Because the sun is not hitting the light on them and there not as bright like when we see them when it's dark.
Answer:

Explanation:
As we know that average power is the ratio of total work done and total time interval
so we will have

now we know that


so we will have


now power is given as


Firstly models are just predictors, they are not exact models. Exponential growth <span>models are good when populations are small relative to the amount of resources available. ... This is where the </span>exponential<span> model breaks down. The </span>logistic<span> function tries to compensate for this with the carrying capacity.</span>
A pressure system is a relative peak or lull in the sea level pressure distribution. The surface pressure at sea level varies minimally, with the lowest value measured 87 kilopascals (26 inHg) and the highest recorded 108.57 kilopascals (32.06 inHg). High- and low-pressure systems evolve due to interactions of temperature differentials in the atmosphere, temperature differences between the atmosphere and water within oceans and lakes, the influence of upper-level disturbances jargon as well as the amount of solar heating or radiational cooling an area receives. Pressure systems cause weather experienced locally. Low-pressure systems are associated with clouds and precipitation that minimize temperature changes through the day, whereas high-pressure systems normally associated with dry weather and mostly clear skies with larger diurnal temperature changes due to greater radiation at night and greater sunshine during the day. Pressure systems are analyzed by those in the field of meteorology within surface weather maps.
