The right answer is Electromagnetic waves can transfer energy through empty space.
Electromagnetic radiation refers to a form of linear energy transfer. Visible light is electromagnetic radiation, but is only a small slice of the broad electromagnetic spectrum. The propagation of this radiation does not need material to move.
if we take the example of solar energy, it spreads in space, the atmosphere until reaching the earth.
Once it reaches a material, it gives rise to many phenomena such as attenuation, absorption, diffraction and refraction, redshift, interferences, echoes, electromagnetic parasites and biological effects.
Answer:
In my own words, this summary equation tells me that:
When glucose reacts with oxygen, carbon (IV) oxide and water are given off and energy is produced.
Explanation:
Cellular respiration is known to be a metabolic reaction which actually occur in the cells of living organisms whereby chemical energy is converted into energy (ATP) and certain waste products, carbon (IV) oxide and water are released. We can simply put that cellular respiration is a process of converting sugars to energy. In the giving equation, we can see that glucose which is a sugar reacts with oxygen to give CO₂ and H₂O.
Answer:
25116 J
Explanation:
Q = m × c × ΔT
c = 4.186 J/g°C
M=200 g
So,
Q = 200 × 4.186 × (40-10)
=200 × 4.186 × 30
=25116 J
