The term 'wave' is used to refer to a disturbance that transfers energy from one place to another. Waves move energy, not matter, over distances.
The correct option is A.
In groundwater, a "wave" refers to the movement of water through porous subsurface materials, such as soil or rock. These waves can be influenced by various factors, including hydraulic gradients, geological properties, and recharge rates. Groundwater waves can propagate both vertically and horizontally, affecting the flow and distribution of groundwater in underground aquifers. Understanding these waves is crucial for managing and sustaining groundwater resources, as they impact water availability, quality, and the overall behavior of aquifer systems, influencing vital aspects of groundwater management and environmental conservation.
A disturbance that transfers energy from place to place is called a wave. Waves move energy, not matter, across distances. An easy example to visualize this concept is if you throw a pebble into a pond. The energy created by the pebble's impact causes ripples, or waves, to move out from the point of impact. In this case, the water itself doesn't travel across the pond - only the energy does. The other terms - medium, vibration, and compression, all play roles in the transmission of waves, but they are not the name for the energy transfer itself. A medium is what a wave moves through (like air or water), a vibration is a type of movement that can create waves, and a compression is a part of a certain kind of wave. However, the correct term for the energy transfer you're describing is 'wave'.
Hence The correct option is A.

Answer: Option (a) is the correct answer:
Explanation:
A wave is defined as the transfer of energy from one place to another and no exchange of matter.
Whereas medium is a substance through which wave or energy can be transported from one point to another.
On the other hand, vibration is the back and froth motion of particles of a substance or matter.
And compression means to bring the particles of a substance together by increasing the pressure.
Thus, we can conclude that a disturbance that transfers energy from place to place is called a wave.

D. 21.82
Answer: the correct options are
- were once connected
- are slowly drifting
Explanation: The continent is the main land mass of the earth which includes the following:
- Asia, Africa, Europe, Australia, North America, South America, and Antarctica.
These continents were once connected forming a supercontinent called PANGAEA
during the late palaeozoic and early mesozoic eras, millions of years ago.
Alfred Wegener, who is a German meteorologist, in 1912 came up with a hypothesis that the continents are slowly drifting the earth. He called the movement continental drift.
The continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics. In recent studies, through the science of plate tectonics, we where able to understand the mechanism through which continental drift occurs. The mechanism includes:
- processes of seafloor spreading,
- rift valley formation, and
- subduction (where heavier tectonic plates sink beneath lighter ones).
Answer:
Were once connected, and Are slowly drifting
Explanation:
It's called the continental drift, At first, Wegener's theory was dismissed. No one believed that the continents moved. During the 1920s, another scientist named Arthur Holmes suggested that the magma in the earth's mantle moved through convection currents. As hot magma rose toward the crust, it cooled and then sank back down. The cycle continued over and over, causing motion that was powerful enough to move the continents. Like Wegener's theory, Holmes' idea was not accepted by the scientific community. Forty years later, geologists compared mineral and fossil samples from Africa to those in South America. The samples matched perfectly. Today, the theory of continental drift is supported by a large amount of data and evidence. The continents as a whole was once called Pangaea.
b. magnetic fields.
c. electromagnetic waves.
d. integrated circuits.
Answer:
D. electromagnetic waves.
Explanation:
on my its D but yours may be C
Answer:
349 m
Explanation:
Parameters given:
Mass of climber, m = 92.6 kg
Amount of food calories = 735
1 food calorie = 103 calories
735 food calories = 75705 calories
1 joule is equal to 0.239 calories. Therefore, 75705 calories will be 316749.72 joules.
Hence, this is the amount of work the climber must do work off the food he ate.
Work done is given as:
W = Force * distance
W = m * g * h
h = W/(m * g)
h = 316749.72/(92.6 * 9.8)
h = 349 m
