    Answer: the waves probably hits an open cavity

    Explanation:

    Sound waves transfers energy in form of vibration through water,the speed of sound is greatest in solids followed by liquids and gases,for we to observe such a reduction from 4000m/s to 1500m/s that means it sound had been transmitted through air like open cavity seen in intrusive rock beneath the earth.

    Options:

    a) A different kind of rock

    b) An underground lake

    c) An open cavity

    d) A pile of dinosaur bones

    Answer:

    Option B. An underground lake

    Explanation:

    The speed of sound in water ranges from 1450 m/s to 1500 m/s. The speed of the sound wave changes because it has crosses two media of different densities. This wave is bound to have a change in direction because of change in the density and speed of the media it passes.

    The 1500 m/s speed in the second medium shows that the medium is a pool of water. The only option that applies is an underground lake

    Answer: an underground lake

    Explanation:In general, sound (mechanical waves) travels faster in solids than in liquids, and faster in liquids than in gases. This is because the speed of the mechanical waves is determined by a relationship between the elastic properties of the medium in which they are propagated and the mass per unit volume of the medium (that is:density).

    In other words: The speed of sound varies depending on the medium through which the sound waves travel.

    So, if we are told the sound wave initially had a speed of 4,000 m/s and it suddenly decreases to 1,500 m/s, this means the sound waves passed from a solid medium to a liquid medium.

    Hence, the correct option is: an underground lake.

    OverLord2011 [107]

    Answer:

    y_lower = 0.915 m,   y_superior = 1,905 m

    Explanation:

    In this exercise we use the law of reflection for a flat mirror.

    θ’= θ

    To see the feet of the person a ray of light that part of them must reach the bottom of the mirror and its reflection has to reach the eyes.

    As the law of reflection the incident and reflected angles are equal, the distance from the floor to the point where the two rays (incident and reflected) touch the mirror must be symmetrical, oses from the floor

    y = 1.83 / 2 y = 0.915 m

    To see the head, a ray of light that comes from the tip of the head and is reflected in the mirror must reach the eyes. As the head is 0.15 m above the eyes and the incident and reflected rays have the same angle, the mirror must be at half the height, that is, the mirror is 0.075 m below the tip of the head.

    In summary

    * the bottom of the mirror is 0.915 m from the ground

    * the top of the mirror is at 1.83 + 0.075

    y_superior = 1,905 m

    What is mass and the temperature ?​

    german

    Answer:

    Mass is a measure of the amount of matter in an object.

    A measure of the warmth or coldness of an object or substance with reference to some standard value.

    Explanation:

    If two objects have the same mass, the object with the higher temperature has greater thermal energy. Temperature affects thermal energy, but temperature isn't the same thing as thermal energy. That's because an object's mass also affects its thermal energy.

    Answer:

    From  the given information we can infer that the field is not conservative.

    Explanation:

    For a conservative field the work done on an object in moving it from a position given by co-ordinates to another position with co-ordinates  shall be independent of the path we take in between to reach our final position (by definition of a conservative field). But in the given case since the initial and the final position of both the curves coincide but the work done along both the paths is different thus we conclude that the field is not conservative.
