It hasn't moved from its original spot so displacement is 0
Chemosynthetic bacteria or chemoautotropic bacteria is the new bacteria that was found by scientists in a hot water sulfur spring that uses sulfur as a source of energy instead of sunlight. This kind of bacteria can survive at a higher temperature than most organisms can.The bacteria uses the toxic hydrogen sulfide to produce organic materials by the process of chemosynthesis. These bacteria are a source of life for several other organisms that flourish in such conditions. The bacteria grows and forms a thick mat and this attracts several other organisms as the bacteria becomes a source of food.
metals are conductors, meaning that heat travels through it better than insulators such as plastic (commonly used for pan handles)
Therefore, to avoid the heat burning hands, most pans don't have metal handles.
The sentence can be completed as follows:
"<span>A major difference between radio waves, visible light, and gamma rays is the
energy of the photons, which results in the different photon frequencies and wavelengths."
In fact, gamma rays have greater energy than visible light and visible light has greater energy than radio waves. The energy E of a photon is related to its frequency, f, by
</span>

<span>where h is the Planck constant. We see from this formula that the higher the frequency, the greater the energy. Instead, the wavelength is inversely proportional to the frequency:
</span>

<span>where c is the speed of light. Since the frequency is directly proportional to the energy, this means that the wavelength is inversely proportional to the energy.</span>
Answer:
1.97 * 10^8 m/s
Explanation:
Given that:
n = 1.52
Recall : speed of light (c) = 3 * 10^8 m/s
Speed (v) of light in glass:
v = speed of light / n
v = (3 * 10^8) / 1.52
v = 1.9736 * 10^8
Hence, speed of light in glass :
v = 1.97 * 10^8 m/s
