Lanthanide Lanthanoid, also called Lanthanide
Answer:
b. I've seen a question like this before lol
Answer: option B. closer to oxygen in the case of CO2
Explanation:
Answer:
wave speed
Explanation:
A wave is a disturbance that transmits energy from one place to another without the actual displacement of the particles of the medium.
To find the wave speed we need to determine the product of its frequency and wavelength.
Wave speed = Frequency x wavelength
Frequency of wave is the number of wave that passes through a point at a unit time.
Wavelength is the displacement of a complete wave train.
Answer: Option (d) is the correct answer.
Explanation:
When heat is removed from water then there will be decrease in the kinetic energy of water particles. This is because on removing the heat, collisions between the particles will decrease as a result the energy will decrease. Thus, particles will stop moving randomly from one place to another.
Therefore, kinetic energy of the water particles decreases.
