Longitudinal waves are mechanical waves because they require material medium for their propagation.
Mechanical wave is a type of wave that requires material medium for their propagation.
- Sound wave is an example of mechanical wave because it requires material medium for its propagation.
- Sound waves are longitudinal waves because they travel parallel to the mode of their vibrations.
Thus, we can conclude that longitudinal waves are mechanical waves because they require material medium for their propagation.

I’m pretty sure it’s circuit three.
The final common speed of the two carts will be 69.3 m/sec.The momentum conservation principle is applied.
<h3>What is the law of conservation of momentum?</h3>
According to the law of conservation of momentum, the momentum of the body before the collision is always equal to the momentum of the body after the collision.
Unit conversion:
1 metric tons = 1000 kg
Given data;
m₁= 11.6 metric ton =11600 kg
m₂ = 23.2 metric ton = 23200 kg
Let v represent the combined velocity of the two carts once they are connected, and let u represent the starting velocity of cart 1 when it reaches the bottom.
Considering energy conservation;
From the conservation of momentum principle;
Hence, the final common speed of the two carts will be 69.3 m/sec.

Answer:
x_total = 3.07 m
Explanation:
Let's analyze the situation presented, in this case we have the data to find the angle of incidence and with the law of refraction we can find the angle of refraction.
Let's start looking for the angle with which the laser pointer reaches the water, let's use trigonometry
tan θ₁ = 1.0 /2.0
θ₁ = tan⁻¹ 0.50
θ₁ = 26.57º
now let's use the law of refraction to find the angle of refraction (in water)
n₁ sin θ₁ = n₂ sin θ₂
the refractive index of air is n₁ = 1 and that of water n₂ = 1.33
sin θ₂ =
sin θ₂ =
θ₂ = sin⁻¹ 0.3363
θ₂ = 19.65º
now we can find the distance from the entry point to the water to the lenses
tan θ₂ = x₂ / 3
x₂ = 3 tan θ₂
x₂ = 3 tan 19.65
x₂ = 1.07 m
the total distance from the edge of the pool is
x_total = 2 + x₂
x_total = 2 + 1.07
x_total = 3.07 m
Answer: Calculate the work input in a pulley by using the previous readings in the correct mathematical equation. : Work (W) equals force (f) multiplied by distance (d), or W=fd. The work done by the pulley is the equation of weight (w) multiplied by height traveled (h).
