Thinking about Planck's law, the Red star would give off the most orange light.
According to Planck's Law, distinct atoms and molecules can emit or take in power in discrete portions simplest. The smallest amount of strength that can be emitted or absorbed inside the form of electromagnetic radiation is called quantum.
Planck's Law describes the quantity of spectral radiance at a particular wavelength radiated through a black body in equilibrium. The equation is E=hv.
The floor temperature of a celeb determines the color of mild it emits. Blue stars are warmer than yellow stars, which are hotter than red stars. The bright orange celebrity Arcturus is particularly noteworthy for its massive right motion, The color is a characteristic of their floor temperatures.

Answer:
Explanation:
We shall apply Bernoulli's formula to solve the problem . It is as follows .
P + ρ gh + 1/2 ρ v² = constant .
P₁ + ρ gh + 1/2 ρ v₁² = P₂ + ρ gh + 1/2 ρ v₂²
P₁ + 1/2 ρ v₁² = P₂ + 1/2 ρ v₂²
P₁ - P₂ = 1/2 ρ (v₂² - v₁² )
= .5 x 1,1 ( 30² - 20² )
= 275 N / m²
velocity over moon roof is high , pressure will be lower there by 275 N / m²
Given pressure difference already existing = 90500 - 90000 = 500 N / m²
Additional pressure difference due to velocity difference = 275 N / m²
Total pressure difference = 275 + 500 = 775 N / m²
Area of roof = .5 m²
Total force acting upwards on the roof
= .5 x 775 N
= 387.5 N .
<u>Answer</u>:
<em>Dog drinking water after it feels thirsty is an example of an organism responding to its internal environment to maintain homeostasis.
</em>
<u>Explanation</u>:
The regulation of temperature of the body of an organism is called homeostasis. <em>Warm blooded organisms depend on their internal environment to maintain homeostasis while cold blooded organisms</em> completely depend on their external environment to maintain homeostasis.
The <em>body temperatures of warm blooded organisms maintain its constancy despite changing temperature of the external environment</em>. But the case of cold blooded organisms is different.
Their body temperature completely depends on the external environment and thus they have<em> several behavioral and physiological adaptations to maintain their body temperatures </em>at the comfortable level.
<em>In this example dog is a warm blooded animal and it drinks water to maintain homeostasis since water helps in thermal regulation of its body.
