Given :
Mass of brick, m = 2 kg.
Speed of block, v = 12 m/s .
To Find :
The momentum of the brick.
Solution :
We know, momentum of any object is given by :
Momentum = Mass × Speed
Momentum = m × v
Momentum = 2 kg × 12 m/s
Momentum = 24 kg m/s
Therefore, the momentum of the brick is 24 kg m/s .
D. argon (Ar), a noble gas
Explanation:
- Argon is the element on the third period with the highest first ionization energy.
- Ionization energy is a measure of the readiness of an atom to lose an electron.
- Weakly held electrons in the valence shell are easier to lose compared to the inner shell electrons.
- Across a period, ionization energy increases and since Argon is a noble gas on the periodic table, it has the highest first ionization energy.
- The energy required to remove electron from a filled orbital or inert-gas configuration is very great.

Answer:
When the acceleration of the elevator is going upward, the rider experiences a sensation of being heavier than his normal weight due to the upward normal force being more than the rider's weight.
True
Explanation:
Human impact on the ecosystem would most likely lead to secondary succession over primary succession is very correct.
Most human activities does lead to destruction of soil.
- The bulk of human activities destroys the habitats in an ecosystem.
- Farming, mining, deforestation, construction etc only results in habitat loss.
- The top cover layer of the earth is still preserved which is the soil.
- Even when removed, they are taken to another place.
- Primary succession takes place in an area where there is no soil initially.
- Human activities does not really remove the soil on earth.
