red hot is hot, but other colours are even hotter. stars may be hotter than red hot.
there is also something calle the red shift.
 
        
             
        
        
        
Answer:External forces are forces caused by external agent outside of the system. Internal forces are forces exchanged by the objects in the system.
Explanation:or our purposes, we will simply say that external forces include the applied force, normal force, tension force, friction force, and air resistance force. And for our purposes, the internal forces include the gravity forces, magnetic force, electrical force, and spring force.HOPE THIS HELPS!!! ^w^
 
        
             
        
        
        
Answer:
Explanation:
The relation between activity and number of radioactive atom in the sample is as follows 
dN / dt = λ N where λ is disintegration constant and N is number of radioactive atoms 
For the beginning period 
dN₀ / dt = λ N₀
58.2 = λ N₀
similarly 
41 = λ N
dividing 
58.2 / 41 = N₀ / N 
N = N₀ x .70446
formula of radioactive decay 


- λ t = ln .70446 =   - .35 
t = .35 / λ
λ = .693 / half life 
= .693 / 5715 
= .00012126
t = .35 / .00012126
= 2886.36 
= 2900 years ( rounding it in two significant figures )
