Answer:
non metals and non metals=covalent bond
metals and non metals =ionic bond
transfer all the valence electron to form ionic bond
share valence electron to form covalent bond
Answer:
<h2><u>✍</u><u> </u><u>What is quantum physics?</u></h2>
- ➳ It's the physics that explains how everything works; the best description we have of the nature of the particles that make up matter and the forces with which they interact.
- Quantum physics underlies how atoms work, and so why chemistry and biology work as they do.
Answer:
or 0.32 μm.
Explanation:
Given:
The radiations are UV radiation.
The frequency of the radiations absorbed (f) =
The wavelength of the radiations absorbed (λ) = ?
We know that, the speed of ultraviolet radiations is same as speed of light.
So, speed of UV radiation (v) =
Now, we also know that, the speed of the electromagnetic radiation is related to its frequency and wavelength and is given as:
Now, expressing the above equation in terms of wavelength 'λ', we have:
Now, plug in the given values and solve for 'λ'. This gives,
Therefore, the wavelength of the radiations absorbed by the ozone is nearly or 0.32 μm.
Momentum = mass * velocity
= 1400 * 10
= 14000 kg m per sec
