High-pressure systems<span> are frequently associated with light winds at the surface and subsidence through the lower portion of the troposphere. In general, subsidence will dry out an air mass by adiabatic or compressional heating. Thus, </span>high pressure<span> typically brings clear skies.</span>

Answer:
a

c
Explanation:
From the question we are told that
The mass of the stone is
The height above the top of the water is
The depth of the well is
The gravitational potential of the stone before it was released is
substituting values
The gravitation potential of the stone when it reaches the bottom of the well is
The negative shows that the potential energy of the stone as compared to the earth is reducing
substituting values
The change in the systems gravitational potential is
substituting values
Answer:
One way to test the hypothesis is to create two waves, one in the air and one on the ground at the same time. One of them for the elephant to get closer and another for the elephants to move away. Observe the reaction of the animal and with this we know which sound came first.
Explanation:
This hypothesis is based on the fact that the speed of sound in air is v = 343 m / s with a small variation with temperature.
The speed of sound in solid soil is an average of the speed of its constituent media, giving values between
wood 3900 m / s
concrete 4000 m / s
fabrics 1540 m / s
earth 5000 m / s wave S
ground 7000 m / s P wave
we can see that the speed on solid earth is an order of magnitude greater than in air.
One way to test the hypothesis is to create two waves, one in the air and one on the ground at the same time. One of them for the elephant to get closer and another for the elephants to move away. Observe the reaction of the animal and with this we know which sound came first.
From the initial information, the wave going through the ground should arrive first.
