Because of the greenhouse gases inside the greenhouse, and the gases trap the heat from the sun so the plant don't freeze, hope this helps
        
             
        
        
        
The period of the oscillations.T = 1.2042s
Opposition is the process of any quantity or measure fluctuating repeatedly about its equilibrium value throughout time. This process is referred to as oscillation. Oscillation, a periodic fluctuation of a substance, can also be described as alternating between two values or rotating around a central value.
Typically, the mathematical formula for the moment of inertia is
T = 2 π √(I / mgd)
Therefore, a moment of inertia
I = 9.00×10-3 + md^2 ;
I=9.00*10^{-3}+ 0.5 * 0.3^2
I=0.054
T=2
T=1.2042s

Answer:
   = +3,394 103 m / s
 = +3,394 103 m / s
Explanation:
We will solve this problem with the concept of the moment. Let's start by defining the system that is formed by the complete rocket before and after the explosions, bone with the two stages, for this system the moment is conserved.
The data they give is the mass of the first stage m1 = 2100 kg, the mass of the second stage m2 = 1160 kg and its final velocity v2f = +5940 m / s and the speed of the rocket before the explosion vo = +4300 m / s
The moment before the explosion
       p₀ = (m₁ + m₂) v₀
After the explosion
       pf = m₁  + m₂
 + m₂ 
      p₀ = [texpv_{f}[/tex]
      (m₁ + m₂) v₀ = m₁  + m₂
 + m₂  
Let's calculate the final speed (v1f) of the first stage
       = ((m₁ + m₂) v₀ - m₂
 = ((m₁ + m₂) v₀ - m₂  ) / m₁
) / m₁
      
       = ((2100 +1160) 4300 - 1160 5940) / 2100
 = ((2100 +1160) 4300 - 1160 5940) / 2100
       = (14,018 10 6 - 6,890 106) / 2100
 = (14,018 10 6 - 6,890 106) / 2100
       = 7,128 106/2100
 = 7,128 106/2100
       = +3,394 103 m / s
 = +3,394 103 m / s
come the same direction of the final stage, but more slowly
