Answer:
Percolation of water through the soil.
Explanation:
When a tray containing a mixture of dough and sand is propped on one end of the tray with bricks then there is a slope from one end of the tray to the other end of the tray.
When water is poured on the higher end of the tray then the it tries to flow from the higher altitude to the lower altitude of the tray by the process of percolation through the granular spaces created due to the mixing of sand in the dough. Sand being granular in structure is easily permeable to water and passes water easily through its tiny pores.
Similar is the process of percolation of water through the layers of soil on the earth which also contains granular particles in them.
<span>the formula q = 375 g * 25 C * 4.186 J / (g*C) = 39,243.75 J q represents the heat in Joules , m the mass in grams, difference of temperature in Celsius degree, and 4.186 J/(g*C) is the specific heat of water( I assume the water is in liquid from and will remain liquid). Approximately 39.24 kJ once you round and transform to kJ..1 kJ=1000J</span>

Answer: D
Explanation: Look at the figure, we can conclude that the correct answer is
X: Low potential energy
Y: High potential energy
Z: Flow of electrons
Because electrons flow where there is difference in potential energy. And electrons move from a region of high potential energy to a region of low potential energy.
Since the arrow is pointing to X, that means
Z is the flow of electrons, X is of low potential energy and Y is of high potential energy.
Answer:
Can behave both as a particle and wave
Explanation:
Electromagnetic wave has the electric and magnetic wave propagating/oscillating together. Electromagnetic waves such as x Ray, gamma ray, radio waves are important in health care and modern information technology .
Electromagnetic waves have particles such as the electrons and protons. They are responsible for the existence of electromagnetic waves by the charged particles vibrating. Electromagnetic waves behave as waves majority of the time. Electromagnetic energy is released in distinct packs of energy called photons which are particles but acts like waves.
