Answer: Radiation
Explanation:
There are three ways in which the thermal transfer occurs: 
    1. By Conduction, when the transmission is by the <u>direct contact</u>.
    2. By Convection, heat transfer <u>in fluids </u>(like water or the air, for example).  
    3. By Radiation, by the <u>electromagnetic waves</u> (they can travel through any medium and in <u>vacumm</u>)
So, in the outter space is vacuum, this means the energy cannot be transmitted by convection, nor conduction. It must be transmitted by electromagnetic waves that are able to travel with or without a medium, and this is called radiation.
 
        
                    
             
        
        
        
Answer:
A chair at rest on the floor has two forces acting on it its own weight that pulls it downward and the floor pushing upward on the chair, both of these forces are acting on it but the net force is 0, so the chair remains at rest and its velocity stays at 0.

The satellite executes a rotation motion around the earth, because Earth's force of attraction plays the role of centripetal force:
Fa=Fcp=>k*Mp*m/(Rp+r)²=mv²/(Rp+r)=>v=√(k*Mp/(Rp+r))=√(6.67*10⁻¹¹*5.98*10²⁴/(6371*10³+1000*10³))=√(39.88*10¹³/(7371*10³))=√(5.41*10⁷)=7355.53 m/s
Check the calculations again

Wee can use here kinematics
as we know that

for shorter tree we know that


now since we know that other tree is twice high 
So height of other tree is y = 39.2 m
now again by above equation



so the time taken is 2.83 s
