Mass ad velocity both are considered to be quantities which defines motion.

The combination of both is called quantity of motion. It is momentum.

P = mv

Dobereiner's tried to arrange the element with similar properties into group. He identified some groups having three elements each. So he called these groups 'triads'.

The atom with the smallest mass is the hydrogen atom; its mass is about 10^-27 kg. 

Geothermal energy is feasible in regions that:
1. Are over hot spots in the crust:
- Geothermal energy is generated by harnessing the heat from the Earth's crust, particularly in areas where there are hot spots.
- These hot spots are locations where molten magma is close to the surface, causing the surrounding rocks to heat up.
2. Have a high geothermal gradient:
- The geothermal gradient refers to the rate at which the temperature increases with depth in the Earth's crust.
- Regions with a high geothermal gradient are more suitable for geothermal energy production as they indicate a significant amount of heat available.
3. Have suitable geological conditions:
- The presence of permeable rocks or fractures in the Earth's crust is essential for the extraction of geothermal energy.
- These geological conditions allow for the circulation of water or other fluids through the hot rocks, which can be used to generate electricity or provide heating.
4. Are relatively close to the Earth's surface:
- Geothermal energy is easier to extract in regions where the hot rocks are closer to the surface.
- In such areas, drilling deep wells is not required, making the extraction process more cost-effective.
5. Have appropriate water resources:
- Geothermal power plants require a significant amount of water for the extraction and conversion of geothermal energy.
- Therefore, regions with ample water resources, such as underground reservoirs or nearby lakes and rivers, are beneficial for geothermal energy production.
6. Have supportive government policies:
- The feasibility of geothermal energy also depends on the presence of supportive government policies and regulations.
- Governments that incentivize and promote the development of geothermal energy can make it more financially viable and attractive for investors.
In conclusion, geothermal energy is feasible in regions that are over hot spots in the crust, have a high geothermal gradient, suitable geological conditions, are relatively close to the Earth's surface, have appropriate water resources, and supportive government policies.

The correct answer is 120 dB.

• The loud noises that continue for a prolonged period can cause High blood pressure, Eardrum damage, and Nervous breakdown.
• Noise is unwanted and undesirable sound or noise, an irritant, and a source of stress.
• The sound level meter is used for measuring the intensity of sound.
• The transport sector contributes the maximum noise.
• The roadway noise can be reduced by the use of noise barriers, limitation of vehicle speed, and alteration of roadway surface texture.
• Sound is measured in decibels.
• Noise pollution is considered to be caused by sounds louder than 120 decibels.
• The decibel scale is used for measuring the loudness of sound or noise.
• According to the research, noise pollution is the highest in a low-income neighbourhood.
• The level of sound during normal conversation is 60 dbA.
• The allowed noise level by World Health Organisation (WHO) in residential areas is 50 decibels.
• Noise pollution affects marine animal's behaviour.

Graphite is an interesting material, an allotrope of carbon (as is diamond). It displays properties of both metals, and nonmetals. However, like a metal, graphite is a very good conductor of electricity due to the mobility of the electrons in its outer valence shells.

The Catla fish is an economically very important South Asian freshwater fish. It is in the carp family Cyprinidae. It is known by many different names such as Katla, Katol, Indian Major carp, Chepti, Baudhekra, Bacha, Karakatla and Tambra. The fish is mainly found in the rives and lakes in northern India, Bangladesh, Nepal, Pakistan and Myanmar.

The third equation of motion is :- 
 ( v² - u² = 2as) 
Here,
u = initial velocity 
v =  final velocity 
a =  acceleration
s =  distance

On moving from left to right in a period, the chemical reactivity of elements first decreases and then increases.

On moving from left to right in a period, the number of valence electrons increases from 1 to 8.

On moving from left to right in a period, the atomic size decreases; the size of the atoms decreases.

The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. For ice, the melting point is 0°C at which ice a solid turn to water.
