The type of wave that occurs where two different mediums meet is known as a transverse wave. Hence, option A is correct.
What are waves?Wave is the regular, systematic spread of disturbances from one location to another. The ripples that travel on water's surface are the most well-known, but waves also exist in sound, sight, and the movement of subatomic particles.
The disturbance periodically oscillates with a set frequency and wavelength in the simplest waves. In contrast to electromagnetic waves, which can travel in a vacuum, mechanical waves, like sound, need a medium to move through. The characteristics of the medium affect how a wave travels across it.
A transverse wave's crest and trough are the high and low points, respectively. The shock absorbers and rarefactions of longitudinal waves are comparable to the troughs and crests of transverse waves. The wavelength is the separation between subsequent crests or troughs.

Explanation:
Explanation:
A simple machine that may be used the most often is called the wheel and axle. The wheel and axle has two basic parts: wheel and axle. They can be found everywhere. It has two circular objects which includes a larger disc and a small cylinder both joined at the center.The large disc is the wheel, and the small cylinder or rod is the axle. There may be two wheels attached to the axle.
There are two basic ways a wheel and axle can work together to help move things.
1. The Force is applied to the Wheel
For example, a screwdriver is an example of a wheel and axle. The handle is the wheel where the force is applied. It turns or spins and increases the force of the shaft or axle, which helps turn the screw.
Another example of force being applied to the wheel is when a doorknob is turned. The wheel (doorknob) is turned and the locking mechanism connected to the shaft turns and the door can then be opened.
2. The Force is applied to the Axle
A Ferris wheel is an example of force being applied to the axle. When the axle turns it results in the giant wheel turning. The wheel is much larger than the axle and covers more distance and area. A ceiling fan works the same way.

C. The weight of an object is the same on the Earth and the moon
Answer:
C
Explanation:
The weight of an object is 1/6 of the earth's weight in the moon
For example if your weight is 54 kg on earth,
Weight on moon=1/6 of 54=1/6 x 54 = 9kg
Answer:
C. The weight of an object is the same on the Earth and the moon
Explanation:
The mass of an object is ⅙ of earth's weight on moon. So, option (C) is the false statement.

Explanation:
Hi whats this plss???
Answer:
a) ball K <K₀, b) the speed of the ball after the collision, c) can K> 0
d) can moves in the same direction as the ball
Explanation:
a) the kinetic energy is given by
K = ½ M v²
in this case before the collision the kinetic energy of the ball is
K₀ = ½ M v₀²
After the collision the aluminum can has a certain speed, therefore the kinetic energy of the ball must decrease, the velocity of the ball after the collision is
v <v₀
therefore the kinetic energy is
K = ½ m v²
in consecuense
K <K₀
b) an evidence of this fact is to measure the speed of the ball before the collision and the speed of the ball after the collision,
c) In the case of the aluminum can, the initial kinetic energy is ero, because it is stopped
K₀ = 0
after the collision a part of the cal momentum of the ball is transferred to the can, therefore its velocity is different from zero
K = ½ m v_can²
K> 0
d) the clearest evidence of this fact is that the can moves in the same direction as the ball
6. Which of the following graphs correctly demonstrates the relationship between the
electromagnetic force and distance between charges?
Answer:
But where are the graphs
Coulomb's Law describes the relationship between electromagnetic force and the distance between charges.
What is the relationship between electromagnetic force and the distance between charges?The relationship between electromagnetic force and the distance between charges is described by Coulomb's Law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Mathematically, Coulomb's Law is expressed as:
F = k (q₁x q₂) / r²
where F is the electromagnetic force, q1 and q2 are the charges, r is the distance between the charges, and k is the Coulomb constant.
This means that as the distance between two charges increases, the force between them decreases, and as the distance decreases, the force increases. The relationship between force and distance is inverse square, which means that the force decreases rapidly as the distance increases.

According to the theory of plate tectonics, the lithosphere is separated into sections that are called tectonic plates. These plates move in different directions in response to the forces in Earth’s mantle beneath them. Which of the following correctly matches the plate movement with its description?
convergent boundary; plates move away from one another causing rift valleys and the formation of new crustal material
transform boundary; plates slide past one another in opposite directions causing the formation of faults and earthquakes
divergent boundary; as the plates come together gravity pushes the edge of one plate underneath the edge of a neighboring plate
subduction zone; as the plates come together increased pressure causes the plates to fault and fracture leading to the formation of mountains
Answer:
The correct answer is - transform boundary; plates slide past one another in opposite directions causing the formation of faults and earthquakes.
Explanation:
If the continental or oceanic plates slide past one another either in the same direction or in opposition direction forms the transform fault boundary. Due to this tectonic plate formation, no new crust is formed or subducted, but earthquake activities forms.
Convergent boundaries forms by pushing the edge of one plate underneath the other while coming together whereas plates move away from one another causing rift valleys called divergent boundary.
the refractive index of rock salt with respect to water is 1.17. What will be the refractive index of water with respect to rock salt
Answer:
1.17
Explanation:
Given that,
The refractive index of rock salt with respect to water is 1.17.
We need to find the refractive index of water with respect to rock salt.
We know that,
Refractive index = (speed of light in air or vaccum)/( speed of light in that medium)
Refractive index of rock salt with respect to ice = (speed of light in ice)/(speed of light in rock salt)
The speed of light in ice = c/1.31
The speed of light in rock salt = c/1.54
Required refractive index,
[tex]\mu=\dfrac{1.54}{1.31}\\\\=1.17[/tex]
So, the refractive index of water with respect to rock salt is equal to 1.17.

When a shopping cart rolls into a parked car on the street, It hits the car with a force of 220 newtons. The shopping cart experiences a force from the car that is how many newtons?
Answer:
220 N
Explanation:
When a shopping cart rolls into a parked car on the street, it hits the car with a force of 220 newtons.
We need to find the force the shopping cart experiences from the car.
We know that, Newton's third law of motion states that for every action there is an equal and opposite reaction.
Hence, the shopping cart experiences a force of 220 N from the car.
A capacitor with a capacitance of 50µf when connected to a battery of 400 V. The charge and energy stored on it is? a. 0.05 C and 5 J b. 0.05 C and 10 J c. 0.02 C and 4 J d. 0.08 C and 12 J
Answer:
c. 0.02 C and 4 J
Explanation:
Applying,
Q = CV................ Equation 1
Where Q = Charge, C = Capacitance of the capacitor, V = Voltage.
From the question,
Given: C = 50 μF = 50×10⁻⁶ F, V = 400 V
Substitute these values into equation 1
Q = (50×10⁻⁶)(400)
Q = 0.02 C.
Also Applying
E = CV²/2............. Equation 2
Where E = Energy stored.
Therefore,
E = (50×10⁻⁶ )(400²)/2
E = 4 J
Hence the right option is c. 0.02 C and 4 J

(a) 10N
Explanation:The sketch of the two cases has been attached to this response.
Case 1: The box is pushed by a horizontal force F making it to move with constant velocity.
In this case, a frictional force [tex]F_{r}[/tex] is opposing the movement of the box. As shown in the diagram, it can be deduced from Newton's law of motion that;
∑F = ma -------------------(i)
Where;
∑F = effective force acting on the object (box)
m = mass of the object
a = acceleration of the object
∑F = F - [tex]F_{r}[/tex]
m = 50kg
a = 0 [At constant velocity, acceleration is zero]
Substitute these values into equation (i) as follows;
F - [tex]F_{r}[/tex] = m x a
F - [tex]F_{r}[/tex] = 50 x 0
F - [tex]F_{r}[/tex] = 0
F = [tex]F_{r}[/tex] -------------------(ii)
Case 2: The box is pushed by a horizontal force 1.5F making it to move with a constant velocity of 0.1m/s²
In this case, the same frictional force [tex]F_{r}[/tex] is opposing the movement of the box.
∑F = 1.5F - [tex]F_{r}[/tex]
m = 50kg
a = 0.1m/s²
Substitute these values into equation (i) as follows;
1.5F - [tex]F_{r}[/tex] = m x a
1.5F - [tex]F_{r}[/tex] = 50 x 0.1
1.5F - [tex]F_{r}[/tex] = 5 ---------------------(iii)
Substitute [tex]F_{r}[/tex] = F from equation (ii) into equation (iii) as follows;
1.5F - F = 5
0.5F = 5
F = 5 / 0.5
F = 10N
Therefore, the value of F is 10N
A 8.6*10^ -6 C charge is places 1.00 m away from a 2.3 * 10 ^ - 4 * C charge. How large is the force of repulsion between the two charges?
Answer:
The force of repulsion is 17.802 N
Explanation:
Given;
magnitude of the first charge, q₁ = 8.6 x 10⁻⁶ C
magnitude of the second charge, q₂ = 2.3 x 10⁻⁴ C
distance between the two charges, r = 1 m
The force of repulsion is calculated using Coulomb's law;
[tex]F = \frac{Kq_1q_2}{r^2} \\\\F = \frac{9\times 10^9 \times 8.6\times 10^{-6} \times 2.3\times 10^{-4}}{1^2} \\\\F = 17.802 \ N[/tex]
Therefore, the force of repulsion is 17.802 N
