Answer:
4.86 × 10^-7m
Explanation:
Wavelength = C/f
C (Speed) of light = 3 × 10^8
f = 6.17 × 10^14
Wavelength = (3 × 10^8)/ (6.17 × 10^14)
= 4.86 × 10^-7m
Answer:
The answer is:
Explanation:
1. The pressure of the gas increases. I think is incorrect because there is a direct proportion between number of particles and pressure, if the number of particles diminishes, then, the pressure diminishes.
2. The pressure of the gas remains the same. It's incorrect if one diminishes also the other will diminish
3. The number of collisions of gas particles decreases.
I think this is the correct one, if there are less particles, then they will interact less and the collisions will decrease.
4. The number of collisions of gas particles remains the same. It's incorrect the number of collisions could not stay the same due to the number of particles is lower.
Answer:
Base
Explanation:
Why is Alka-Seltzer a base?
Alka-Seltzer contains sodium bicarbonate and citric acid. The sodium citrate acts as an antacid. Excess sodium bicarbonate from the Alka-Seltzer acts to neutralize base.
Answer:
aluminium is more reactive than carbon. carbon is used to displace less reactive metals from their compounds. this happens since the carbon reacts with the other substance(s) in the compound, and the less reactive metal does not.
Answer:
the earth is tilted towards the sun
Explanation:
In the context, there is a sun and earth system and at a certain point when the earth is moving in its orbit around he sun, some point on the earth experiences the summers season. This is because at this point of the earths revolution, the point on the earth is facing the sun and is also tilted towards the sun. So at this point the sun rays fall directly at the surface. While the place which is tilted away from the sun, experiences winter season.
