :
Which element accumulates in the environment due to the use of fertilizers.
Solution :
Most of the fertilizers used in daily practice are nitrogen fertilizers .
When soil became waterlogged, soil organisms take the oxygen they need from nitrates, leaving the nitrogen in a gaseous form which escapes into the air.
Also, nitrogen is very stable and did not participate in most of the reactions.
So, nitrogen is accumulates in the environment .
Therefore, option C. is correct.

What are electromagnetic waves?
Answer:
Em are waves that are created as a result of vibrations between an electric field and a magnetic field.
Explanation:
Answer:
Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.
A changing magnetic field will induce a changing electric field and vice-versa the two are linked. These changing fields form electromagnetic waves.This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
