Answer:
Cumulus Congestus & Cumulonimbus Clouds
Answer:
Slightly above 20°c
Explanation:
The resistivity of silver is 1.59 x 10-8Ωm{ as discovered by experiment from scientist}
The resistivity of tungsten at 20°c is 5.6x10-8Ωm
We see the value is just an approximation of 4 times not exactly.
Answer:
1. Burning coal contributes to sulfur aerosols in the stratosphere; these sulfur aerosols have moderated global warming.
Explanation:
Sulfur aerosols both absorb as well as scatter solar radiation coming from the sun , thus saving the earth from getting wormed up . In this way it has moderating effect on the global warming . This is also called global dimming effect. Less of the solar radiation is able to reach earth surface due to these aerosol.
The definition of density is
Density = (mass) / (volume)
Multiply each side by 'volume' : (density) x (volume) = (mass)
Divide each side by 'density' : Volume = (mass) / (density)
The vibration is thermal energy ("heat" energy which every object possesses).
The second one is kinetic energy ("motion" energy of a massive object)
